@wheat ridge What you should keep in mind that this is very insecure right now

#

especially since you are using the default raspberry user

#

at some point this setup should be hardened

at least make sure pi has a password

Why do we always call linux & darwin unix when they're not?

#

I find that so weird.

warped nimbus Mar 14, 2020, 9:53 PM

#

Because they're "unix-like"

#

And that gets shortened to just "unix" though it's technically incorrect

#

But most people know what you really mean or don't care

#

Funnily enough, one does have to confirm when someone really does mean unix

fickle granite Mar 14, 2020, 11:48 PM

#

oddly enough, words mean what the people who use them think they mean, as opposed to what the elite wish they meant

#

e.g. much as I wish that "literally" meant "the opposite of 'figuratively'", it no longer does

Asking good questions will yield a much higher chance of a quick response:

• Don't ask to ask your question, just go ahead and tell us your problem.
• Don't ask if anyone is knowledgeable in some area, filtering serves no purpose.
• Try to solve the problem on your own first, we're not going to write code for you.
• Show us the code you've tried and any errors or unexpected results it's giving.
• Be patient while we're helping you.

You can find a much more detailed explanation on our website.

first, pdftotext takes must have 2 parameters, one input file, the other output file

you only provided one

and also given that every $file contained .pdf at the end, therefore the "$file.txt" would suffix .pdf with .txt on top, hence 'P79-1027.pdf.txt' in your error

i think it is because you need the password to open it

but idk how to change that

fickle granite Mar 24, 2020, 3:58 AM

#

that's not the kind of shared folder I was thinking of

#

I was thinking of something simple -- you create a file in the folder in one OS, it is immediately visible in the other

#

there's an option for that in virtualbox

cosmic topaz Mar 24, 2020, 4:33 AM

#

Confused at the purpose of a shebang line, and why it’s necessary to include them at the top of a script you want to execute.

#

Can anybody explain?

fickle granite Mar 24, 2020, 4:33 AM

#

it's to tell the operating system what interpreter to run the script with

#

if you leave it out, it just assumes it's a "shell script"

#

this is ancient crufty leftover from caveman times

main olive Mar 24, 2020, 5:27 AM

#

to expand on this, it is only required if you mark the script executable and execute it by itself

#

if you execute the script via the interpreter, the shebang is not necessary

#

python myscript.py # shebang not necessary

chmod +x myscript.py
./myscript.py # shebang necessary

#

@cosmic topaz

worn apex Mar 24, 2020, 5:33 AM

#

alternatively, you could create a shell script that runs the python module

#

[no-one ever seems to do that even though shebang lines aren't in POSIX and /usr/bin/env is a dirty non-portable hack]

main olive Mar 24, 2020, 6:00 AM

#

that's generally something I think is missing from POSIX

#

i shouldn't have to have two files to run one file

#

(or, well, three+, if you count the interpreter)

worn apex Mar 24, 2020, 6:32 AM

#

the problem is the shebang mechanism as traditionally implemented isn't good enough

#

can't handle multiple arguments, arguments with spaces, or execute the interpreter from $PATH [the env thing is a workaround for that, but introduces a dependency on env's own location]

#

it's damn lucky there aren't any common implementations that don't support any arguments at all, or the env thing would have been a non-starter

main olive Mar 24, 2020, 8:01 AM

#

other than implementation, you have no issues with the shebang design?

cosmic topaz Mar 24, 2020, 11:05 AM

#

@main olive

#

I still don’t get the point of it

cosmic topaz Mar 24, 2020, 11:20 AM

#

It just saves time pretty much?

#

Instead of typing in python3 nameofmyscript.py

#

You can just type in ./nameofmyscript.py?

fickle granite Mar 24, 2020, 2:13 PM

#

pretty much

main olive Mar 24, 2020, 3:09 PM

#

@cosmic topaz it also allows you to have scripts in your path

#

so you can just do myscript.py whereever you're located

cosmic topaz Mar 24, 2020, 3:40 PM

#

@main olive oh, makes sense now. Thanks

I use Emacs

Does it have support for macros?

yes, it has both kinds of macros

#

I wonder why my first sentence is red

I don't recommend it

warped nimbus Mar 26, 2020, 6:30 PM

#

Yes

#

IIRC hooks can be in any language

#

It respects the shebang

digital haven Mar 26, 2020, 6:31 PM

#

@warped nimbus ok cool - I'll try and dump something in there. What's best - so call a script from the hook that's stored in the repo, or to have the script within the hook. I've never really used hooks

#

I guess call the script rather than have it in the hook

warped nimbus Mar 26, 2020, 6:32 PM

#

If you want to commit the script to the repo then it's better to call it from the hook

#

Or if you just want to generally re-use the script in multiple repos

digital haven Mar 26, 2020, 6:33 PM

#

yeah, i want it to be viewable / accessible so all good, i'll try calling from the hook

#

I only see pre-commit hooks :

├── [ 478]  ./applypatch-msg.sample
├── [ 896]  ./commit-msg.sample
├── [3.0K]  ./fsmonitor-watchman.sample
├── [ 189]  ./post-update.sample
├── [ 424]  ./pre-applypatch.sample
├── [1.6K]  ./pre-commit.sample
├── [ 416]  ./pre-merge-commit.sample
├── [1.3K]  ./pre-push.sample
├── [4.8K]  ./pre-rebase.sample
├── [ 544]  ./pre-receive.sample
├── [1.5K]  ./prepare-commit-msg.sample
└── [3.5K]  ./update.sample

can i do post instead? or should one stick with the defaults

warped nimbus Mar 26, 2020, 6:39 PM

#

Yeah, you can

#

Those are just samples. They don't necessarily represent all supported hooks.

digital haven Mar 26, 2020, 6:40 PM

#

ok cool - i just wrote a pre-commit hook and that works... I'll have a look for post. It's just for syncing project data up to the database, so it's only really a single gsutil command

warped nimbus Mar 26, 2020, 6:41 PM

#

man githooks will show you all hooks

digital haven Mar 26, 2020, 6:41 PM

#

ace thanks

#

oh there's no post push hook 😦

Hey guys first time using cron

#

Does a cron job go in the same directory but different file than the script to be executed by it?

main olive Mar 28, 2020, 11:55 PM

#

wat

#

just use crontab -e to set a cron job to run the script you've got specified

fickle granite Mar 29, 2020, 12:35 AM

#

the "job" isn't a file

#

it's a single line in a file called (I think) /etc/crontab, but as xx says, you don't edit that file directly; instead you use a program to edit it for you

#

for Reasons®

#

Is there a way to install ubuntu alongside windows without a usb?

#

I don't have a usb and there's a curfew going on outside

#

I can't go and buy one

#

or is there a tutorial that you would recommend me on watching

main olive Mar 29, 2020, 8:03 AM

#

@main olive got a rooted phone?

main olive Mar 29, 2020, 8:30 AM

#

@main olive I have an iphone XI

#

is that rooted?

#

Well, what does rooted mean?

#

A windows mobile?

#

ah, no, I meant an Android phone. Rooted just means root access (if you're new to Unix, the root account is the most privileged account). With it, you could've used DriveDroid, which emulates bootable USB media

#

don't think that's possible at all with an iPhone

#

ughhh

#

@main olive maybe a VM could suffice until you can get an USB drive?

#

@main olive Can you link me to a vm installer?

#

it depends entirely on what VM software you want to use

#

I wanna try out ubuntu..?

#

virtualbox and vmware are the more popular ones

#

Yea sure

#

I'll go with virtualbox

#

just create a new VM in virtualbox and point it to the Ubuntu iso

#

performance is not as good when compared to running on real hardware, but you can still get a feel of how the system operates

#

@main olive Can you link me to vm?

#

There are plenty of them when I search

#

VM just means "virtual machine"... it's a concept, I can't exactly link to it

#

virtualbox is a software which lets you create virtual machines

#

..?

#

what are you confused about exactly..?

#

have you heard of virtual machines before?

#

Is virtual machine an installable software?

#

No

#

okay okay, leave the linux thing

#

I don't want it without a usb

#

no, virtual machine is just when you create a new "machine" that doesn't run directly on the host machine's hardware (like if you're using Windows right now), but is instead almost entirely implemented virtually. You can create virtual machines (called "guests"), which run on your host machine, and install operating systems on it, like Ubuntu or Windows

#

@main olive What ide/editor do you use?

#

vim

#

..

#

Are you on linux?

#

yes

#

I assume you are

#

aw man

#

Is vim good on windows?

#

I've never tried

#

ow

#

any other editors you use?

is this the place for a grep question?

digital haven Mar 29, 2020, 12:34 PM

#

@full oriole think it's as good as any... i've asked questions along those lines here before at least

full oriole Mar 29, 2020, 12:35 PM

#

Thanks @digital haven

#

I have a file, time.txt that has the following entries:
1:12 am 09:33 pm 23:12 14
When I use grep '$1[012]|[0-9]$:[0-5][0-9] [am|pm] time.txt nothing is returned.

digital haven Mar 29, 2020, 12:40 PM

#

is that the exact command you've used

#

also - what are you expecting to be returned @full oriole

full oriole Mar 29, 2020, 12:42 PM

#

Yeah. I would expect 1:12 am to be returned because in the first sub-expression in parentheses it would match 1 then the colon, then 1 then 2 then a space and the am.

#

sorry, that expression is missing a closing single quote '

digital haven Mar 29, 2020, 12:43 PM

#

just 1:12 am is what you're expecting to be returned?

full oriole Mar 29, 2020, 12:43 PM

#

Right.

digital haven Mar 29, 2020, 12:43 PM

#

why have [am|pm] then?

#

and not just am

#

also - egrep is useful if you're using regular expressions

#

eg

-> % egrep '9|3' time.txt
09:33 pm
23:12

full oriole Mar 29, 2020, 12:47 PM

#

I was going to extend the pattern to match the time 09:33 pm once I could get the first pattern to match correctly.

digital haven Mar 29, 2020, 12:48 PM

#

so do you in fact just want to return anything that isn't a time?

#

in which case

-> % egrep '[am|pm]' time.txt
1:12 am
09:33 pm

#

seems that it'd be enough

full oriole Mar 29, 2020, 12:49 PM

#

Ok, so when I use egrep with egrep '(1[012]|[1-9]):[0-5][0-9] [am|pm]' time.txt I get
09:33 pm 23:12 1:12 am

#

No, I'm working through the book Mastering Regular Expressions, and the section is about matching any time in the 24-hr time model.

digital haven Mar 29, 2020, 12:50 PM

#

ok well i don't really understand what the expected out put is

#

maybe someone else follows

full oriole Mar 29, 2020, 12:51 PM

#

Thanks @digital haven !

digital haven Mar 29, 2020, 12:52 PM

#

if i just wanted to match times then from that i'd do something like egrep '^[0-9]?[0-9]:[0-9][0-9]' time.txt

full oriole Mar 29, 2020, 12:54 PM

#

Right, that's actually the first attempt the book gives, but that could get non-sensical times like 99:99, so the next step is to refine the pattern to only returns real times.

digital haven Mar 29, 2020, 12:54 PM

#

the files not a great test case then

full oriole Mar 29, 2020, 12:54 PM

#

Totally :)

#

I'll add to it. Thanks

#

good call

main olive Mar 29, 2020, 1:30 PM

#

@full oriole something like this?

$ cat times
1:12 am
14:35 am
99:28 pm
21:99
21:22 am
9:1 pm
09:33 pm
23:12
4:25
04:25
24:12
14
$ grep -P '(?:(?:^0?[1-9]|^1[0-2]):[0-5][0-9] (?:am|pm)|(?:^[0-1][0-9]|^2[0-3]):[0-5][0-9])$' times
1:12 am
09:33 pm
23:12
04:25

#

matches only valid 12h times or valid 24h times

full oriole Mar 29, 2020, 1:31 PM

#

@main olive thanks! give me a minute to digest it ;)

#

Ah nice! What's -P do? I'm not seeing that as an option for grep in the man pages.

main olive Mar 29, 2020, 1:35 PM

#

you using GNU grep, right? my manpages have it

#

       -P, --perl-regexp
              Interpret PATTERNS as Perl-compatible regular expressions (PCREs).   This  option  is
              experimental  when combined with the -z (--null-data) option, and grep -P may warn of

main olive Mar 29, 2020, 1:40 PM

yes, it creates a non-capturing group

If not I don't understand the logic of matching ( zero or more times at the beginning.

Ah, got it!

main olive Mar 29, 2020, 1:43 PM

i'm sure this could be done with grep's common flavor of regex as well, but i'm personally more comfortable with the perl version

you're lost in a twisty maze of regex flavors, all different

wheat ridge Mar 29, 2020, 2:43 PM

Hey! I use git bash for Windows and I'd like to make a bash script that I can use in my terminal that automatically cd's into a specific directory (predefined in the script) and then does ls -a. Would this be an alias, or can I make a specific script for it, and if so, how does that work when Windows is in the mix (even though I'm not using the windows command prompt?)? Even just some search keywords would be really helpful, as I'm not sure what the terms are for this concept

main olive Mar 29, 2020, 2:44 PM

#

easily implemented as an alias

wheat ridge Mar 29, 2020, 2:44 PM

#

That's what I was thinking too, although I would be open to making a script specifically for it just for the hell of it too, as I've never written a .sh script

#

How do aliases work in git bash for windows? Is there even a .bashrc? I barely remember how they work in unix, tbh... lol

main olive Mar 29, 2020, 2:45 PM

#

cd in a script doesn't work when running the script in a regular manner (ie sh script.sh) because it creates a new shell when the script is run and the cd only applies there - you'll have to source the script instead (source script.sh or . script.sh)

wheat ridge Mar 29, 2020, 2:46 PM

#

Oh interesting, I didn't know that!

main olive Mar 29, 2020, 2:46 PM

#

obviously the latter means you can't have the script in your PATH and run it anywhere, since you need to call source with a path to the file

wheat ridge Mar 29, 2020, 2:46 PM

#

Then an alias implementation would be far better for this particular thing

main olive Mar 29, 2020, 2:46 PM

#

so an alias is probably the easiest method

wheat ridge Mar 29, 2020, 2:47 PM

#

Okay, well that's enough information for me to do this then, thanks for the tip on sourcing, I didn't know that!

main olive Mar 29, 2020, 2:48 PM

#

of course, you can utilise both: have a script in a predefined location (like ~/.local/bin/script.sh) and an alias which sources it: alias dothething='source ~/.local/bin/script.sh'

wheat ridge Mar 29, 2020, 2:48 PM

#

Oo that's a good idea too

#

It probably fits just into an alias though, as it's suuuper simple. It's just cd'ing to the directory my dev project is currently in, then doing an ls -a and I might have it also start up my django server (I'm building a django local network website/server to be hosted on a raspberry pi)

main olive Mar 29, 2020, 2:50 PM

#

yeah, sure, makes sense

#

@wheat ridge also, yeah, git bash should have a bashrc in the regular location, $HOME/.bashrc, should work fine on windows

wheat ridge Mar 29, 2020, 2:53 PM

#

wtf this git bash doesn't have tree? Ahhgh no 😦

#

Oh, looks like past me has already made some aliases and forgotten about them lol

main olive Mar 29, 2020, 3:06 PM

#

there's a lot of aliases in .bashrc that come by default

wheat ridge Mar 29, 2020, 3:06 PM

#

No, they're definitely mine lol

#

I'm in bash_profile actually, which is where git actually recognizes aliases between sessions (.bashrc doesn't seem to work properly)

hello, so I've been learning python for around 4 months now.

But I'm bored of just doing python so I started learning linux command line and sql.

Do you guys think it's a good idea to learn multiple things at once?

#

Or should I just focus on python for now?

how can i launch to linux live usb with radeon mode? it always gets stuck on logo for me.

radiant pike Mar 31, 2020, 2:26 AM

#

So, this is a bit separate from python exclusively, but I'm trying to build something from source on Raspbian, and I'm running into a wall:

The thing I'm building depends on a patched version of x264. I've been able to compile the patched x264 version, but I've not been able to compile the overall library.
I've tried searching, moving files, recompiling, etc., but I still haven't been able to get ./config to find the patched version of x264 it depends on.
Can anyone help with this, and is this the right place to ask?

#

I should probably include that I'm following https://libdrc.org/docs/installation.html to compile from source

fickle granite Mar 31, 2020, 2:41 AM

#

@radiant pike try ./config --help, sometimes there's useful hints

#

often you have to do something like ./config LD_FLAGS=-lyour-library LDPATH=/where/ever/you/installed/it CXXFLAGS=-I/where/ever/you/installed/etc

radiant pike Mar 31, 2020, 2:48 AM

#

What's a good way to tell where I might've installed something?

#

When I ran make on the patched x264 lib, I don't know where the actual bins went

fickle granite Mar 31, 2020, 2:50 AM

#

heh

#

couple ideas

#

run make -n install and see where it says it's doing

#

other idea: list every single file on the file system, sorted by timestamp; the installation files will probably be recent, and all together

radiant pike Mar 31, 2020, 2:51 AM

#

I'm pretty sure it'll say x264.h not found

#

also I'm not good enough at bash to know how to list files by dir

#

or wait no it won't make, it'll ask for config first?

fickle granite Mar 31, 2020, 2:52 AM

#

well, if you ran make and it installed some stuff, run from that directory

radiant pike Mar 31, 2020, 2:52 AM

#

I'm assuming too much here, should try that

#

sorry

fickle granite Mar 31, 2020, 2:53 AM

#

I think this will search your whole file system -- it could be slow

#

find / -printf '%T@ ' -ls | sort -n | cut -d\ -f 2-

#

requires GNU find but that's probably what you have

radiant pike Mar 31, 2020, 2:53 AM

#

It's a fresh raspbian install, so the search shouldn't have to go far

#

it's erroring at cut:
cut: the delimiter must be a single character...

#

I'm not sure lemme retype

fickle granite Mar 31, 2020, 2:55 AM

#

try cut -d' '

#

you need two spaces after that \ btw

radiant pike Mar 31, 2020, 2:56 AM

#

with both the two spaces after and the ' ' it stops at no such file or directory with -printf and %T@

#

So I don't have somehting installed?

fickle granite Mar 31, 2020, 2:56 AM

#

you're mistyping something

#

or else you don't have GNU find, but I think you should

#

$ find --version
find (GNU findutils) 4.7.0

radiant pike Mar 31, 2020, 2:57 AM

#

got it, it was a space in /printf between the slash

#

it's going

fickle granite Mar 31, 2020, 2:57 AM

#

that recipe is super handy; I use it all the time

radiant pike Mar 31, 2020, 2:58 AM

#

It's going into the raspbian install files and listing things from 2018

fickle granite Mar 31, 2020, 2:58 AM

#

did I mention you should pipe the output into less? 🙂

#

also the interesting stuff is gonna be at the end

radiant pike Mar 31, 2020, 2:58 AM

#

is it going old to new?

fickle granite Mar 31, 2020, 2:58 AM

#

ya

#

you could flip that around by saying sort -rn instead of sort -n

#

probably ought to, now that I think about it

radiant pike Mar 31, 2020, 2:59 AM

#

so I piped it into less

#

I think less is working but I can't ctrl+c out of it

#

I'm pretty new to bash, no idea how to get out of this

#

ah ctrl z works I guess

#

Still not able to see the first entries it hits

fickle granite Mar 31, 2020, 3:02 AM

#

yep, I don't know why but sometimes C-z works when C-c doesn't

#

well try again, with sort -rn

#

it should be faster

radiant pike Mar 31, 2020, 3:03 AM

#

There's a lot of "no such file or directory" before it gets to the recent files
yeah, 've been doing the -rn sort for a bit

fickle granite Mar 31, 2020, 3:04 AM

#

huh

radiant pike Mar 31, 2020, 3:04 AM

#

Other than playing ctrl z whackamole, and trying to capture the absolute most recent files, how should I get the output from this to a reasonably readable format

fickle granite Mar 31, 2020, 3:04 AM

#

I could understand permission denied, but no such file or directory seems wrong

radiant pike Mar 31, 2020, 3:05 AM

#

here's an example line:

fickle granite Mar 31, 2020, 3:05 AM

#

try | head instead of | less -- that'll show the first 10, then stop

radiant pike Mar 31, 2020, 3:05 AM

#

find: /proc/63/exe: No such file or directory

fickle granite Mar 31, 2020, 3:05 AM

#

oh that's OK

#

those files come and go quickly

radiant pike Mar 31, 2020, 3:06 AM

#

I'd only get those though were I to do |head

#

right?

fickle granite Mar 31, 2020, 3:06 AM

#

uh no?

#

you can hide the errors with find / -printf '%T@ ' -ls | sort -rn | cut -d\ -f 2- 2> /dev/null | head

#

you could also try limiting to /usr instead of /, on the assumption that everything got installed under there

#

fewer weird files under /usr

radiant pike Mar 31, 2020, 3:08 AM

#

by doing find /usr -printf '%T@ ' -ls | sort -rn | cut -d\ -f 2- 2> /dev/null | head?

fickle granite Mar 31, 2020, 3:08 AM

#

ya

#

find is pretty complex but very useful

radiant pike Mar 31, 2020, 3:08 AM

#

ok that's less than a second to run in /usr

fickle granite Mar 31, 2020, 3:08 AM

#

but did it find your stuff?

radiant pike Mar 31, 2020, 3:09 AM

#

it found some codecs and drivers I knew were installed earlier

fickle granite Mar 31, 2020, 3:09 AM

#

well anyway; that's how you scour the whole filesystem

radiant pike Mar 31, 2020, 3:09 AM

#

Better than manually cd cd cd cd

#

and guesswork

fickle granite Mar 31, 2020, 3:10 AM

#

so here's a third idea: you might be able to go back into the directory where you ran "make install", and run ... make uninstall.

#

Not every package lets you do that, but this one might

radiant pike Mar 31, 2020, 3:11 AM

#

I linked the package earlier, right?

fickle granite Mar 31, 2020, 3:11 AM

#

dunno

#

my short-term memory lasts about two minutes

radiant pike Mar 31, 2020, 3:11 AM

#

For the specific package though, the actual main code has @echo TODO as it's uninstall

fickle granite Mar 31, 2020, 3:11 AM

#

heh

radiant pike Mar 31, 2020, 3:12 AM

#

The codec might be different though

#

the x264

#

it's based on existing stuff but patched

#

ok so I ran sudo make uninstall in the dir for the souce for that patched standard x264

#

and it removed two files

#

so, reinstall and try to point ./configure to those files?

fickle granite Mar 31, 2020, 3:14 AM

#

I guess

#

I'm actually having trouble picturing what you're doing

#

you're building two things from source, one of which depends on the other?

radiant pike Mar 31, 2020, 3:15 AM

#

yes

fickle granite Mar 31, 2020, 3:15 AM

#

yeah, try to do that

#

those files -- what were they? Two isn't very many

radiant pike Mar 31, 2020, 3:15 AM

#

the commands it ran were:

#

ah I was mistaken

#

two lines, 5 files?

#

Time for a crude screenshot

fickle granite Mar 31, 2020, 3:18 AM

#

you can't copy the text from your terminal?

radiant pike Mar 31, 2020, 3:18 AM

#

Hopefully useful

📎 JPEG_20200330_231747.jpg

#

the terminal's on a rpi and it's running a cli-only install rn

#

Tried getting a gui up but I'd get a login screen that when I put the right usrname and pass it'd just reboot

fickle granite Mar 31, 2020, 3:19 AM

#

that's an odd location -- I'd expect /usr/include instead of /include and /usr/lib instead of /lib

#

or even /usr/local/

#

the other thing you're building is probably not looking in /include, 'cuz that's weird. So I guess pass something like CXXFLAGS=-I/include to it

#

maybe CPPFLAGS instead

#

see what ./config --help tells you

#

yeah I think CXX is for C++, which I doubt you're using

radiant pike Mar 31, 2020, 3:20 AM

#

Would it be better to move this to a more sane location?

#

This is c++ source

fickle granite Mar 31, 2020, 3:20 AM

#

dunno tbh

#

you have to make the two packages "agree"; you can do that by fiddling one of them, or fiddling the other (or even both)

#

which is best is up to you

radiant pike Mar 31, 2020, 3:21 AM

#

I'm not sure what a sane location would be for this.
Here's what the install readme guides to do

#

I had to tweak this a bit to get it to work but it's here

git clone https://bitbucket.org/memahaxx/drc-x264/
cd drc-x264
./configure --prefix=$PATCHED_X264_PREFIX --enable-static
make install

#

and then to build the thing that depends on that:

#

cd libdrc
PKG_CONFIG_PATH=$PATCHED_X264_PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH ./configure
make```

fickle granite Mar 31, 2020, 3:22 AM

#

well $PATCHED_X264_PREFIX is a variable; what's its value?

radiant pike Mar 31, 2020, 3:22 AM

#

I've run env and it's not there

fickle granite Mar 31, 2020, 3:22 AM

#

maybe it's empty and that's why the stuff wound up in weird locations

#

do echo $PATCHED_X264_PREFIX

#

variables can live in the environment or just the shell; echo will look both places but env only looks in the environment

radiant pike Mar 31, 2020, 3:23 AM

#

blank/newline returned

fickle granite Mar 31, 2020, 3:23 AM

#

ok well that's why it got installed someplace weird.

#

the README probably assumed you wouldn't type $PATCHED_X264_PREFIX literally

#

I'd use /usr/local as the prefix; that's kinda conventional

#

My guess is that Mr Memahaxx is not super-professional in his documentation

radiant pike Mar 31, 2020, 3:25 AM

#

The website looks pretty professional :P

fickle granite Mar 31, 2020, 3:25 AM

#

and yet those two sets of commands you pasted are consistent, so it really shudda worked ...

radiant pike Mar 31, 2020, 3:25 AM

#

but good css does not a good readme make

#

https://libdrc.org/docs/installation.html

#

Here's where those commands appear if you want to look

#

I had a time getting git to clone from the bitbucket

#

Kept getting errors on the url other than not found

#

like, illegal url

#

I've started re-makeing the dependency lib

#

Looks like it's finding the dependency now, thanks

#

It's missing more dependencies, but at least it's a new problem

#

SDL and GLEW

fickle granite Mar 31, 2020, 3:33 AM

#

huh

#

💐

radiant pike Mar 31, 2020, 3:33 AM

#

do you know how to get SDL and GLEW?
"If you want to build the libdrc demos, SDL and GLEW are also required."

fickle granite Mar 31, 2020, 3:33 AM

#

I don't even know what they are

radiant pike Mar 31, 2020, 3:33 AM

#

so it's a problem of the docs

#

so from here it's a process of digging through the files to see what other dependencies are needed?

fickle granite Mar 31, 2020, 3:36 AM

#

yep

#

welcome to Open Source

#

and then struggling to build and install them

radiant pike Mar 31, 2020, 3:37 AM

#

them being those packages which have dependencies back to something that once ran on an 8bit micro or something

#

or are just really hard to find the dependencies for?

fickle granite Mar 31, 2020, 3:37 AM

#

dunno

radiant pike Mar 31, 2020, 3:38 AM

#

nono what did you mean by

and then struggling to build and install them

#

how far do dependency trees go

fickle granite Mar 31, 2020, 3:58 AM

#

heh heh heh

#

mua ha ha

radiant pike Mar 31, 2020, 3:58 AM

#

yep

#

I'm trying to build a new thing and

#

uhg

#

this is how open source works?

fickle granite Mar 31, 2020, 3:59 AM

#

BAAAAHAHAHAHAH HaHAHAA HA HA HHHHA AH snort HA HHA HAHAHA HA HAH HAH HAH HAHAH HAH HAH oh man HAH AH HAAAAAHAAAHHH cough cough cough hah hehhh hehhhhh geez.. cough

#

sometimes it's not this bad

#

but I think you're dealing with amateur software made by amateurs

radiant pike Mar 31, 2020, 3:59 AM

#

so it's build->need another dependency ->try to build -> need another dependency -> that has no docs

fickle granite Mar 31, 2020, 4:00 AM

#

it's usually not too bad, but yeah, it could go a few levels

radiant pike Mar 31, 2020, 4:00 AM

#

It's software with no release version

#

I found what GLEW is supposed to be

#

GL E Wrangler library

#

and I found it's github

#

it's saying now though:

#

this is something with make?

#

oh wait I might not need to build it

#

http://glew.sourceforge.net/install.html says there's premade .h and .c files for it?

fickle granite Mar 31, 2020, 4:04 AM

#

beats me

#

geez, it's hosted on sourceforge? In the 21st century? Good luck 😐

radiant pike Mar 31, 2020, 4:05 AM

#

:<

#

is sourceforge really that bad?

#

also the code's on github

fickle granite Mar 31, 2020, 4:06 AM

#

sourceforge notoriously starting inserting ads in windows executables that they hosted.

#

basically, corrupting the files that people had trusted them to host

radiant pike Mar 31, 2020, 4:06 AM

so, how do I resolve this issue in make:

📎 JPEG_20200331_0009342.jpg

#

ah, that's a google

fickle granite Mar 31, 2020, 4:16 AM

#

you've fumbled something. That glew directory somehow doesn't contain the source code

#

dunno what's in it

radiant pike Mar 31, 2020, 4:20 AM

#

The readme.mid has this gacha in it:

#

📎 unknown.png

#

There's a folder within called auto which requires you run make on it first ._.

#

running make there it's doing

#

something

#

about 10 screens of cmdline output later I have a tarminal again

#

I think they have a program which makes source

#

they've automated some part of the source writing process?

fickle granite Mar 31, 2020, 4:24 AM

#

wouldn't surprise me

radiant pike Mar 31, 2020, 4:24 AM

#

if they're hosting on sourceforge then anything's fair game, huh?

#

still getting "demos cannot be built because one of the dependencies (glew) could not be found"

hollow skiff Mar 31, 2020, 4:29 AM

#

Hey guys. I've created a bash file but when I try to open it with sudo ./adminMenu.sh it says ./adminMenu.sh command not found

#

Why isn't it running for me?

radiant pike Mar 31, 2020, 4:30 AM

#

Are you in the right directory when doing that command?

hollow skiff Mar 31, 2020, 4:30 AM

#

Yeah I can cat the file and see the script is in there too

#

Sorry I think it's a permissions problem

radiant pike Mar 31, 2020, 4:31 AM

#

so cat <file> works, but if you immediately run <file> it doesn't?

hollow skiff Mar 31, 2020, 4:32 AM

#

Yeah I chmod 744'd it and now I'm getting a different erro rlol

#

My mistake sorry

radiant pike Mar 31, 2020, 4:32 AM

#

ok, good luck with that

hollow skiff Mar 31, 2020, 4:32 AM

#

I think it was a permissions problem even with sudo

radiant pike Mar 31, 2020, 4:32 AM

#

Permissions to read from a directory?

#

But wouldn't cat fail then too?

hollow skiff Mar 31, 2020, 4:33 AM

#

I'm not sure. The file in terminal was white and normal font

#

Usually if you can execute it it's bold and a different colour right?

#

When i changed the mode it went to a different colour

radiant pike Mar 31, 2020, 4:34 AM

#

I'm honestly not well-versed in permissions in bash

#

But the different color sounds like a difference and like you're making progress for sure

#

also a different error

hollow skiff Mar 31, 2020, 4:48 AM

#

Yeah definitely progress

#

The format was just wrong in my script. A misplaced ;;

#

I'm trying to create a script that backs up files

#

But I want to copy only the files that have been edited since the previous backup

#

Any idea how I could go about that? 🙂

radiant pike Mar 31, 2020, 4:51 AM

#

I'd say follow the template of find / -printf '%T@ ' -ls | sort -n | cut -d\ -f 2- if I knew how it worked, but I don't

#

If you change n to rn then it shows files by date modified

#

and it shows them in recently modified first

#

so, that might be a building block you could use to find all files that were modified after some set date, and then copy them

#

so something like find / -printf '%T@ ' -ls | sort -rn | cut -d\ -f 2-

#

@hollow skiff This might work, but I'm not too sure how that command works. offby1 showed me that to find the most recently modified files

hollow skiff Mar 31, 2020, 4:54 AM

#

I typed that verbatim lol

#

But the %T@ is the path right?

radiant pike Mar 31, 2020, 4:54 AM

#

the path you want to start from is the /

hollow skiff Mar 31, 2020, 4:54 AM

#

I'm still very new so the conventions I don't know yet

radiant pike Mar 31, 2020, 4:54 AM

#

same

#

to start from /usr/local you'd do

#

find /usr/local/ -printf '%T@ ' -ls | sort -n | cut -d\ -f 2-

#

I don't know what '%T@ ' does

hollow skiff Mar 31, 2020, 4:56 AM

#

Okay, it's saying cut: the delimiter must be a single character

radiant pike Mar 31, 2020, 4:56 AM

#

there's two spaces at cut -d\ -f

#

between \ and -f

#

I did the same thing :P

hollow skiff Mar 31, 2020, 4:57 AM

#

Ahh ok. Now it's saying find: paths must precede expression: 'ls

radiant pike Mar 31, 2020, 4:57 AM

#

I've not seen that?

#

You didn't replace the %T@ at all did you?

hollow skiff Mar 31, 2020, 4:58 AM

#

find /var/www/html/intsite -printf '%T@ ' ls | sort -rn | cut -d\ -f 2-

#

That's what I have so far

radiant pike Mar 31, 2020, 4:58 AM

#

add a slash after intsite

hollow skiff Mar 31, 2020, 4:58 AM

#

Same error. Hmmmm

radiant pike Mar 31, 2020, 4:59 AM

#

is the var directory a home directory?

#

or should you use ./var etcetera

#

oh it is

#

should work

#

hm

#

oh you left out the - at -ls

hollow skiff Mar 31, 2020, 5:00 AM

#

Wwooow

#

I mean woo

#

Thanks !

radiant pike Mar 31, 2020, 5:00 AM

#

Is it working?

#

If you know how to use the output of that for a backup script then props to you

hollow skiff Mar 31, 2020, 5:01 AM

#

I don't lol. That's my next task

radiant pike Mar 31, 2020, 5:01 AM

Hey

#

What is a linux that you would recommend me?

#

linux is just the kernel :) there is no "a linux", it's the linux

#

think you mean a linux distro, which is an operating system distribution using the linux kernel

steel verge Mar 31, 2020, 8:08 AM

#

@main olive Whichever distro you like

main olive Mar 31, 2020, 8:08 AM

#

in which case, it depends entirely on your skill level

#

there's so much choice that it's a matter of taste at this point

#

but newcomers usually use Ubuntu or Mint

#

arch?

#

What is it like?

#

it is for people who already know their way around linux and are very comfortable with the terminal

#

xx

#

arch is very bare-bones, which is perfect for people who want to build their distro up to be comfortable to them

#

yes?

#

I want to install a linux distro without usb

#

Can you please check the internet about UNETBootIN for me?

#

what

#

you have the internet

#

I know but I'm really bad at these kind of stuff

#

also unetbootin is not for network boot

steel verge Mar 31, 2020, 8:12 AM

#

If you cannot use a USB stick, does your computer support PXE? Could boot from that, however, it is 100x harder to set up

you will not learn these things unless you research them yourself

@steel verge similar project, have you heard of DriveDroid? Emulates an USB drive and lets you boot ISOs stored on the phone

steel verge Mar 31, 2020, 8:19 AM

#

During a network boot, the computer fetches an IP from a DHCP server. The DHCP server will also deliver option 66 and 67, which are the filename to download and the server to contact for that file. The file is a bootloader, which is then booted by the OS and handles the rest of the downloads required.

Network booting, or booting from LAN as it is also called, is a process which allows a computer to start up and load an operating system or other program directly from the network without any locally attached storage device, like a floppy, CDROM, USB stick or hard drive.

So it loads?

It doesn't install?

Just put out the question

modern kestrel Mar 31, 2020, 3:19 PM

#

okay so i have a script that im running but it only works when i do

. ./upload-helm-chart.sh && setVariablesExecuteAll atlas eng

it works

#

but ./upload-helm-chart.sh && setVariablesExecuteAll atlas eng

#

it doesn't

#

so i'm confused why

warped nimbus Mar 31, 2020, 3:20 PM

#

What's the difference?

#

I don't see it

modern kestrel Mar 31, 2020, 3:20 PM

#

the . at the start

#

is it because my terminal is zsh?

#

im using iterm2

#

but ./upload-helm-chart.sh setVariablesExecuteAll atlas eng

#

sorry that doesnt work

#

the source/. and the && is missing

#

but usually if i want to run a function from a script ./testScript.sh testFunction arg1 arg2

#

works fine

#

know what i mean?

warped nimbus Mar 31, 2020, 3:23 PM

#

What about it doesn't work?

#

Oh you're trying to run a function within the script?

modern kestrel Mar 31, 2020, 3:23 PM

#

yep

#

function setVariablesExecuteAll {
path = $1
url = $2
}

#

trying to run this

#

. ./upload-helm-chart.sh && setVariablesExecuteAll atlas eng this works

#

./upload-helm-chart.sh setVariablesExecuteAll atlas eng

#

this doesnt

#

why? no idea

warped nimbus Mar 31, 2020, 3:24 PM

#

Cause I don't think it's supposed to work

#

I don't know where you got the idea that it should

#

If you want to use a function defined in a script you need to source it

modern kestrel Mar 31, 2020, 3:25 PM

#

because ive used scripts before where i can call a function like that and a lot of answers online say it should work

#

okay can you explain that please

#

i dont get the distinction

warped nimbus Mar 31, 2020, 3:26 PM

#

./script.sh arg1 arg2 executes a script with those args

#

source ./script.sh will instead like put the current script's commands in the current shell, if that makes sense. Not sure how to explain it well.

#

The source would make the commands defined inside the script accessible locally too i.e. outside the script and in the current shell

#

In this case ./upload-helm-chart.sh setVariablesExecuteAll atlas eng, as far as I know, the shell just interprets setVariablesExecuteAll as $1. So unless you have some code to call a function based on the value of $1, it won't do anything

#

This is how I understand it

#

Maybe zsh is different?

#

Can you link some of the answers that say it should work like that?

modern kestrel Mar 31, 2020, 3:29 PM

#

oooooooh

#

yeah i will

#

okay as soon as you said it registers it as a first argument

#

it seems so dumb that people are saying that

#

but thank you for that explanation

warped nimbus Mar 31, 2020, 3:30 PM

#

Yeah most answers say to source it

#

One answer uses "$@"

#

Which would do what you want

#

So yeah if you just add that to the end of your script it will work like you originally wanted

modern kestrel Mar 31, 2020, 3:31 PM

#

rightttt

#

yeah okay got you thanks Mark!

warped nimbus Mar 31, 2020, 3:31 PM

#

You're welcome

main olive Mar 31, 2020, 3:49 PM

#

source ./script.sh will instead like put the current script's commands in the current shell, if that makes sense. Not sure how to explain it well.
@warped nimbus it can be viewed like an import for shells

warped nimbus Mar 31, 2020, 3:49 PM

#

Yes! good analogy

main olive Mar 31, 2020, 3:50 PM

#

much more primitive, but the core concept is the same

modern kestrel Mar 31, 2020, 3:50 PM

#

yeah it makes sense to me now xx

#

does that mean source makes it run it first then? so it will run twice effectively

main olive Mar 31, 2020, 3:53 PM

#

source does execute stuff in there, but if you've defined a function, only the "defining" itself will be executed, not the body of the function itself

#

if that makes sense

modern kestrel Mar 31, 2020, 3:56 PM

#

okay it makes sense

#

ill take it for what it is and not pry further at risk of confusing myself lol

Is it possible to run a Selenium chrome driver on Ubuntu just with putty? Because it can't open any page visually or else

main olive Mar 31, 2020, 4:19 PM

#

that's pretty much the point of selenium, that it doesn't require a graphical interface

tidal lark Mar 31, 2020, 4:20 PM

#

Okay well, because when I deployed it on my windows machine it didn't give me any errors but now on my server it does. However, good to know that it is possible. Thanks

main olive Mar 31, 2020, 4:21 PM

#

what errors exactly?

#

might be able to help or point in the right direction

#

also my apologies, i've been misleading

tidal lark Mar 31, 2020, 4:22 PM

#

wdym

main olive Mar 31, 2020, 4:23 PM

#

selenium itself doesn't require a graphical interface, but whatever browser you're using for the backend might. for this, you have to be sure that selenium tries to use chrome headless

tidal lark Mar 31, 2020, 4:23 PM

#

Oh okay

Discord has support for Markdown, which allows you to post code with full syntax highlighting. Please use these whenever you paste code, as this helps improve the legibility and makes it easier for us to help you.

To do this, use the following method:

```python
print('Hello world!')
```

Note:
• These are backticks, not quotes. Backticks can usually be found on the tilde key.
• You can also use py as the language instead of python
• The language must be on the first line next to the backticks with no space between them

This will result in the following:

print('Hello world!')

#

can you link us to the jenkins job?

modern kestrel Apr 1, 2020, 11:11 AM

#

hmmm its in a vpn

#

you mean the jenkinsfile code?

main olive Apr 1, 2020, 11:12 AM

#

sure

#

what script it's trying to run exactly

modern kestrel Apr 1, 2020, 11:12 AM

def THE_ENVIRONMENT = "eng"
def PATH_FILE = "atlas-logs-exporter"

    agent any

                }
            }
        }
    }

#

this one

#

oh the script is something else

#

its running the helm chart script

main olive Apr 1, 2020, 11:12 AM

#

are you defining functions in the script with function?

modern kestrel Apr 1, 2020, 11:13 AM

#

yup like this

#


path=$1
url=$2

function createHelmTemplate {
  if [ ! -z "$path" ]; then
    out=$(helm template --namespace test --values=values.yaml --set id=test -x $path . )
  else
    out=$(helm template --namespace test --values=values.yaml --set id=test . )
  fi
  echo "${out}"
  helm lint --namespace test --values=values.yaml --set id=test . && \
  echo "${out}" | kubectl apply --validate=true --dry-run=true -f -
}

#



function executeAll {
  cd "$path"
  createHelmTemplate
  packageHelmTemplate
  loginToVault
}

function executeLint {
  cd "$path"
  createHelmTemplate
}

main olive Apr 1, 2020, 11:13 AM

#

sh doesn't support that syntax

modern kestrel Apr 1, 2020, 11:13 AM

#

this is the execution

main olive Apr 1, 2020, 11:13 AM

#

use createHelmTemplate() { stuff } instead

modern kestrel Apr 1, 2020, 11:14 AM

#

for all of them?

#

add the ()

main olive Apr 1, 2020, 11:14 AM

#

add the (), and remove the function

#

and yeah, all of them

#

#!/bin/sh

function()
{
  echo "args: $@"
}

something lik ethis

modern kestrel Apr 1, 2020, 11:19 AM

#

yep gotcha ill let you know what happens

#


. ./upload-helm-chart.sh atlas-logs-exporter && executeLint

<1s
+ . ./upload-helm-chart.sh atlas-logs-exporter

+ executeLint

+ [ ! -z  ]

+ helm template --namespace test --values=values.yaml --set id=test .

Error: open values.yaml: no such file or directory

+ out=

script returned exit code 1

#

Now that comes up

main olive Apr 1, 2020, 11:22 AM

#

well, it can't find values.yaml for whatever reason

#

can you add a pwd right before that last command and see where it's trying to run from?

#

and whether it's the same directory where values.yaml actually is

modern kestrel Apr 1, 2020, 11:23 AM

#

okay

main olive Apr 1, 2020, 11:26 AM

#

also i just realised

#

it does cd with no argument

#

looks like $path is blank

#

cd with no argument changes directory to the user's home dir

#

which on jenkins is some arbitrary location and probably not where you actually want to go

#

this is probably why it can't find values.yaml

modern kestrel Apr 1, 2020, 11:28 AM

#

okay yeah spoke w colleague

#

why might that be?

#

sh ". ./upload-helm-chart.sh ${PATH_FILE} ${ENG} && executeAll"

#

this is what jenkins runs

#

and we specify path as $1

#

url also isnt set

#

+ path=
+ url=
+ executeLint
+ cd 
+ createHelmTemplate
+ [ ! -z  ]
+ helm template --namespace test --values=values.yaml --set id=test .

#

grrrr

main olive Apr 1, 2020, 11:33 AM

#

i'm not sure the jenkinsfile does variable substitution like that

modern kestrel Apr 1, 2020, 11:33 AM

#

setVariables() {
path=$1
url=$2
}

#

hoping this fixed it...

#

okay didnt do shit

main olive Apr 1, 2020, 11:34 AM

#

oh, no, jenkinsfile does do that

#

strange

#

dunno, i'm stumped

#

haven't really worked with jenkins too much

modern kestrel Apr 1, 2020, 11:57 AM

#

okay ive narrowed down the issue

#


                    // Change environment and path file below
                    def THE_ENVIRONMENT = "eng"
                    def PATH_FILE = "atlas-logs-exporter"
                    if (env.BRANCH_NAME == 'master'){
                        if (THE_ENVIRONMENT == 'eng') {
                            sh ". ./upload-helm-chart.sh ${PATH_FILE} ${ENG} && executeAll" 
                        } else if (THE_ENVIRONMENT == 'ops') {
                            sh ". ./upload-helm-chart.sh ${PATH_FILE} ${OPS} && executeAll"
                        }
                    }

#

the issue is the defined variables arent being passed through

#

no idea why

main olive Apr 1, 2020, 12:33 PM

#

@modern kestrel did you ever figure it out?

#

a workaround i was going to suggest was using environment instead of defining them with def

modern kestrel Apr 1, 2020, 12:41 PM

#

i have a senior engineer looking at it and he's stumped too haha hes diagnosing it but bash isnt his forte

#

i was going to try that

main olive Apr 1, 2020, 12:51 PM

#

tbh i don't think this is a bash-specific issue

#

it seems (to me at least) to be related to jenkins

modern kestrel Apr 1, 2020, 12:59 PM

#

apparently path is a keyword

#

or something

#

idk still looking lol

#

think is his speciality is jenkins and he said the jenkins file looks fine

#

main olive Apr 1, 2020, 1:19 PM

#

what distinguishes Unix from other file systems?

#

@main olive Unix is not a file system

#

what other systems do you have in mind?

#

idk i just wanna know what unix even is

#

it's an operating system. Nowadays, it's more used as a philosophy that other operating systems (like Linux and MacOS) follow

#

which is why BSD, MacOS, Linux, etc have a lot of similarities

#

o ok

#

I'm rubbish at this sort of thing so that's helpful

#

yea

#

nowadays, when people say Unix, they don't actually mean "the Unix operating system", they probably mean something like Linux or similar

modern kestrel Apr 1, 2020, 2:47 PM

#

@main olive is was because the first argument was called path

#

in the script

#

changed that and it fixed

main olive Apr 1, 2020, 2:58 PM

#

coolio, good to know

#

and very obvious now that i think about it

#

$PATH has a special meaning

modern kestrel Apr 2, 2020, 10:49 AM

#

What's the difference between source and .

#

I'm not quite getting it

#

Some people say theres no diffrence but there definitely appears to be

main olive Apr 2, 2020, 10:59 AM

#

what differencese are you experiencing?

modern kestrel Apr 2, 2020, 11:31 AM

#

build passes with .

#

not with source

magic basin Apr 2, 2020, 12:11 PM

#

can you compile python code with the make command

livid verge Apr 2, 2020, 12:12 PM

#

yes... all make command does is run a bunch of commands from the Makefile

#

so all you have to do is write your Makefile with the commands you want to run

#

usually we use wheel and setup.py instead, though

magic basin Apr 2, 2020, 1:34 PM

Hi

#

How can i print a textfile in the console, but with timestamps of when each line of the file was written

main olive Apr 2, 2020, 1:59 PM

#

that information isn't stored on a per-line basis

#

you have the creation date and the last-modified date

#

you need to make it so whatever creates that textfile also prepends timestamps

magic basin Apr 2, 2020, 2:14 PM

#

here is my command
date +%A%_d" "%B", "%Y" @ " && echo $(date +"%r" | sed -e 's/$[0-9][0-9]:[0-9][0-9]$:[0-9][0-9]/\1/')

#

how can i get both the outputs onto the same line

#

that's my issue
