can someone help?

docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: "jupyter": executable file not found in $PATH": unknown.
the container element works, but the jupyter launch fails
i have integrated jupyter into my paths
to be specific, i have added the jupyter launch directory to my PATH system variable
and i can launch jupyter by executing 'jupyter notebook' in the cmd terminal
main olive
the system's $PATH does not carry over to docker
you might have to point directly to where you think the jupyter binary is in the container with an absolute path
left pilot
i see, do you know how i would locate the jupyter binary?
main olive
is there any reason you're using that particular image and not something like https://hub.docker.com/r/jupyter/tensorflow-notebook ?

I know how to ping an ip or resource
but how do you ping an ip through another ip
master (where I am) --> worker IP ---> another IP
I want to check whether the worker can reach the other ip
modern kestrel
ssh into it?
main olive
I can't ssh.. the network rules don't allow it
ssh to worker I mean
unless the "worker" is set up for forwarding packets, what you're describing is impossible
modern kestrel
then modify so you can
main olive
forwarding packets?
yes, so that the worker forwards the ping packet to the other IP and the response back to you
oh
hmmmm
how do I check workerIP-->another IP connectivity then

normally to execute i just run python3 get_token.py in that directory
anyone?

@main olive does your script start with .

@modern kestrel I figured it out now, thanks!
i had default python when i needed python3

if so then

Is there a command of the os module to know how much RAM has a computer? On linux

doubt it
you could run a command like "free" and parse the output; there are probably 3rd-party libraries that do the equivalent of that.
I'd guess "ansible" has something like that, but that's not a library; it's a complex application

small kraken
anyone got experience running a python script as a systemd unit? I'm trying to run my discordbot through it, and it's sort of working but the logging isn't working the way I want it to.
The bot uses print(stuff) to output things like who executed what command etc, and it has ascii escapes to colorise the output.
But there are two issues when running it through systemd:
- output is only captured by journalctl when the server restarts
- my fancy color coding isn't visible
[Unit]
Description=MrFreeze (beta)
After=network.target
[Service]
User=mrfreeze
Group=mrfreeze
WorkingDirectory=/srv/mrfreeze
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=MrFreeze
ExecStart=pipenv run bot
[Install]
WantedBy=multi-user.target
I first did it without the standardoutput things but it doesn't seem to matter.
so when it's restarted everything that it should've outputed is outputted as if it was just printed, with the time stamp saying the current time, rather than continously printing it.
main olive
have you considered using the logging module instead of just prints?
it will make your life a fair bit easier
small kraken
what does it do?
small kraken
how is it different from just printing?
main olive
you have different logging levels, can apply filters, don't need to necessarily log to stdout, etc
it's far, far more powerful than just printing
you can also decouple the log messages from the actual format
so if you ever want to change anything regarding how your logs are printed, nothing breaks
small kraken
hm, I will look into it. I think almost all logging already goes through a logging cog (sort of a module in discord.py) so it should be easy to change

you typically load your driver as a kernel module if it's external

fi
hmmm for the most part yeah my job wasn't to understand the whole thing but i was trying to modify this script so it would take in the chart and path and then execute the functions
we got too stuck so our tech lead quickly did it this way
but we have no idea what he has done we dont understand bash very well lol
and he is too busy to explain ๐ฆ
okay let me think about that for a few minutes please ๐
what i dont understand there are several things
robust cave
if [ "$#" -lt 2 ]; then
echo "Usage: URL DIRECTORY [--dry-run]"
else
this checks if the number of arguments are less than 2, and if so echo the help message
chart_museum_url=$1
the_path=$2
pushd $the_path
this sets chart_museum_url to the first argument, the_path to the second argument, and pushes the_path to the top of the directory stack
pushd: https://unix.stackexchange.com/questions/77077/how-do-i-use-pushd-and-popd-commands
for anything related to helm, the relevant documentation is here: https://helm.sh/docs/
I'm not familiar with it
if [ "$#" -eq 2 ]; then
packageHelmTemplate $chart_museum_url $the_path
fi
this then passes chart_museum_url and the_path to packageHelmTemplate if the number of arguments to the script is exactly 2
robust cave
np
robust cave
what do you not understand?
modern kestrel
if there is less than 2 arguments it will echo an error but otherwise why does it need the -eq 2
there will only be 2 arguments max
i dont see why the second if statement is there thats all
seems overdone
robust cave
I have no idea about the reasoning, but you can pass more than 2 arguments to the script, it just won't execute this block:
if [ "$#" -eq 2 ]; then
packageHelmTemplate $chart_museum_url $the_path
fi
yeah thats why im confused bercause the jenkins file will only pass 2 arguments max
maybe this is just an additional precaution
but thanks that helped ๐

Hi can i set a max login timeout of 10 minutes so when i login, i can do whatever i want and as soon as it's been 10 minutes i get disconnected, no matter what i am doing
or maybe 1 minute before it i can run a script that will show i have not much time left
So:
System starts timer for 9 minutes and 10 minutes
When the 9 minutes is up, runs a bash script that tells them they have not much time left
When the 10 minutes is up, the user is disconnected
How would i do this
fickle granite
you might be able to have a program that a) starts when you log in; b) counts down the alloted time; c) kills all your processes
but that'd be messy
like if you had a cron job running by coincidence, it'd kill that too
in theory you might be able to find all your login processes, and then kill them and their children, but ... eww
more than you ever wanted to know: https://www.gnu.org/software/libc/manual/html_node/Job-Control.html#Job-Control
lavish hemlock
I tried making a python script that does it but it just waits for the 10 minutes, and i am unable to do anything, i would need to run it on startup as a background process
fickle granite
well you can start it reasonably easily by putting something in your ~/.bash_profile or whatever file your shell reads at startup
lavish hemlock
Yes but it will do the same thing
there's TMOUT=x
but when you're running python programs it will pause
fickle granite
I didn't understand a word of that, tbh
lavish hemlock
So i can add TMOUT = 10 to the .bashrc file
which will terminate my session after 10 seconds
that is what i want
but let's say i start a python program and go inactive, it will not terminate my session
if i use the w command, it will still show the amount of time i am idle though
@fickle granite
fickle granite
well I never knew about TMOUT so I don't have anything to say about that
lavish hemlock
is there anything i can do about the w command
fickle granite
well you could have a python program figure out your idle time, I guess
fickle granite
I wouldn't be that surprised if there were, tbh
lavish hemlock
Ok after a little research, there is a way to do it with the /etc/ssh/sshd_config file itself. All you do is add:
ClientAliveInterval 300
ClientAliveCountMax 0
So i guess it's good if you forget to log out of the root user while you grab a coffee :D
fickle granite
if that does what you think, then it should be reliable

how do I pass the password here
main olive
anyone?
this is what I'm trying to do
echo $(gcloud auth print-access-token)\n$(gcloud auth print-access-token) | myapp docker-registry update 22 -u oauth2accesstoken```it's not an arg.. because it doesn't have -p flag or accept --password stdin
it prompts for password.. then you type and press enter.. then prompts to reenter password once more
main olive
@main olive
test your output first before piping it
I tried this
and I am not sure if it entered the password into the prompt.. because I had to press enter both times
@main olive
you might need to use expect or similar
the application might be devouring stdin
could you give me an example
is it like this
#!/bin/bash
export PATH=$PATH:/root/bin/
gcloud auth activate-service-account myid@my-project.iam.gserviceaccount.com --key-file=gcrconnect.json
myapp docker-registry update 22 -u oauth2accesstoken
expect <<- DONE
expect "Password:"
send "$gcloud auth print-access-token\r"
expect "Retype password:"
send "gcloud auth print-access-token\r"
expect eof
DONE
I tried this: but still having trouble
#!/bin/bash
export PATH=$PATH:/root/bin/
gcloud auth activate-service-account myacc-gcr@project.iam.gserviceaccount.com --key-file=gcrconnect.json
auth_token=$(gcloud auth print-access-token)
expect -c "
spawn myapp docker-registry update 22 -u oauth2accesstoken
expect "Password: "
send "$auth_token\r"
expect "Retype password: "
send "$auth_token\r"
"
DONE
It works.. I'm done with this problem now
can someone tell me how export PATH works and why we need path variables
like I want to understand what's going on here
with PATH
does it overwrite the first one
main olive
export PATH just means that PATH is turned into an environment variable, rather than just a bash variable
aka all child processes inherit it
"does it overwrite" no, because each time PATH is set, the old PATH is included in it
aka it appends instead
PATH=/root/bin would overwrite, while
PATH=$PATH:/root/bin appends to the old path

Hello, I need to check if I have PyQt5 installed via which and for some reason it is not showing up although I have it installed. I thought it is because it is pip3 module, but when I do eg. which pyinstaller that one shows up. Does anybody know what could be the reason behind that? To understand, why I would like to prefer which, I am checking more executables and I do that with for loop.
main olive
@main olive you're welcome.
@frigid needle does pyqt5 even provide executables? what command are you using?
frigid needle
@main olive I am using which pyqt5
main olive
which only points to the location of executable binaries on $PATH
pyqt5 isn't one, it's the name of the pip package
you'll need to use something like pip show pyqt5

Many thanks. I already considered using pip show pyqt5, but wanted to use which, if there was a way.
warped nimbus
Which is for executables that are on discoverable on your PATH environment variable
If pyqt5 doesnt come with executables then you cannot use which for it
It actually does have some executables IIRC, but not one named.pyqt5
There's one for generating ui files from python, but I don't remember the name
If you want to see if it's installed you could just use pip
"Pip show pyqt5"
Or you can grep "Pip list"
Oh that's been mentioned already

oh, then your terminial is using a font that is incapable of displaying that charcter.

this has nothing to do with python; it's to do with your terminal app, and/or the font it's using

lavish hemlock
what do you use?
fickle granite
Mac
fickle granite
you have some other process running apt
if you're certain that you don't, then I think you can delete that lockfile
the file probably contains the PID of the process that created it
find that PID, then see if the process is still running
if not, it's fine to delete the file
if so, you should try to gracefully kill the process

Hi everyone! Iโm using Ubuntu 16.04 and when I open the terminal the username takes too much time to appear, what can I do?
What else can I provide?
chilly mural
Have you checked if it is system related? ie. slow hardware. What terminal emulator are you using. I'm assuming the default terminal, but that's not a guarentee. Have you searched for this problem on google and tried any of the soltuions provided there? Did they make a difference? or did they fail? What else have you tried
Is it just the name that takes time to appear or does the entire terminal stall? how much time is too much time? are we talking seconds, minutes, years. does the terminal work fine after the name appears if it doesn't work while the name loads?
To start I would recommend following this https://stackoverflow.com/questions/5014823/how-to-profile-a-bash-shell-script-slow-startup to check if your load times are caused by something in your bashrc file. If you're using the non-default terminal emulator you might look at the FAQ or similar for slow startup questions as there can be workarounds there. LMK if you have any further questions/need help
lavish hemlock
why does the terminal sometimes disconnect when i use ctrl+z
chilly mural
what do you mean by disconnects? Also ctrl+z is generally used to suspend a proccess in the terminal
so if you're running a command and you use ctrl+z it should pause running that command
lavish hemlock
well i didn't get disconnected, but the terminal went black and i couldn't do anything else after that
not even ctrl+c worked
chilly mural
ctrl+d?
tribal pewter
@chilly mural
Well thank you very much! I am not the only using that computer and turn out somebody created a conda enviroment, I followed your advise about the .bashrc timing so:
Before:
chilly mural
Conda will do that XD. NVM is also a common offender. I'm having ~.5s delays from bash-complete+/NVM that I'm working on solving. LMK if you have any other bash related questions
tribal pewter
time source .bashrc
real 0m5.263s
user 0m5.770s
sys 0m2.011s
then i look for the bashrc and deleted the conda init part:
`#Anaconda PATH
export PATH=~/anaconda3/bin:$PATH
>>> conda initialize >>>
!! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/home/manuel/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
eval "$__conda_setup"
else
if [ -f "/home/manuel/anaconda3/etc/profile.d/conda.sh" ]; then
. "/home/manuel/anaconda3/etc/profile.d/conda.sh"
else
export PATH="/home/manuel/anaconda3/bin:$PATH"
fi
fi
unset __conda_setup
<<< conda initialize <<<`
After:
real 0m0.093s
user 0m0.078s
sys 0m0.016s
Then I check if everything was working fine and it did!
@chilly mural I checked in Google but I did not find an answer before

Yep, for the most part you'll wanna keep files in their respective places in the fs and everything else goes in the user's space. There's more to it than that, but that's what questions are for.

@main olive are you there?

I'm having problems with a server I use. The server has Ubuntu 18.04 and the problem is that some processes sometimes just get killed. It is configured with 256 MB of RAM so I don't know if that is the problem. On it, it's just a headless chrome selenium session that runs ( currently manually ). However, sometimes it works just fine and it gives me the data, sometimes it takes really long and eventually crashes and sometimes the process just gets killed before it does anything. Any suggestions?
main olive
what does the process output when it crashes?
256M might be a problem if you're doing selenium
try adding swap
tidal lark
Either the first or it tries to start and eventually crashes
main olive
hmmmm, not too much info here
I think you're onto something with the memory, though
add a gigabyte of swap and see if it crashes then
tidal lark
Do I have to configure it on the server hosts site then?
main olive
no, no, this is locally
tidal lark
Ok I will try that out, thanks
But just for the record: The problem is the RAM then, right?
main olive
easiest is to fallocate -l 1G /root/swap
and then mkswap /root/swap
and finally activating it: swapon /root/swap (this step doesn't persist and has to be done on each reboot unless you add it to /etc/fstab)
and see if free -m shows the additional gig of swap
and re: is it RAM
not sure, but this will help narrow it down
tidal lark
swapon: /root/swap: insecure permissions 0644, 0600 suggested.
swapon: /root/swap: swapon failed: Operation not permitted
chmod 600 /root/swap then
tidal lark
It gives me this error i.d it is a rented server
main olive
you seem to be root, so it shouldn't matter
tidal lark
Even with 600 I'm prohibited and that's what free -m says:
root@noez6414:~# free -m
total used free shared buff/cache available
Mem: 256 104 100 1 51 152
Swap: 16383 0 16383
Do you know what else could be the problem with selenium? I thought it only could be the RAM because sometimes it works fine
main olive
no idea, sorry, i personally haven't touched selenium at all
tidal lark
Okay but thanks for your help

is it possible to have something along the following lines
git add blah

yes commit can handle muti-line comments.
main olive
@digital haven try git commit without -m or the message and see what happens ;)
@chilly mural I'm here, what's up
digital haven
@main olive yeah i wanted to commit from a script though
main olive
sure, should still work
on the off chance it doesn't, replace EDITOR with a function which returns whatever your message is in the script
digital haven
if there's no message how will there be a message ๐ค seems a bit zen for me
digital haven
by from a script i mean - i will not type the message, the commit message will be scripted
main olive
pure speculation tbh
digital haven
fair, i don't think that it works
main olive
oh, right, it needs to write the contents to a temporary file, not return the message
digital haven
yeah, i wanted to write a multiline commit message from a script
single line is fine, but not sure how to do multi
just realised i had space around = and it's shell, let me check without
seems not
mkdir testing
cd testing
git init
echo "this is a file" > something.txt
git add something.txt
msg="this is a test
commit message"
git commmit -m $msg
that's the gist of it, i'll have to stick to one line
main olive
@digital haven works on my machine
digital haven
that's not from a script tho
main olive
that really shouldn't matter
digital haven
it shouldn't
main olive
it doesn't
digital haven
i tried one line with \n and it didn't work
main olive
you need to insert actual newline characters, otherwise nothing will parse \n
that's why I did $'\n'
digital haven
hmm ok
main olive
shell parses that into a newline character for me
digital haven
let me try that, thanks
main olive
also, in your script
in the commit line (the last line), try "$msg" with the quotations
digital haven
i always forget when i should/shouldn't quote vars
or maybe the advice is "always"
main olive
you always should
digital haven
๐คฆโโ๏ธ
main olive
unless you know you shouldn't
digital haven
fair, i don't use bash enough
main olive
like when you're passing a string as separate flags / arguments
digital haven
seems the way you did it works, i can't get others to though
this doesn't
all good, thanks
chilly mural
hey xx, I wanted to know if you had any advice on improving terminal launch times. I've got a couple of things in my .bashrc that slow everything down. NPM, bash complete, and some scripts I'm sourcing. My intuition says to lazy load them, but I donโt know if you can do that without using a subshell which kind of defeats the purpose. Iโve read about wrapping them in functions so they load when theyโre called. But then you'll have load times when you start them, which is better than every terminal instance. Is there another solution that loads then when there terminal starts, but doesnโt stall the terminal while the rest of the script is loading?
main olive
@chilly mural you know, I was literally just thinking about this the other day. I've got loads of crap in my rc that slows down shell execution on startup. These are mostly things that would load by the time I navigate to the correct directory anyways to utilise them, so it doesn't make sense that my entire shell spawning stalls while they load, especially if I eventually don't even end up using them. I've been devising a method to load them in the background, only blocking if you call something which relies on a thing which hasn't managed to load in the background yet (which I don't imagine would happen very often, but might still do in certain scenarios). I'll let you know if I've come up with something functional
I'm sure something like this already exists in some form, but I haven't been able to come up with the correct terms to find it on Google
chilly mural
I've done some extensive googling and couldn't find anything. Some people were talking about moving things from rc files to .profile, but I don't understand the difference between login/interactive and non-login/non-interactive shells to understand the value*

fickle granite
I can't honestly say they're useful because I don't have real data. They sure feel useful
The one I have for work couldn't be easier to use: it's small enough that it fits into a USB-A slot, and barely protrudes; a bunch of times per day I just touch it, and that's it.
I have one on my keychain for personal use, and once in a while when I log in to google or github or whatever, from a new machine, I have to stick that into the slot and touch it. I could just as well use the 2fa app on my phone for that, so ... ๐คท

@lavish hemlock SSH supports PAM, which in turn supports anything as long as someone has written a library for it - fingerprints, anus prints, password = username backwards, etc
although I'm not sure you even need PAM, doesn't SSH come with GPG support out of the box? (which most physical keys do)

python has it's own ways to deal with the filesystem rather than ls

you can tell it to do all kinds of stuff

git checkout <(git branch | grep -iE '^[ ]\w+/\w+/${1}/.*')
I get this error ```
fatal: /dev/fd/63: '/dev/fd/63' is outside repository at '/home/mark/repos/python/bot-pydis'
Any ideas why this process substitution is not working?
I can just use xargs for now

Do you ever just wish sudo service life stop was a command
main olive
@warped nimbus sure you want to be doing <() and not $()?
warped nimbus
You're right
I misunderstood the purpose of <()
The command doesn't read from files so that's why it wasn't working

Does PuTTY support coloured emoji's over SSH?
When i paste them they just turn into this:

I see people using custom fonts, but i don't have a graphical interface, only the console ^^
main olive
you can tell your terminal emulator to use whatever font
your terminal emulator is the "graphical interface"
even in a truly non-graphical interface such as a tty, you can still specify custom fonts (albeit probably not ones with unicode support)
lavish hemlock
How can i install the fonts in the terminal? @main olive

I tried that already @valid wasp , It is outdated and doesn't work for me

Uhhh. So I'm a noob. I managed to created a folder called "~" within another folder
how do I delete this without nuking my home directory?

hello! i want to know is it good idea to generate ctags through all virtual environment

I wouldn't think ctags would be useful at all in python

path+=/some/new/bin/dir && export PATH works but when i restart terminal it does not work anymore
im using zsh
dreamy wing
yeah you need to add it to your .zshrc file
tired relic
i tried that it didnt work
dreamy wing
did you use export PATH={yourpath}:$PATH
dreamy wing
Have you set zsh as your default terminal, if so and you are in zsh echo $PATH
tired relic
yes it ismy default terminal
when i add that line to my .zshrc file it doesnt work even without restarting terminal
dreamy wing
Yeah, the .zshrc file runs at the start of zsh. It should be permenant after that.
tired relic
ok i found something online that seems to work
dreamy wing
side note: get powerline10k
tired relic
powerline10k?
dreamy wing
look it up, if you are interested in looks
tired relic
thanks
main olive
when i add that line to my .zshrc file it doesnt work even without restarting terminal
@tired relic everything you put in.zshrcgets execute when zsh is started
if you edit something in there, you need to either source ~/.zshrc or exit and start zsh again
lavish hemlock
i made a script for adding stuff to path lol
i kept forgetting the command to do it
now i just have to type path
how fancy
ember moat
Is zsh better than bash? If so, how?
lavish hemlock
Idk, i have set my shell to a python program and there doesn't seem to be any method of bypassing it @ember moat
ember moat
I made a script for unzipping files with different extensions and it turns out that a very similar thing was in my .bashrc
lavish hemlock
why does source .bashrc work but bash .bashrc doesn't?
isn't .bashrc just a bash script?
native mesa
source <scritp> command u run in the current bash terminal that <script>
lavish hemlock
i know
fickle granite
"source" doesn't start a new process; instead it modifies the currently-running process
bash .bashrc "works", in that the new bash process gets all the customizations, but then guess what -- that new process exits as soon as it's finished reading .bashrc
so if .bashrc contains, say echo hello, and you "source" it, it's exactly as if you'd typed echo hello.
similarly, if it contains x=zebra, it's exactly as if you'd typed that; which means the shell you're now using suddenly has a variable named x, set to zebra.
main olive
Is zsh better than bash? If so, how?
@ember moat "better" is subjective. I like zsh more because it had far wider support for plugins and some of its syntax is more modern, asides other minor details like allowing null bytes in variables (making it entirely plausible to store binary data in variables and not just text)
lavish hemlock
@fickle granite But i get errors when running bash .bashrc
main olive
yes, because .bashrc is not meant to be run with bash. It's not a script.
like the error says:
$ bash .bashrc
.bashrc: line 8: return: can only `return' from a function or sourced script
you're not sourcing it...

I've broken my terminal
can someone help
if i try to use shortcuts
ls -(anon):4: command not found: _longopt โโโ 1 โ ๎ณ at ops โ
(anon):4: command not found: _longopt
(anon):4: command not found: _longopt
I get this
my auto suggest for kubernetes and gi
are still working fine its just the bash stuff
so confused

Same for this

_setup:64: bad output format specification
Same here
But some basic stuff still works like cat/nano
fickle granite
my guess is that you've got a "prompt command" that is doing something wrong; try echo $PROMPT_COMMAND ; unset PROMPT_COMMAND. If that helps, then you need to figure out how it got set, and how to fix it
modern kestrel
that doesnt seem to do anything
all i did was accidentally run some weird file accidentally
this thing
but i dont know how to undo that
i'm not even sure what the hell it is
sourcing my .zshrc file doesn't help either
main olive
dunno, just like .zshrc.bak
modern kestrel
and see if its the issue?
main olive
yeah
main olive
you need to restart your shell
modern kestrel
yeah its kind of fixed it but now its just shit
but if i do ls -[tab]
it doesnt give an error
now*
yeah its a problem with the zshrc thing
[[ ! -f ~/.p10k.zsh ]] || source ~/.p10k.zsh

alias k="kubectl"
autoload -U +X compinit && compinit
source <(kubectl completion zsh)
these are really the only custom things i have in here
plugins=(git kubectl)
source $ZSH/oh-my-zsh.sh
export ZSH="/Users/Shahe.Islam/.oh-my-zsh"
And these but theyve always been there
may just have to reinstall
main olive
hmm
autoload -U +X compinit && compinit
source <(kubectl completion zsh)
what if you remove these?
modern kestrel
weird that worked
autoload -U +X compinit && compinit
I think this line was messing it up?
No idea why i had it in there kubectl seems to be auto completing fine without it

Is there anyone that could help out with getting AppKit to install? I've tried pip and pip3 but it always returns with the same error. Trying to grab the active windows name
Here is the error
main olive
@simple hornet macos?
the error says it: pkg-config is not installed
you probably need to do something like brew install pkg-config
simple hornet
yeah macos
just got my first mac ever
and okay shall try that now
@main olive Nope didn't work ๐ฆ
main olive
what does which pkg-config say?
simple hornet
/usr/local/bin/pkg-config
main olive
hmmm
try doing export PKG_CONFIG=/usr/local/bin/pkg-config and then the pip install again

@main olive I don't know what "snap" is but I'd try doing cd ~ and then trying the command again
my hunch is that your current working directory got deleted
if I'm right, pwd should do something like this: ```py

pwd: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
out of ideas, then ๐ฆ

restive helm
Hey guys! Quick question ๐
I'm using the nohup command to run a couple of my bots 24/7 , is there a way to stop one specific bot that is being ran by nohup?
Like is there a way I can specify a directory where I ran this .py and stop it?
fickle granite
not by directory, no -- but I think nohup tells you the "process ID" when it starts. If you still have that, you can do kill 12345 (where 12345 is the process ID)
restive helm
Yeah indeed, you can also do ps -ef |grep nohup to see all the nohup processes which are running at the moment @fickle granite
which also shows the process ID - but I never know which ID is which .py file
fickle granite
sounds reasonable
if you're brave, you can poke around under /proc; there's lots of detail in there about each running program. You might find the cwd, and the arguments, and whatnot
assuming you're on Linux
main olive
@restive helm easy method (that was used commonly back in the day, but is considered "hacky" today): create pid files
each of your bot will create a pidfile. For example, bot1 creates /var/run/bot1.pid, which just contains the PID of bot1
for example, with sshd:
second method, which is a tad bit harder to set up but more modern and beneficial in the long run: Don't use nohup. Set up systemd units.
I personally recommend the latter
makes everything a bit easier - for example, logging is suddenly very easy, as you can just do journalctl -u bot1 to see what bot1 has printed; starting/stopping bots is easier with systemctl start/stop/restart/etc bot1, you can enable them to run on startup, and so on
