To run a Java file, you need to execute it using the Java Virtual Machine (JVM). Here's how you can run a Java file from the command line:

1. Open a terminal or command prompt.

2. Navigate to the directory where your Java file is located using the cd command. For example, if your file is in the "Documents" folder, you can use cd Documents to navigate to that folder.

3. Once you are in the correct directory, use the following command to run your Java file:

   java -jar filename.jar
   

   Replace filename.jar with the actual name of your JAR file.

If you're still unable to run the JAR file, make sure that you have Java Development Kit (JDK) installed on your system and that it is added to your system's PATH variable.

Note: The "unluac" JAR file might not be intended for direct execution but rather as a library for other Java programs. Make sure you have a clear understanding of how to use it before proceeding further.

I tried this, I get an error saying "Unable to access jarfile"

[vast hedge]

which version of Java do you have installed, and did you add .jar? Try wrapping your path in "

[late talon]

I think its Version 8

I have tryped .jar at the end

What do you mean by wrapping your path in?

[vast hedge]

java -jar C:\Path with spaces\someFile.jar vs java -jar "C:\Path with spaces\someFile.jar"

And I'd upgrade to 21

Download latest Java from https://adoptium.net/, run the installer.

Open a CMD and type java -version and javac -version, if both show your new Java version, you have successfully installed Java! 🎉

In order to prevent issues with old installations you may want to remove them. Type where java and where javac. They should only show the new and no old entries:

If that is not the case, you may want to clean up. Therefore, type "environment variable" into the Windows search and follow the dialog. You will see two entries for a variable called Path, one for your user and one for the system. This variable tells Windows where to look for commands, like java and javac.

Edit both. Make sure that they only list the entry to your new Java installation and remove all the old entries you have seen with the where command before:

Confirm and close all dialogs. Restart your CMD window and try where java and where javac again. It should only list the new installation now and nothing else.

Congratulation, your Java is now finally ready, happy coding 🎉

show the command you used to run it

[late talon]

I have used it wrong but I am a still a little confused on how to use it

Here is an example usage of unluac:
java -jar unluac.jar myfile.lua > myfile_decompiled.lua

[crystal remnant]

where did you get the jar from? theres probably instructions

[vast hedge]

you're executing a jar file, passing in your file as input, and outputting it to the decompiled file

[late talon]

https://sourceforge.net/projects/unluac/

[crystal remnant]

so you're probably not specifying the jar location properly

where is the jar?

[late talon]

Okay i see

[vast hedge]

in your terminal, are you in the folder where the files are?

that's why I used the absolute path

[late talon]

the jar file that is "unlac" is in C:\DUMP

[crystal remnant]

so you'd need to use that when specifying the jar

[late talon]

I see

Can you give me an example? Im not sure which order i should type it in

[crystal remnant]

when you specify the file name

so instead of unlac.jar, you would put C:\DUMP\unlac.jar

[vast hedge]

well there are 2 options

[late talon]

I see

[crystal remnant]

could also cd to the directory the file is in

[vast hedge]

you can use the fully qualified path like java -jar "C:\Path with spaces\someFile.jar" or you can use CD so you're in the DUMP folder and then you can do the normal version

[late talon]

Am i doing something wrong here?

[rotund thunder]

https://i.imgur.com/locy9jp.png

does that exist ?

[late talon]

yes

[rotund thunder]

either the file is in use by another process or its a bust jar

also just for the sake of checking things, in your topic your name is different then on the command

https://i.imgur.com/AeRpeRr.png

u got unlac

@late talon

[late talon]

sorry

the file is called unlac yes

[vast hedge]

can you do ls -lrt

[vast hedge]

ah I guess no WSL, my bad. Can you do dir

[vast hedge]

is that the folder you're running it from? I don't see the jar file

[vast hedge]

yes but where you ran the dir command didn't

so in DUMP also place the other two files

[late talon]

which files

[vast hedge]

the lua file

then in your console cd to the dump folder

[brittle sail]

Or just type "cmd" in the folder bar

[late talon]

Okay i see

[crystal remnant]

you could also just specify the path of the files, if you dont want to move them

[brittle sail]

Well you don't know how that jar reads files, it could search inside the installation folder

[brittle sail]

U misspelled the file name

It's unluac

[late talon]

ah

[crystal remnant]

and it could also not, could look in a completely different folder dedicated to lua files. the site doesn't specify

[brittle sail]

That is a custom exception, for this u have to write the devs of that jar or either search for a solution online

[crystal remnant]

its saying the file you passed in isn't a lua file, based on the file signature

[brittle sail]

Probably it's because it doesn't recognize .lua as a lua file

Nah probably because of it's content

[late talon]

bruh

itss alright

Im just trying to decode a lua file

and someone told me that the lua decoder thing would work

[brittle sail]

Maybe that file has been compiled by a newer version of lua the ones supported by the jar

[crystal remnant]

it's a decompiler. you probably need a luac file, not a lua file

[brittle sail]

That too

[late talon]

ah its okay

thank you guys for trying to help

do you guys know if theres anyway to actually be able to read this file or is there no way

[vast hedge]

are you certain you have the right version?

cfr https://stackoverflow.com/questions/64943979/how-to-decompile-a-lua-file

[brittle sail]

Did you try to open the jar file or it is the lua?

[late talon]

its the lua

[late talon]

the right version of?

[vast hedge]

the tool, there are different lua versions. it's what's mentioned in the main answer

[late talon]

I have no idea

somebody just told me to use that tool

[vast hedge]

check out https://stackoverflow.com/a/64944113

https://github.com/viruscamp/luadec

[late talon]

Sure

How do i run it?

how do i know which version lua it is?

[vast hedge]

hex decoder

or easier: https://luadec.metaworm.site/

[late talon]

okay that works
