Ok, weirdly chatGPT answered this correctly, all you need to do is add variable on start of the program that looks like this: local args = {...} and for each argument you wanna look at you just type "args[i]" where i is the number of the argument

I am trying to pass an argument into program to make robot different things base on the argument Lets say I have some program and I type ~ main "Ender Pearl" ~ in which main is my program and I want to pass Ender Pearl as a string into the variables inside, how do I do it, because I cant find anything about it on the internet, and tutorials I watched are so simplified that they are not telling anything about this

as far as i know, file extentions just straight up don't matter. Even if you have none, you can still run the file as a lua file. Running "hello" will check for a file named  "hello", and if it isn't there, it then checks for one called "hello.lua". I think you can change this in /lib/shell.lua (or /lib/core/full_shell.lua, can't remember exactly), it would be in the shell.execute function   Also, sorry for replying 7 years late

.shrc just runs whatever commands when sh.lua is started (in most cases, at boot) (shell run command) File color, when you do ls, is defined in /bin/ls.lua (which is what is ran when you do ls)
