[SOLVED] shell.run("PATH")..

My question:
I know the shell.run("PATH") funcion.
BUT- Can somebody explain to me how it EXACTLY works?!
With EXACTLY i mean thing like:
- from where it acts
- if there is a way to go back one direction/folder, how?

Why this question:
I need a way to open programs located in:

"/.minecraft/ComputerCraft/lua/rom/programs"

Thanks

When you say you need a way to open programs, do you mean run them?

If that's the case:
shell.run("programname") will internally first resolve the absolute path of the program you provided.
It literally performs shell.resolveProgram() on your parameter ).
That means if "programname" is in "/rom/programs", then shell.run() will know that.
Finally it will run resolved Path + "prorgamname" ( in this case "/rom/programs/programname" ).

So the only thing you need to worry about is the program name and run it like this:

shell.run( "calculator" )

But if you want, then you can be more specific and provide a path for it to look for your program:

shell.run( "/my/secret/folder/programOfDoom" )

One last thing, in case you didn't know:
The root of any specific computer is the number-folder that represents its ID within this directory:
/.minecraft/saves/YOURWORLD/computercraft/
The rom-folder for all computers is here:
/.minecraft/ComputerCraft/lua/rom/

Yep! i know this too. But ist there a way to run a program located in:
/.minecraft/ComputerCraft/lua/rom/
with 'shell.tun("PATH")'?

I think that just doing shell.run("/rom/Program") will work. I'll check…

EDIT: yep, it works :unsure:/>/>

You're absolutely right, I totally forgot that one, but crucial, folder. My bad, thanks for calling this to attention. :mellow:/>/>
