Howdy, I have an problem while making my OS - How do I make programs global (if it's possible) without editing mod files (like for example "edit" is global)?

Thanks for help :)/>

IIRC, the shell first checks the CWD to see if the file is there then if so runs it, if it isn't in there then it checks the ROM and if it is in runs it, if not it does nothing.

For a single file to be available on all computers, it needs to be in /rom/ someplace, in the mod's files, on the server.

I believe he meant on the single computer that you can access in any CWD like the scripts in ROM.

Ah. His original post was ambiguous.

OP, look into shell.path (or shell.getPath, I can never remember which it is) and shell.setPath.

The shell path function always confused me. I wish it were just a combined getter and setter, so you could do something like this:


shell.path(shell.path() .. ':/bin')

Yeah, there is no documentation about shell.path() in wiki. Anyone has an example code?

shell.path() returns the path, shell.setPath() sets the current path. To append "/bin" to the current path (like I did before):


shell.setPath(shell.path() .. ':/bin')

The colon is there because each individual path is separated by a colon. If you wanted to add more paths, you could make a nice function for it:


function addPath(path)
  shell.setPath(shell.path()..':'..path)
end

addPath '/bin'
addPath '/usr/home'
addPath '/usr/lib'

Or something like that.
