ghost files

[jasong]

Can anyone explain to me how I could install a program, have it appear to be installed, type ls and see it listed, and yet when I try to run it the OS tells me the file doesn't exist?

Probably because the file isn't in your PATH environment variable.

Change to that sub-directory, then type a ./ before the program name to force Linux to run the program in that folder.

Thus is the program's name was 'abc', you would type:

./abc

Thanks for the suggestion, but that's exactly what I did.

Is the program tagged as an executable i.e. 'chmod 0555 abc'

Jason, what is the application? What is the operating system? Are you trying to run a 32-bit program on a 64-bit Linux? If so, have you installed "ia32-libs"?

If the problem were the "bitness", wouldn't it at least acknowledge that the file was there when I tried to run it. It listed when I type ls, but if I try to execute it, even in the directory with the ./ before it, it claims the file doesn't exist.

I'd suggest typing 'ls -l > aa.txt' then post that text file here.

If your program is a script, it may begin with something like

#!/bin/perl -w

or perhaps

#!/usr/bin/sh

or the like.

If you don't have Perl installed on your machine, or if your sh is actually /bin/sh, the OS is trying to tell you that the interpreter for that script doesn't exist, or doesn't exist where the script claims it to be.

I've reinstalled since I had that problem and it hasn't shown up since then, if it DOES come up again , I'll do what you ask. :)

Interesting, does the beta mprime have something like that? Then you could be right.
