Indeed a quick grep of scripts in /usr/bin shows most reset the path. I was refering to my own ~/bin scripts and shell aliases where I'm too lazy to do it. Perhaps I'm wrong but PATH is intended to avoid typing the full pathes, not to bring the need back.
On a second thought, having '.' in the *end* of the path is almost safe. Not that I'd use it anyway, I'm typing dotslash automatically now :-). -- Beni Cherniavsky <[EMAIL PROTECTED]> The mind of a good coder knows what his computer would do for any of his programs.
