A lot of this depends on your OS and your terminal software. The syntax you would use can vary depending on which *nix you're running so 'man ps' and RTFM. The terminal emulator you use should have line wrapping turned on (if it's an option). Other options may help as well - RTFM again and YMMV.

The reason I'm not actually answering your question is that 'ps -ef' on my Debian system accessed via putty from my WinXP system emulating an xterm with Autowrap turned on displays long paths/command lines (167 characters) just fine. I do recommend piping the 'ps -ef' through an appropriate grep (eg 'ps -ef | grep <username>').

Hope this helps, Jack
