Yep, I just tried that too. It catches that. It also catches the in/output of subshells - like, say, kicking off sh interactively. Similarly, if you're running text-based emacs, it catches the output of spawning to a shell from there and doing things. The only restriction I have run into so far, it that - for obvious reasons - sudo cannot see into what you're doing if you kick off an X application like xterm or graphical emacs, for instance. > -- ---------------------------------------------------------------------------- Tim Daneliuk tundra@tundraware.com PGP Key: http://www.tundraware.com/PGP/
