in thread Capturing bash output without displaying STOUT in terminal
Some programs (e.g ssh when asking for a password) write directly to the terminal, not STDOUT.
$ ssh ikegami@209.197.123.153 2>&1 >/dev/null ikegami@209.197.123.153's password:
You have to create pseudo-tty's (as Expect does) in that case.
IPC::Run supports capturing STDOUT and STDERR separately, and easily. It even supports pseudo-tty creation if you need them.
