hi,
i'm trying to keep process running after script kills xterm like this:
#!/bin/bash
firefox & disown -h $!
kill -9 $PPID
but when xterm terminates, firefox terminates too.
`disown -h' only keeps bash from sending SIGHUP to its child processes.
It doesn't change child processes' signal handling, and it doesn't keep
other processes -- like xterm -- from sending SIGHUP, or any other signal,
to them.
