This didn't seem to work, so I took the opportunity to investigate. You also need to trap SIGHUP: # (trap 1; command </dev/null >cmd.stdout 2>cmd.stderr ) & I also noticed along the way that Debian (unlike BSD and V7 which use C binaries; I don't know about other Linux distros) implements nohup as a sh script that does the above with a little more finesse. > Some commands can run in daemon mode where they detach themselves from the > current tty automatically. Looking in a manpage for the option to enable such behavior could be worthwhile. In the more-than-you-wanted-to-know department, understanding how daemons and zombies work is a more advanced topic worth learning about to help interpret the output of ps.
