Full Discussion: nohup and & versus functions
Special Forums UNIX and Linux Applications nohup and & versus functions Post 302512769 by Corona688 on Monday 11th of April 2011 03:07:07 PM

nohup can't run functions, period. nohup is not a shell builtin, so only runs executable files.

& should work, though. You can do nohup's signal-trapping + redirection in the shell itself too.

Code:
( trap "true" HUP ; myfunction ) > nohup.out 2>/dev/null </dev/null & disown

disown may not be needed on all shells.

If it doesn't work you'll need to post your complete code, plus what your system and shell is, to figure out what's going wrong.

NAME
nohup - run a command immune to hangups, with output to a non-tty SYNOPSIS
nohup COMMAND [ARG]... nohup OPTION DESCRIPTION
Run COMMAND, ignoring hangup signals. --help display this help and exit --version output version information and exit If standard input is a terminal, redirect it from /dev/null. If standard output is a terminal, append output to 'nohup.out' if possible, '$HOME/nohup.out' otherwise. If standard error is a terminal, redirect it to standard output. To save output to FILE, use 'nohup COMMAND > FILE'. NOTE: your shell may have its own version of nohup, which usually supersedes the version described here. Please refer to your shell's doc- umentation for details about the options it supports.
