nohup
NOHUP(1) User Commands NOHUP(1)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.
