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 an unreadable file. 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. AUTHOR
