Hi, i've got the following:

SYNOPSIS

DESCRIPTION
Run COMMAND, ignoring hangup signals.

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.
