If standard input is a terminal, redirect it from /dev/null.
If standard output is a terminal, append output to nohup.out if possible,
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 shells documentation
for details about the options it supports.
