nohup: Linux Commands HowTo
nohup: Run a command immune to hangups
No Hang Up. Run a command immune to hangups, runs the given command with hangup
signals ignored, so that the command can continue running in the background
after you log out.
SYNTAX
nohup Command [Arg]...
`nohup? increases the scheduling priority of COMMAND by 5, this
gives a slightly lower priority.
If standard output is a terminal, it and standard error are redirected so that
they are appended to the file `nohup.out?; if that cannot be written to, they
are appended to the file `$HOME/nohup.out?. If that cannot be written to, the
command is not run.
If `nohup? creates either `nohup.out? or `$HOME/nohup.out?, it creates it with
no "group" or "other" access permissions. It does not change the permissions
if the output file already existed.
`nohup? does not automatically put the command it runs in the background; you
must do that explicitly, by ending the command line with an `&?.
