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.

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 `&''.
