This manual page documents the GNU version of nohup. nohup runs the given command with hangup signals ignored and the scheduling priority increased by 5, so that the command can continue running in the background after you log out. If the standard output is a tty, it and the 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 `$HOME/nohup.out'. If that cannot be written to, the command is not run.
If nohup creates the file `nohup.out' or `$HOME/nohup.out', it creates it with no access permissions for group or other. It does not change the permissions of those files if they 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 `&'.
