NAME

nohup − run a command immune to hangups (sh only)

SYNOPSIS

nohup command [ arguments ]

DESCRIPTION

Nohup executes command immune to terminate (EOT, control-D) signal from the controlling terminal.  With nohup, the priority is automatically incremented by 5. Nohup should be used with processes running in background (with "&") in order to prevent it from responding to interrupts or stealing the input from the next person who logs in on the same terminal.  In csh, processes run in background are automatically immune to hangups.

If output is not redirected by the user, it will be sent to nohup.out.  If nohup.out is not writable in the current directory, output is redirected to $HOME/nohup.out. 

EXAMPLE

nohup  nroff -ms  docsfile | lpr

runs the nroff command shown, immune to hangups, quits, and interrupts. 

FILES

nohup.outstandard output and standard error file.
