nohup(1) nohup(1)
NAME
nohup - run a command immune to hangups and quits
SYNOPSIS
nohup command [arguments]
DESCRIPTION
nohup executes command with hangups and quits ignored. If
output is not re-directed by the user, both standard output
and standard error are sent to nohup.out. If nohup.out is not
writable in the current directory, output is redirected to
$HOME/nohup.out.
EXAMPLES
It is frequently desirable to apply nohup to pipelines or
lists of commands. This can be done only by placing pipelines
and command lists in a single file, called a shell procedure.
One can then issue:
nohup sh file
and the nohup applies to everything in file. If the shell
procedure file is to be executed often, then the need to type
sh can be eliminated by giving file execute permission. Add
an ampersand and the contents of file are run in the
background with interrupts also ignored [see sh(1)]:
nohup file &
An example of what the contents of file could be is:
sort ofile > nfile
FILES
/usr/lib/locale/locale/LC_MESSAGES/uxue
language-specific message file [See LANG on environ(5).]
