nohup(1)
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).)

Notices
In the case of the following command
nohup command1; command2
nohup
applies only to
command1.
The command
nohup (command1; command2)
is syntactically incorrect.
