NOHUP(1)NOHUP(1)NAMEnohup - run a command immune to hangups and quits
SYNOPSISnohup command [ arguments ]
DESCRIPTIONnohup 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. If standard output is
redirected by the user, then nohup will redirect standard error to the
same destination as standard output.
EXAMPLE
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).]
SEE ALSOchmod(1), nice(1), sh(1), signal(2)WARNINGS
In the case of the following command
nohup command1; command2
nohup applies only to command1. The command
nohup (command1; command2)
is syntactically incorrect.
