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. 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 ALSO chmod(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. Page 1
