nohup
Localization
Exit Values
Portability
If the standard output is a terminal, nohup appends the utility’s output to a file
named nohup.out in the working directory. This file is created if it doesn’t already
exist; if it can’t be created in the working directory, it is created in your home
directory.
If the standard error stream is a terminal, nohup redirects the utility’s error output to
the same file as the standard output.
nohup simply runs a program from an executable file. command-line cannot contain
such special shell constructs as compound commands or pipelines; however, you
can use nohup to invoke a version of the shell to run such a command line, as in:
nohup sh –c 'command*'
where command can contain such constructs.
nohup in the tcsh shell
With command, nohup runs command such that it will ignore hangup signals.
Commands may set their own response to hangups, overriding nohup. Without an
argument (allowed only in a shell script), nohup causes the tcsh shell to ignore
hangups for the remainder of the script. See “tcsh — Invoke a C shell” on page
626.
nohup uses the following localization environment variables:
v LANG
v LC_ALL
v LC_CTYPE
v LC_MESSAGES
v NLSPATH
See Appendix F for more information.
126 nohup found the utility program but could not invoke it.
127 An error occurred before nohup invoked the utility, or nohup could not find
the utility program.
Otherwise, the exit status is the exit status of the utility program that is invoked.
