—
invoke a command immune to

SYNOPSIS
nohup |
[- - ]
command [arguments] |
DESCRIPTION
Thenohup
utility invokes command
with its arguments and at this time sets the signal
SIGHUP
to be ignored. If the standard output is a
terminal, the standard output is appended to the file
nohup.out in the current directory. If standard error
is a terminal, it is directed to the same place as the standard output.
Some shells may provide a builtin nohup
command which is similar or identical to this utility. Consult the
builtin(1) manual page.
ENVIRONMENT
The following variable is utilized by
nohup
:
HOME
- If the output file nohup.out cannot be created in
the current directory, the
nohup
utility uses the directory named byHOME
to create the file.
EXIT STATUS
The nohup
utility exits with one of the
following values:
- 126
- The command was found, but could not be invoked.
- 127
- The command could not be found or an error occurred
in
nohup
.
Otherwise, the exit status of nohup
will
be that of command.
SEE ALSO
STANDARDS
The nohup
utility is expected to be
IEEE Std 1003.2 (“POSIX.2”)
compatible.
BUGS
Two or more instances of nohup
can append
to the same file, which makes for a confusing output.
