NAME
nohup —
invoke a utility immune to
hangups
SYNOPSIS
nohup |
[--]
utility [arguments] |
DESCRIPTION
Thenohup utility invokes utility
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 variables are utilized by
nohup:
HOME- If the output file nohup.out cannot be created in
the current directory, the
nohuputility uses the directory named byHOMEto create the file. PATH- Used to locate the requested utility if the name
contains no ‘
/’ characters.
EXIT STATUS
The nohup utility exits with one of the
following values:
- 126
- The utility was found, but could not be invoked.
- 127
- The utility could not be found or an error occurred
in
nohup.
Otherwise, the exit status of nohup will
be that of utility.
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.
