NOHUP(1)		FreeBSD	General	Commands Manual		      NOHUP(1)

NAME
     nohup -- invoke a utility immune to hangups

SYNOPSIS
     nohup [--]	utility	[arguments]

DESCRIPTION
     The nohup utility invokes utility with its	arguments and at this time
     sets the signal SIGHUP to be ignored.  If the standard output is a	termi-
     nal, 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 iden-
     tical 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 nohup	utility	uses the directory named by HOME to
	   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
     builtin(1), csh(1), signal(3)

STANDARDS
     The nohup utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compat-
     ible.

BUGS
     Two or more instances of nohup can	append to the same file, which makes
     for a confusing output.
