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

NAME
     nohup -- invoke a command immune to hangups

SYNOPSIS
     nohup utility [arg	...]

DESCRIPTION
     The nohup command allows the specified utility to be protected from ter-
     mination if the user should become	logged out (for	example, due to	a mo-
     dem line or TCP/IP	connection being dropped).  To do this,	nohup sets the
     SIGHUP signal(3) ("terminal line hangup") to be ignored, then executes
     utility along with	any arguments.

     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 ter-
     minal, it is directed to the same place as	the standard output.  If the
     output file nohup.out cannot be created in	the current directory, nohup
     attempts to create	the file in the	user's home directory.	If the file
     nohup.out cannot be created, either in the	current	directory or the
     user's home directory, nohup will exit without invoking utility, with an
     exit value	as described below.

ENVIRONMENT
     The following variable is used by nohup:

     HOME  User's home directory.

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
     signal(3)

STANDARDS
     The nohup command is expected to be IEEE Std 1003.2 ("POSIX.2") compati-
     ble.
