NOHUP(1)                     BSD Reference Manual                     NOHUP(1)

NAME
     nohup - invoke a command immune to hangups

SYNOPSIS
     nohup command [arg ...]

DESCRIPTION
     The nohup utility invokes command with its arguments and at this time
     sets the signal SIGHUP to be ignored. The signal SIGQUIT may also be set
     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.

     Nohup exits 1 if an error occurs, otherwise the exit status is that of
     command.

ENVIRONMENT
     The following variable is utilized by nohup.

     HOME  If the output file nohup.out cannot be created in the current di-
           rectory, the nohup utility uses the directory named by HOME to cre-
           ate the file.

SEE ALSO
     signal(3)

STANDARDS
     The nohup command is expected to be IEEE Std1003.2 (``POSIX'') compati-
     ble.
