NAME
     daemon — run detached from the controlling terminal

SYNOPSIS
     daemon [-cf] [-p pidfile] command arguments ...

DESCRIPTION
     The daemon utility detaches itself from the controlling terminal and exe‐
     cutes the program specified by its arguments.

     The options are as follows:

     -c	     Change the current working directory to the root (“/”).

     -f	     Redirect standard input, standard output and standard error to
	     /dev/null.

     -p file
	     Write the ID of the created process into the file.	 Note, that
	     the file will be created shortly before the process is actually
	     executed, and will remain after the process exits (although it
	     will be removed if the execution fails).

DIAGNOSTICS
     The daemon utility exits 1 if an error is returned by the daemon(3)
     library routine, 2 if the pid-file is requested, but can not be opened,
     otherwise it will return 0.  If the command cannot be executed, an error
     message is displayed on standard error unless the -f flag is specified.

SEE ALSO
     daemon(3), exec(3), termios(4), tty(4)

HISTORY
     The daemon utility first appeared in FreeBSD 4.7.
