GONE(1)                DragonFly General Commands Manual               GONE(1)


NAME

     gone - a terminal locking utility with many improvements over lock


SYNOPSIS

     gone [-bvpxl] [-y | -n] [-t timeout]


DESCRIPTION

     gone is a utility that locks a terminal with a password chosen by the
     user.  gone will prompt the user for a password, then print the gone
     banner, then drop into the gone shell.  From this shell, only a
     restricted set of commands can be run.  gone will also disallow messages
     by removing permissions on the parent tty.  After the timeout period (10
     minutes by default), gone will automatically log the user out.

     If gone is installed setuid to root, then specifying the -p option will
     instruct gone to read the password from the system password file/database
     instead of prompting the user.  Setuid'ing the program is done by setting
     the environmental variable with_setuid to ``yes'' then running configure.

     Options:

     -b          Supress printing the gone banner.

     -v          Print the version number and exit.

     -p          Read the password from the system password database (must be
                 setuid root at install-time).

     -x          Supress processing of extended shell commands (see the
                 section on shell commands below).

     -l          Prevent VTY switching if supported by the platform.

     -y          By default gone turns messages off (see mesg(1) ).  This
                 option will turn messages on.

     -n          Same as the -y option (deprecated).

     -t timeout  Specify an optional timeout value in minutes.  Default is 10
                 minutes.  If set to 0, gone will lock the terminal
                 indefinitely.

     gone also accepts an optional string that is visible by using the w(1)
     command.  Use this, and other users can see why you are gone.


SHELL COMMANDS

     Commands for the gone shell (these commands can be abbreviated):

     w       Invoke a UNIX w(1) command (extended command).

MINUTIAE
