NAME
       Dislocate - disconnect and reconnect processes

SYNOPSIS
       dislocate [ program args...  ]

INTRODUCTION
       Dislocate allows processes to be disconnected and reconnected to the
       terminal.  Possible uses:

              •   You can disconnect a process from a terminal at work and
                  reconnect from home, to continue working.

              •   After having your line be dropped due to noise, you can get
                  back to your process without having to restart it from
                  scratch.

              •   If you have a problem that you would like to show someone,
                  you can set up the scenario at your own terminal,
                  disconnect, walk down the hall, and reconnect on another
                  terminal.

              •   If you are in the middle of a great game (or whatever) that
                  does not allow you to save, and someone else kicks you off
                  the terminal, you can disconnect, and reconnect later.

USAGE
       When run with no arguments, Dislocate tells you about your disconnected
       processes and lets you reconnect to one.  Otherwise, Dislocate runs the
       named program along with any arguments.

       By default, ^] is an escape that lets you talk to Dislocate itself.  At
       that point, you can disconnect (by pressing ^D) or suspend Dislocate
       (by pressing ^Z).

       Any Tcl or Expect command is also acceptable at this point.  For
       example, to insert the contents of a the file /etc/motd as if you had
       typed it, say:

            send -i $out [exec cat /etc/motd]


       To send the numbers 1 to 100 in response to the prompt "next #", say:

            for {set i 0} {$i<100} {incr i} {
                expect -i $in "next #"
                send -i $out "$i\r"
            }

       Scripts can also be prepared and sourced in so that you don't have to
       type them on the spot.

       Dislocate is actually just a simple Expect script.  Feel free to make
       it do what you want it to do or just use Expect directly, without going
       through Dislocate.  Dislocate understands a few special arguments.
       These should appear before any program name.  Each should be separated
       by whitespace.  If the arguments themselves takes arguments, these
       should also be separated by whitespace.

       The -escape flag sets the escape to whatever follows.  The default
       escape is ^].

CAVEATS
       This program was written by the author as an exercise to show that
       communicating with disconnected processes is easy.  There are many
       features that could be added, but that is not the intent of this
       program.
