NAME
     Dislocate - disconnect and reconnect processes

SYNOPSIS
     dislocate [ program args... ]

INTRODUCTION
     Dislocate allows processes to  be  disconnected  and  recon-
     nected to the terminal.  Possible uses:

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

          o   After having your line be dropped due to noise, you
              can get back to your process without having to res-
              tart it from scratch.

          o   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.

          o   If you are in the middle of a great game (or  what-
              ever)  that does not allow you to save, and someone
              else kicks you off the terminal,  you  can  discon-
              nect, and reconnect later.

USAGE
     When run with no arguments, Dislocate tells you  about  your
     disconnected  processes and lets you reconnect to one.  Oth-
     erwise, 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 "n"xt #"
          }   send -i $out "$i


     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 under-
     stands  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.
