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.
