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
restart 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 "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 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.
