.SH INTRODUCTION
|

|
|
process without having to restart it from scratch.

If you have a problem that you would like to show someone, you can set
|
| 25 |
|
|
up the scenario at your own terminal, disconnect, walk down the hall,
|
| 26 |
|
|
and reconnect on another terminal.
|

|
If you are in the middle of a great game (or whatever) that does not allow
|
| 30 |
|
|
you to save, and someone else kicks you off the terminal, you can disconnect,
|
| 31 |
|
|
and reconnect later.
|
| 32 |
|
|
.SH USAGE
|
| 33 |
|
|
When run with no arguments,
|
| 34 |
|
|
.B Dislocate
|
| 35 |
|
|
tells you about your disconnected processes and lets you reconnect to one.
|
| 36 |
|
|
Otherwise,
|
| 37 |
|
|
.B Dislocate
|
| 38 |
|
|
runs the named program along with any arguments.
|
| 39 |
|
|
|
| 40 |
|
|
By default, ^] is an escape that lets you talk to
|
| 41 |
|
|
.B Dislocate
|
| 42 |
|
|
itself. At that point, you can disconnect (by pressing ^D) or
|
| 43 |
|
|
suspend
|
| 44 |
|
|
.B Dislocate
|
| 45 |
|
|
(by pressing ^Z).
|
| 46 |
|
|
|
| 47 |
|
|
Any Tcl or Expect command is also acceptable at this point.
|
| 48 |
|
|
For example,
|
| 49 |
|
|
to insert the contents of a the file /etc/motd as if you had typed it, say:
|
| 50 |
|
|
.nf
|
| 51 |
|
|
|
| 52 |
|
|
send -i $out [exec cat /etc/motd]
|
| 53 |
|
|
|
| 54 |
|
|
.fi
|
| 55 |
|
|
|
| 56 |
|
|
To send the numbers 1 to 100 in response to the prompt "next #", say:
|
| 57 |
|
|
.nf
|
| 58 |
|
|
|
| 59 |
|
|
for {set i 0} {$i<100} {incr i} {
|
| 60 |
|
|
expect -i $in "next #"
|
| 61 |
|
|
send -i $out "$i\r"
|
| 62 |
|
|
}
|
| 63 |
|
|
.fi
|
| 64 |
|
|
|
| 65 |
|
|
Scripts can also be prepared and sourced in so that you don't have to
|
| 66 |
|
|
type them on the spot.
|
| 67 |
|
|
|
| 68 |
|
|
.B Dislocate
|
| 69 |
|
|
is actually just a simple
|
| 70 |
|
|
.B Expect
|
| 71 |
|
|
script. Feel free to make it do what you want it to do or just
|
| 72 |
|
|
use
|
| 73 |
|
|
.B Expect
|
| 74 |
|
|
directly, without going through
|
| 75 |
|
|
.BR Dislocate .
|
| 76 |
|
|
.B Dislocate
|
| 77 |
|
|
understands a few special arguments. These should appear before any program
|
| 78 |
|
|
name. Each should be separated by whitespace. If the arguments themselves
|
| 79 |
|
|
takes arguments, these should also be separated by whitespace.
|
| 80 |
|
|
.PP
|
| 81 |
|
|
The
|
| 82 |
|
|
.B \-escape
|
| 83 |
|
|
flag sets the escape to whatever follows. The default escape is ^].

.SH CAVEATS
|
| 86 |
|
|
This program was written by the author as an exercise to show that
|
| 87 |
|
|
communicating with disconnected processes is easy. There are
|
| 88 |
|
|
many features that could be added, but that is not the intent of this
|
| 89 |
|
|
program.
