Re: sending key strokes with screen

[Michael Grant]

Someone on this list, I cannot remember who, recommended using a
register and then processing the register.  Here is a command I wrote
which redisplays a screen and it's save buffer so when you log back in
and reattach, you can get then scroll up:

register A "\001:hardcopy -h /tmp/mgrant.screendump\015\001:exec
/home/mgrant/bin/redraw-screen\015"

# bind ^A l  (ell) to redraw the screen
bind l process A

and the redraw-screen script:

#!/usr/local/bin/perl
undef $/;

# expects screen dump to already be in /tmp/mgrant.screendump
# from the :screendump -h command in screen
open(FP,"</tmp/mgrant.screendump");

# read screen dump into $a
$a=substr(<FP>,0,-1);

# special case, if the prompt is the last thing in the dump
# append a space
if ($a =~ /\d+]$/s) {
   $a.=" ";
}

# redraw the screen
print $a;

# delete the screen dump file
unlink "/tmp/mgrant.screendump";
