Shell Programming and Scripting

Hi Folks,

I am trying to write a simple script which involves a potentially infinite loop repeating a number of tasks quickly.
I would like to enable the user to break out of this when he/she wishes (some key stroke) but not to break out of the script (i.e. which is what happens when a user uses [ctrl c]). This is because i then want a number of additional commands to execute after the loop is broken. Currently i have 2 separate scripts which i call from the command line as:

$>script1 ; script2

I would like to make a neat script which would contain everything needed.
Thanks in advance

Code:

#! /usr/bin/ksh
INTERRUPT=0
trap INTERRUPT=1 INT

while ((!INTERRUPT)) ; do
       sleep 2
       echo "loop 1      INTERRUPT = $INTERRUPT"
done

echo outside loop
exit 0

Hey thanks for that, i tried it and it works. Could i be cheeky and ask how it works though? I tried reading the man page for 'trap' but to be honest its not making an awful lot of sense how your use of it worked.

Thanks again

Oops, i think i have it now, i wasn't looking at the ksh definition of trap in the man page.....however i can't seem to get a list of possible signals to use, although it says that if you call trap with no arguments it should give you a list??? Any ideas.

Thanks

at the command line type kill -l to get a list of signals.
