script to process something until any key pressed?
2007-12-25 5:07:00
I'm working on a simple ksh script that has to
process something until the user pressed a
key.
Unfortunately I can't figure out how to feed this with
ksh.
Here's what I have so far...
#!/bin/ksh
function check_key
{
if [[ -z "$MESSAGE" && "$MESSAGE" = "q" ]]
then
return 1
else
exit
fi
}
until check_key
do
echo "XXXX"
sleep 2
read MESSAGE
done
The problem is that the script waits for the user
input after the first loop instead of running
indefinitely until someone presses a key.
Is it achiavable at all in a script?
Thanks in advance!
Regards,
John
