Yes, exactly, if that code is operating inside a loop like that, it will read from the file and not from the terminal. </dev/tty will always read from the terminal -- if you have a terminal, that is.

So as Corona688 requests, I also must ask how the trap is being called. If there are redirections affecting stdin, maybe read is operating on /dev/null, in which case, it would just carry on since that's your default case statement and KEYHIT would be null...

Edit: My reply took too long.. Is your loop operating as,

Code:
while ...; do
...
done <file

I wonder what read works on then? Smilie

Maybe try read ... </dev/tty inside your trap
Yes the loop 1 is while ....; do
.....
done < file

So I think you've cracked it.....the redirect is confused about where the read should come from!!

read < /dev/tty fixed it.

Thanks

The traps of loops and redirects when your handling live data streams.......
