How to regain the focus back to the launch window?
Consider this code snippet below:-
Code:
char=`which afplay`
if [ "$char" != "" ]
then
xterm -e 'while true; do clear; echo "Press Ctrl-C to Quit..."; afplay /tmp/pulse.wav; done' & > /dev/null 2>&1
fi
This launches a second terminal window that generates a specific waveform for the next calibration of AudioScope.sh.
It works perfectly except for one minor problem.
When Ctrl-C in pressed in this new terminal window it closes down but does NOT return the focus back to the launch, (AudioScope), terminal window.
I have to click inside the window to return the focus back to the AudioScope window.
AudioScope.sh still runs fine when not in focus but when COMMAND mode appears I have to refocus the window before entering text.
Is there any method to refocus it, or is it 'Tough! You will just have to put up with it'?
Using no xterm at all and launching using eval requires that I kill the process when finished with. The only thing is whether this is a frowend upon method because of 'eval'.
This actually works a real treat and places me straight back into my shell ready for the kill command...
Code:

AMIGA:barrywalker~> eval 'while true; do afplay /tmp/pulse1.wav; done' &
[1] 19272
AMIGA:barrywalker~> kill 19272
[1]+ Terminated: 15 eval 'while true; do afplay /tmp/pulse1.wav; done'
AMIGA:barrywalker~> _
Thanks for pointing me to a lateral solution...

Why do you use the eval construct? What difference does it make without eval?
And, depending on how many background jobs you have, kill %1 (in above case) might be easier to type.
Is it possible to toggle back and forth between an xterm invoked from one tty, and a shell invoked from a different tty?
