Here is the change channel script I am using (it was created by MythDora):

#!/bin/bash
#STB channel changer created by mdconfig
PATH=/bin:/usr/bin:/usr/sbin
REMOTE=Hauppauge_350
for digit in $(echo $1 | sed -e 's/./& /g'); do
     irsend --device=/var/run/lirc/lircd SEND_ONCE $REMOTE $digit
     sleep 0.2
done
irsend --device=/var/run/lirc/lircd SEND_ONCE $REMOTE OK

I don't see a procedure to return an exit code. I also checked several 
other scripts online and don't see that they return an exit code either.

Besides which, I fail to see TV even with an empty file for the script. 
How can an empty file error out?
