Example: Running multiple background processes in one bash script, killing all on SIGINT (ctrl+c)

compile.sh

#!/bin/bash
SITE=/home/dev/sites/rmx

# Arbitrary shell commands, some run in background
echo "RMX using siteroot=$SITE"
$SITE/rmx/manage.py runserver &
compass watch $SITE/media/compass/ &
coffee -o $SITE/media/js -cw $SITE/media/coffee &
hamlpy-watcher $SITE/templates/hamlpy $SITE/templates/templates &

# The magic line
#   $$ holds the PID for this script
#   Negation means kill by process group id instead of PID
trap "kill -TERM -$$" SIGINT
wait

Thanks!

Nice, thank you!
