What OS are you on? Linux has the inotifywait command. It waits (does nothing) and causes the script to sit there until a file changes:

Code:
while true
do
  inotifywait -e modify myfile
  echo 'file myfile changed' | mailx -s 'file change'  me@mycompany.com
  # put command here to run other programs
done
