You can set incron to monitor a particular file or directory for changes and schedule jobs for when those changes occur. Fedora users can use yum to install incron with the yum install incron command. Once installed, you need to start the incron daemon before you can schedule jobs. The command, service incrond start, executed as root, will start the incron daemon on and the chkconfig incrond on command will configure it to be started at boot time.
