I need a script (written in PERL) that will traverse a directory recursively (all sub directories within that directory) and get a list of any files that have been changed.
Then all of those files should be transfered to a remote server via SCP. A authorization_key will be used to avoid needing a password for SCP.
Essentially this is a CRON job to make sure a bunch of modules are updated on a remote secondary server, whenever the primary server changes. The script will run every 5 minutes so it should be efficient.
