Will try... Thanks Rene

Updated to also detect changed .html files.

Hi Rene; I've finally find the time to test your script :-)

I'm absolutly a dummy at this time in bash script. Neverthless, I've adjusted your script with two changes :

1. add support of .htaccess files (just a copy/paste of one of your line)
2. put a "Mail sent by ..." and the fullname of the running script (fg.i. /usr/local/sbin/newfiles).

This second changes to allow, the webmaster who receive the file, to know which script to stop f.i. in order to no more receive the email when changes are detected.

I've added these two lines :

SCRIPT_FULLNAME=$(cd `dirname "${BASH_SOURCE[0]}"` && pwd)/`basename "${BASH_SOURCE[0]}"`
echo "List generated by $SCRIPT_FULLNAME" >> $EMAILMSG

Thanks, once again, for you sharing.
