i have clubed bunch of commands to zip the log files and move to a directory name with date stamp and remove the files older than 6 months....

right now i have saved this file in .sh and scheduld this to run every 30 days... it goes like this.
-------------------------------------------------------------------

NOWDATE=`date +%d%m%y`
mkdir -p /var/log/httpd/folders_log_$NOWDATE/access_log_$NOWDATE
mv /var/log/httpd/access_log.* /var/log/httpd/folders_log_$NOWDATE/access_log_$NOWDATE
mkdir /var/log/httpd/folders_log_$NOWDATE/access-ssl_log_$NOWDATE
