    Can this SCript Send a mail with output?
    Can someone tell me how i can send a mail with above ip list.

    The sort on ip’s is alphabetic which is not quite right for looking at the numbered segments. so your script only works because the second sort is working on the count produced by uniq -c. Is the first sort even needed?

    I think you should pipe the output of the report generating command to tail, otherwise you will get “every” address logged to your resulting report file. And the title of the script is top ip addresses accessing apache / lighthttpd not all unique ip addresses which is what your script is producing.

    Here a what i mean, with this you get the top 20 hitters only.
    awk ‘{ print $1}’ $LOGFILE | sort | uniq -c | sort -nr | tail -20 > $DEST/$DOM.txt

      Use “head” instead of tail, this way output shows only last 20 IP hit your website just one time.

      Top 20 IPs hits site multiple times.
      awk ‘{ print $1}’ $LOGFILE | sort | uniq -c | sort -nr | head -20 > $DEST/$DOM.txt

    Set LOGFILE variable. Usually, each server is configured with different location.

    Great script !! I made a script somewhat like this to check secure logs for failed ssh connections.
    Keep up the good work!
