Events on Log analyse

dough29 · 11-05-2004, 06:55 PM

Hello ! I'm French so sorry if my English isn't the best.

I would like to have a shell script making events analysing my logs in /var/log/

For example, by running tail -f /var/log/apache/access.log - I would like, for each GET requests, to run a command like /usr/bin/beep to make simple.

Thank you in advance !!

Save the follow shell script as beep.sh, then run:
chmod +x beep.sh

Then run:
tail -f /var/log/apache/access.log | beep.sh GET

The argument to beep.sh is the string you want to match on. So if you wanted to look for HEAD requests instead of GET, run it like this:
tail -f /var/log/apache/access.log | beep.sh HEAD

Or for a particular IP address:
tail -f /var/log/apache/access.log | beep.sh "192.168.0.123"

... You get the idea. Also, your English is quite good

Code:

 #!/bin/sh

while [ 1 ]; do
        read foo;
        echo $foo | grep "$1" > /dev/null 2>&1
        if [ $? -eq 0 ]; then
                /usr/bin/beep
        fi
done
