    Thank You, Aaron! An idea for next article: how to create separate php log file and send it by email as attachment every day.

    Instead of placing the script in /etc, place it in /usr/local/bin or $HOME/bin as a user or /usr/local/sbin if you are root.

  4. HZ says:


    free=$(free -mt | grep Total | awk '{print $4}')

    is a really ugly solution. If you want to filter a text and do something with the filtered values in awk/perl/etc, don’t use grep!

    Try something like this, please:

    free=$(free -mt | awk '/Total/{ print $4 }' )
