Sometimes it is useful to find the folders that occupy the most space in your disk. A simple command is the following:
sudo du -h /var | sort -nr| grep [0-9]M | head -20
This command provides in human readable form (-h) the top 20 directories in the /var
This is the beginning of my site. Hope you find the material interesting since I am going to post code and comments on software and development issues.
