You wish to know which files/folders on your linux server are using up most space?

Sometimes when operating a server you recieve a warning that your disk space is almost used up. (Of course you need a monitoring system for this)
As usual, you don't know what your users are storing where and how much.

To identify the largest folders or files you can use this small command line:

du -a /var | sort -n -r | head -n 20

This shows you the 20 top files/folders under /var.

Of course you can also run it agains your root folder, it will then take somewhat longer to complete.
For more details look at this post.
