Symptom

You would like to find big files to clean up a directory

Cause

none

Solution

The command line utility du (disk usage) can be used to get the size of the files and sort can do the rest. Run the following command:

du /home | sort -nr | less

Please note note to use the -h option, this makes the sizes more readable for humans, the M and k will not be sorted correctly. The output of this command is fed into sort to organize the output numerically (-n) and reverses the order (-r). Finally, the output is fed into less, which lets you scroll up and down through the listing and shows you one page at the time.
