Today while I was upgrading my ArchLinux I noticed that my root partition was running out of space. Since I didn't want to clear the whole pacman cache I had to quickly find which packages in pacman's cache directory are using the most space in order to delete them. Here is a quick command to list a directory contents, sort them by size in reverse order and display their size in human readable format (e.g. KB, MB, GB etc.).
l: list contentsS: sort by sizeh: human readabler: reverse order while sorting
A quick Linux command tip for the Linux users!
