du

Overview

Notes on using the linux du utility.

Get the size of the current directory with label for the total

du -ch | grep total
2.5G        total

Get the size of the current directory only

du -s

Example

du -s
30248   .

Make file size human friendly

du -sh

Example

du -sh
30M .

List all directories in the current directory (non-recursive)

du -sh *

Example

du -sh *
16K config.yaml
200K    files
30M puppet
116K    shell

By default du listings are recursive and redundant
