du Command Output In Human Readable Format ( GB / MB / TB )

Posted on in Categories last updated July 15, 2011

I need to get a list of sizes in human readable du output format. How do I get the output for du command in GB under Linux or UNIX operating systems?

The du command is used to estimate file space usage. To print sizes in human readable format such as 5K, 400M, or 3G, type the following command:

du -h
du -h /tmp
du -h /home/vivek

Sample outputs:

25M	./scripts
317M	./softwares/vmware-workstation-7
4.2G	./softwares/rhel-6-workstation
4.5G	./softwares
6.5M	./pdfs/SecurityGuide
1.3M	./images-up
2.6M	./images-down
1.4G	./iso-images/OracleSolaris11Express2010_11_VM
4.9G	./iso-images

You can sort du command output using the sort command:

du -hs * | sort -h

All commands were tested using GNU/Linux and GNU coreutils v8.x only. Please refer to your local Linux / UNIX du and sort command man pages for more information.
