To find the 10 largest (filesize-wise) folders in your current working path type:

du -cks * | sort -rn | head -10

or

du -x --block-size=1024K | sort -nr | head -10

and remember if you just want to know how much free space is available don’t forget the classic old df -h command:

root@server [~]# df -h
