Disk usage using awk

This command will give you the top 20 files or directories that take the most space in the current directory :

sudo du -k -x --max-depth=1 | sed 's/\.$/Total\n/g' | sort -rn | head -20 | awk 'BEGIN{printf "\n%20s %-30s","Size in Kbytes","file or directory"}{printf "\n%20'\''d %-30s", $1, $2} END{print "\n"}'

Here it is in action :)

> sudo du -k -x --max-depth=1 | sed 's/\.$/Total\n/g' | sort -rn | head -20 | awk 'BEGIN{printf "\n%20s %-30s","Size in Kbytes","file or directory"}{printf "\n%20'\''d %-30s", $1, $2} END{print "\n"}'
