du is the linux command to show disk usage.
To show usage of all files in a [directory], in human-readable (-h) format:
du -h [directory]
To show a summary (-s) of a [directory]:
du -hs [directory]
Drop the -h flag if you want usage in Kilobytes (KB).
Excluding files
Use the --exclude option to exclude files by pattern:
me@pc ~ $ du -hs personal
31G personal
me@pc ~ $ du -hs personal --exclude='personal/media/*'
6.7G personal
me@pc ~ $ du -hs personal --exclude='personal/media/*' --exclude='personal/backups/*'
2.4G personal
Order directories by disk usage
This bash script will order by usage the subdirectories of the directory given:
du -sk * | sort -n | while read size fname; do for unit in k M G T P E Z Y; do if [ $size -lt 1024 ]; then echo -e "${size}${unit}\t${fname}"; break; fi; size=$((size/1024)); done; done
As a bash function:
function duf {
du -sk "$@" | sort -n | while read size fname; do for unit in k M G T P E Z Y; do if [ $size -lt 1024 ]; then echo -e "${size}${unit}\t${fname}"; break; fi; size=$((size/1024)); done; done
