Unix Tip #4545- August 21, 2025
FIND THE HOG
Hot Tip for Space Cops: (aren't we all?)
If your users keep using up all the space in your home directory,
here is a way to apprehend the top offenders.
cd /home
du -ks *|sort -nr|pg
(Note: The "k" option may not be necessary in non-posix systems.)
This string will show you all the directory sizes in order,
largest first. Now if you are going to do a little cleanup yourself,
in one of those directories run:
ls -ls|sort -nr|pg
This will list files by size largest first. That way when you do your compress,
move, or remove, you may actually reclaim a significant amount of space.
