Background
For a long time, I've been looking for somewhere to post a small number of bash scripts I've borrowed/hacked from various places online, and Steemit seems to be the most natural place to create a repository of short, but useful scripts that I use on a daily basis.
Today's Script
This script lists the top 20 directories from your current directory downwards, in terms of size.
Why might this be important?
Simple answer: if you manage/own a hard drive or web server (I manage a few VPS servers), then you want a quick way to see which directories have become bloated, and delete unwanted files accordingly.
Webservers can particularly get full, quickly, if there are various backup scripts running.
Here's the Script:
du -h . | sort -nr| grep [0-9]M | head -20
Normally, I'll put this into a file in /usr/local/bin, as follows:
sudo echo "du -h . | sort -nr| grep [0-9]M | head -20" > /usr/local/bin/whatsup
sudo chmod +x $!The above commands enable me to use this command:
whatsup...to list those top 20 offending bloated directories.
So there you go: a simple script to quickly enable me to track down bloated directories, so I can then dive in, and remove backup files that haven't yet been deleted automatically.
Hope that helps!
