Disk usage in bash

I run several headless systems and sometimes I need to know the disk usage of a particular directory. We have several choices, from the ls command to the ncurses ncdu utility.

For what I need 'ls' does not provide support out of the box. The ncdu looks more alike but I don't need ncurses dependencies or other tools added to my toolbox. I need a 10 line bash script, eventually written by myself 🙂 (let's reinvent the wheel, don't we?)

My solution

Create a bash script called "du1" (or whatever you like). So this is how you get disk usage in bash:

The result

That's why I think Linux can be fun!

Now, if you think that this article was interesting don't forget to rate it. It shows me that you care and thus I will continue write about these things.
