How to find the 10 largest files on disk

duffy -n 10 /

What is it?

This is kind of like running the shell command du ("disk usage") like this, to find the largest files in a directory:

du -ah <directory> | sort -rh | head -n 10

duffy is a wrapper around du which updates the list of biggest files in real time while the command is running.

This is useful when you are trying to hunt down huge files in large directories or on a slow disk, and you care more about doing it quickly than about du exploring absolutely every single file before you can see anything.

By default, it shows as many files as will fit on the screen. You can also specify the number of files that will be shown using -n.

The output looks pretty much the same as the human-readable du output:

$ duffy -n 10

Pull requests welcome! This is a fairly simple script that I hacked together in a day, so there might be some rough edges. Feel free to fork it to change any of the behavior.
