Disk usage analyzer
You can start nnn in its du mode with the command nnn -S.
It’s a really useful mode helping me to recover a significant chunk of hard disk space without needing to fire up a separate utility.
The software doesn’t do a complete scan of your hard disk, but there’s very little wait time traversing around the directory structure. including moving from my home directory to /.
The status bar shows useful information including the number of files in the directory, the selection mode, the disk usage of the directory (and any sub-directories), the amount of free space on the hard disk space, and more.
If you start nnn without the -S toggle, you still have access to the disk usage functionality. Press the t key in nnn, and the status bar changes to show:
We can then access the disk usage functionality by pressing d, whereas pressing a shows the apparent disk usage. There’s also sorting options here too.
