ncdu

ncdu is a well-known command for examining which files and directories are taking up the most space on your system.

Usage

Navigate to the directory you're interested in, and type

ncdu

Be patient as it needs to scan all of the files and directories recursively from your current working directory. Eventually, it will open up a pretty list of these files sorted so that the largest file/directory is at the top (see screenshot below). To navigate these files, use the arrow keys. Press Enter to go inside a directory. Press ? for more help.

You can also specify a path when using ncdu if you want to analyse somewhere other than your current working directory.

ncdu /projects/nq46
