Ncdu (opens new window) is a disk usage analyzer that you can use to find space hogs in your lab.
Ncdu aims to be fast, simple and easy to use. It uses a ncurses interface, and should be able to run in any minimal POSIX-like environment with ncurses installed.
Although this guide for your lab, Ncdu is a useful tool even on regular desktop systems such as OS X and MacOS and Linux.
Log into your lab and install
ncdu using the following command:
sudo apt install ncdu
# General usage
ncdu in the directory that you want to analyze:
Depending on your volume sizes and number of files, the initial scanning may last from seconds to several minutes.
This is an example of a scan of a
/mnt/work volume where the software (46GB) and workbench (23GB) folders take up most of your space.
# Analyse your root volume
To find what's taking space on your root volume (/), use the
-x paramter. This excludes other volumes mounted on your machine (such as /mnt/work):
ncdu -x /
# Analyze specific volumes
You may use this example to analyze disk usage on specific volumes:
ncdu -x /mnt/archive
