 ====== ncdu - NCurses Disk Usage ======
+<color #db5f0b>Jun 2017</color>
+\\
+\\
+----
+ncdu is an excellent way to look at disk space usage on a linux based system. Ncdu is a disk usage analyzer with an ncurses interface. It is designed to find space hogs on a remote server where you don't have an entire graphical setup available, but it is a useful tool even on regular desktop systems. Ncdu aims to be fast, simple and easy to use, and should be able to run in any minimal POSIX-like environment with ncurses installed.

+\\
+===== Installation =====
+\\
+From the command line (you will need to have epel-releases installed, or you won't find the repositories).
+\\
+    yum install ncdu
+\\
+\\
+Once installed you can launch the application from the command line using:
+\\
+    ncdu
+\\
+\\
+----
+===== Useage =====
+\\
+Below is an example of ncdu running on a packager v8.

+By using a combination of Enter and the arrow (cursor) keys you can navigate in and out of directories, in the example below I have navigated in to the <color #ed1c24>/mnt/nas/sda3store</color> directory, and I can see how much disk space the two services being packaged are consuming.

+Annoyingly, this program doesn't seem to give you information on total disk sizes, so you can't work out how much space is left.
