Alternative command for coloured viewing the size of all files and folders

This is not coloured, but also really nicely ordered by size and visualized:

ncdu - NCurses Disk Usage

apt-get install ncdu

ncdu [options] dir

ncdu (NCurses Disk Usage) is a curses-based version of the well-known 'du', and provides a fast way to see what directories are using your disk space.

Output looks like this:

ncdu 1.10 ~ Use the arrow keys to navigate, press ? for help                       
--- /var/www/freifunk -------------------------------------------------------------
  470,7MiB [##########] /firmware

   35,2MiB [          ] /startseite_site
   11,9MiB [          ] /jungebuehne

ncdu is nice, cause you can install it via apt on debian. Only colors would be cool and an export function that does not use the whole screen.

gt5 - a diff-capable 'du-browser'

gt5 looks quite the same, and there are some colors, but they have no meaning (only all files and folders are green). gt5 is also available via apt:

sudo apt-get install gt5

I see the below information from here.

cdu (for Color du) is a perl script which call du and display a pretty histogram with optional colors which allow to imediatly see the directories which take disk space.

With no arguments, cdu reports the disk space for all subdirectories of the current directory. With only one directory argument, cdu reports the disk space for all subdirectories of the given directory. You can also call du with no predefined options. For more documentation about available options, see the manpage below.
