+====== Colour prompt and ls output with Debian ======
 With the CentOS based IRLP software the output from the ls command was colourised. With Debian this is disabled by default, but is quite simple to enable.
-  - Change to your home directory: ''cd''
+Borrowed from http://jbsteiner.com/article/enabling-colorful-bash-debian-squeeze
-  - Edit ''.bashrc'' with your favourite editor.
-  - Goto line 39 and uncomment ''force_color_prompt=yes''
-  - Save and quit the editor.
-  - Execute the following command to enable the change: ''. .bachrc''
-This will enable coloured ls output for the user you are logged in as, but no one else. There is probably a way to enable this globally if desired.
+  - As root backup ''/etc/bash.bashrc'': E.g. ''cp /etc/bash.bashrc /etc/backup.bash.bashrc''
+  - As root edit ''/etc/bash.bashrc'' to resemble the following, this is a complete copy of the file with the changes, it is safe to replace the file with this:
+<code>
+# System-wide .bashrc file for interactive bash(1) shells.
+# To enable the settings / commands in this file for login shells as well,
+# this file has to be sourced in /etc/profile.
