GNOME Shell is a whole new take on the concept of the desktop and Compiz, one of the most amazing Windows managers (at least in terms of eye candy), had no place in GNOME Shell. KDE SC too already have their own windows manager, KWin, to provide most of the bling that Compiz provided. It seemed that Compiz was doomed to become “a project without a cause”.

Well, Mark Shuttleworth made an announcement which ensures that Compiz will live on. In the Ubuntu Developer Summit – Natty, while announcing that Ubuntu 11.04 Desktop will come with the Unity interface, he also announced that Unity in Ubuntu 11.04 will use Compiz.

Currently, Unity is available in Ubuntu Netbook Edition 10.10. It is based on Mutter, the same technology which GNOME Shell uses. Unity in UNE 10.10 is heavily criticized for a lot of things –  from being too confusing to being slow. According to Canonical, Unity’s slowness is because of Mutter and Mutter is not capable of providing a good enough performance. So, for the next release they will replace mutter with Compiz.

It is good to know that Compiz finally has a proper backing. Although, I have never been a fan of Compiz, it is one of those things which attracts a lot of people to Linux.

If you used cd to change the directory in Linux you can easily go back to the previous directory by using a command. For example you were in /usr/keith/my/inner/directory/which/is/so/deep and you use the command cd /var/www you can go back to the previous directory without having to type in the entire directory path by using the command cd .

If you want to go back to your default home directory from any directory, type in either cd ~or simply cd, this should take you to your home directory.

Bonus Tips: If you want to find the exact directory you are in type the command pwd”. If you want to navigate to a sub-folder in your home directory you can use the ~ sign to replace the path to your home directory, so cd /home/keith/dir1 and cd ~/dir1 should take you to the same directory.

You can also use auto-completion for file and directory names by using the tab key, if there are more than one files or folders matching the text you typed in, you will be shown a list of entries to choose from.
