1. Getting very fast and clever at the command line -

Keyboard shortcuts and other command line tricks can be used for entering commands in an easy and fast way. Here are some keyboard shortcuts you can make use of within the terminal:
Ctrl-a Move to the start of the line.
Ctrl-e Move to the end of the line.
Alt-] x Moves the cursor forward to the next occurrence of x.
Alt-Ctrl-] x Moves the cursor backwards to the previous occurrence of x.
Ctrl-u Delete from the cursor to the beginning of the line.
Ctrl-k Delete from the cursor to the end of the line.
Ctrl-w Delete from the cursor to the start of the word.
Ctrl-y Pastes text from the clipboard.
Ctrl-l Clear the screen leaving the current line at the top of the screen.
Ctrl-x Ctrl-u Undo the last changes. Ctrl-_
Alt-r Undo all changes to the line.
Alt-Ctrl-e Expand command line.
Ctrl-r Incremental reverse search of history.
Alt-p Non-incremental reverse search of history.
!! Execute last command in history
!abc Execute last command in history beginning with abc
!n Execute nth command in history
^abc^xyz Replace first occurrence of abc with xyz in last command and execute it

2. Launching Ubuntu Linux Applications with keyboard -

There are two ways to do this:
• Using applications like Launchy or Gnome-Do which make it easier to launch applications by typing a few characters of the application’s name.
• You can summon gconf editor (Alt+F2 then type gconf-editor and hit enter), and navigate to apps > metacity > global_keybindings, double clicking on any of the run_command_N and typing in the keyboard shortcut you want to assign to an application then make a mental note of the number N. Then go to apps > metacity > keybinding_commands and double clicking on command_N (N being the number you used above) and type in the command you want to run. As an example if you want to run Firefox you need to simply type in Firefox.

3. Starting from wherever you left off -

You can have Ubuntu remember the applications that were open when you last logged out. This will permit you to log in and find all those applications running from where you left off. You can attain this by going to System > Preferences > Startup Applications, then go to the options tab and check "Automatically remember running applications when logging out"

4. Creating a Separate Ubuntu Linux Home Partition -

Latest versions of Ubuntu are coming every 6 months. Even though you can upgrade to the latest version through the update manager, at times the upgrade doesn’t function as expected so certain users like to do a fresh clean install. The drawback of this is that you will lose data that was there in the home directory. For overcoming this, you can make a separate Home partition while you are installing Ubuntu, size it according to your needs and then when you decide to install Ubuntu subsequently, simply specify this partition as the Home partition (by choosing /home as the mount point).

5. Updating and Installing Ubuntu Linux Software Minus Internet Connection –

There are several ways of doing this. The easiest way is to use APTonCD. APTonCD permits you to make CDs and DVD’s that contain all the packages you want. You can use it to install software on computers minus an Internet connection.

6. Installing new fonts, Microsoft fonts and improving font rendering –

There are not many choices to opt from in Ubuntu. But you can readily install new fonts including those from Microsoft like Arial, Verdana, impact and a lot more. You can utilize varied sites for searching the kind of font you are looking for.

7. Using PPAs, Installing latest versions of software -

There are several steps that a software has to undergo before it becomes part of Ubuntu or becomes available through the Ubuntu repositories. As all those steps offer additional stability, it generally implies you don’t get the latest versions of all the software as soon as they are released. For getting cutting edge, you can search for Personal Package Archives for your favorite software on Launchpad and adding those to your installation’s software sources.

8. Be the root -

The root account is disabled by default on Ubuntu installations primarily to stop you from doing something you had not intended to do. But if you are careful you can enable root account as follows:

1. Type sudo passwd root and provide a root password.
2. Then head on over to System > Administration > Login Window, go to the Security tab and check "Enable local system administrator login"

You should now be able to login as root from the Login prompt. Alternatively you can use "sudo su" for providing your password and get root prompt.

9. Shortening booting time with profiling -

Ubuntu Linux developers have done a fantastic job with the boot time. Jaunty is quick and Karmic even quicker. But there is a bit more you can do by profiling your boot. Profiling allows Ubuntu to create a list of all the files that are accessed during bootup, it then sorts the files based on how they are stored on your hard disk. This will allow your system to get booted and the files read quicker the next time you boot.

For profiling boot you should follow these steps

* At the grub menu highlight the kernel you boot most often.
* Press e for edit.
* Select the line starting with kernel and press e again. Now add the word profile to the end of this line. Hit Enter and then press b to boot

10. Trying out various Ubuntu Linux Desktop Environments and Desktop Managers –

If you are on the lookout for something different than the default Gnome interface, you can check out other desktop managers you can utilize. In case of a complete Desktop Environment you may want, KDE4 has come a long way and is usable and fun. You can do a "sudo apt-get install kubuntu-desktop" to get KDE.
