15 Great Ubuntu Tips For Linux Power Users

A few days back I wrote about books that beginners can download and read to teach themselves Linux. Today in the Linux section we have something for the power users. Here are a few tips you should try out if you are an avid Ubuntu Linux user:

1. Get lightning fast and clever at the command line

You can use keyboard shortcuts and other command line tricks to make entering commands easier and faster. You might already know about the ‘tab’ key which completes partial commands and even file and directory names.

Here are some other keyboard shortcuts you can use within 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. Launch Ubuntu Linux Applications with keyboard

There are two ways you can achieve this:

* Use applications like Launchy or Gnome-Do that make it easier to launch applications by typing a few characters of the application’s name.

* Or you can summon gconf editor (Alt+F2 then type gconf-editor and hit enter), and navigate to apps > metacity > global_keybindings, double click on any of the run_command_N and type 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 click on command_N (N being the number you used above) and type in the command you want to run. As an example if you wanted to run Firefox you would type in firefox.
