Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Ctl-D Log out from a shell (similar to exit).
When typing text on the console or in an xterm window, Ctl-D erases the character under the cursor. When there are no characters present, Ctl-D logs out of the session, as expected. In an xterm window, this has the effect of closing the window.
Ctl-G "BEL" (beep). On some old-time teletype terminals, this would actually ring a bell.
Ctl-H "Rubout" (destructive backspace). Erases characters the cursor backs over while backspacing.
Ctl-I Horizontal tab.
Ctl-J Newline (line feed).
Ctl-K Vertical tab.
When typing text on the console or in an xterm window, Ctl-K erases from the character under the cursor to end of line.
Ctl-L Formfeed (clear the terminal screen). This has the same effect as the clear command.
Ctl-M Carriage return.
Ctl-Q Resume (XON).
This resumes stdin in a terminal.
Ctl-S Suspend (XOFF).
This freezes stdin in a terminal. (Use Ctl-Q to restore input.)
Ctl-U Erase a line of input, from the cursor backward to beginning of line. In some settings, Ctl-U erases the entire line of input, regardless of cursor position.
Ctl-V When inputting text, Ctl-V permits inserting control characters.
Ctl-W When typing text on the console or in an xterm window, Ctl-W erases from the character under the cursor backwards to the first instance of whitespace. In some settings, Ctl-W erases backwards to first non-alphanumeric character.
Ctl-Z Pause a foreground job.
The really usefull ones according to my experience, are CTR+U, when you are typing passwords. If you realize before you hit the enter, that you have made a mistake since you cannot see the number of caracters printed, CTRL+U will clear the field, instaed of pressing backspace or delete all the time.
CTRL+Z. Some stupid applications catch the ctrl+C (SIGINT), so in order to kill the application, instead of killing the window(if tou are in GUI) or opening new consoles, press CTRL+Z to get your prompt back and then type
to kill it.
