In what follows, we shall use the following typographical conventions:

• To aid with navigation the standard Ubuntu Live CD prompt ubuntu@ubuntu:~$ will be shown¹⁾.
• The output of the computer will be shown in standard typewriter font.
• Characters written in bold typewriter font are commands to be typed into the computer as they stand.
• Characters written in italic typewriter font indicate non-specific file or directory names.
• Words or characters typeset like this <key>Ctrl</key> indicate keys to be pressed.

So, for example ubuntu@ubuntu:~$ ls anydirectory <key>Enter</key> means “at the UNIX prompt ubuntu@ubuntu:~$, type ls followed by the name of some directory, then press the key marked Enter”

Don't forget to press the <key>Enter</key> key: commands are not sent to the computer until this is done.

<note> UNIX is case-sensitve, so LS is not the same as ls.

The same applies to filenames, so myfile.txt, MyFile.txt and MYFILE.TXT are three seperate files. Beware if copying files to a PC, since Windows does not make this distinction. </note>
