====== UNIX Tutorial  ======



===== Typographical conventions =====

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

  * The command line will be simulated by a blue box labelled "Shell".
  * To aid with navigation the standard Ubuntu Live CD prompt ''ubuntu@ubuntu:~$'' will be shown((This prompt will change as you move around the file system and when you have your own installation)).
  * The output of the computer, including prompts, 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 inserted within square brackets ''[Ctrl]'' indicate keys to be pressed. 

So, for example, 
<box 50% blue|Shell>''ubuntu@ubuntu:~$'' **''ls''** //''anydirectory''// [Enter]</box> 
means "at the UNIX prompt ''ubuntu@ubuntu:~$'', type ''ls'' followed by the name of some directory, then press the key marked Enter" 

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

<box 75% orange|**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.
