Typographical Conventions

Typographical conventions

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

• 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 [ ] indicate keys to be pressed.

So, for example,

% ls anydirectory [Return]

means "at the UNIX prompt %, type ls followed by the name of some directory, then press the key marked return"

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