UNIX Tutorial 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 [Ctrl] indicate keys
to be pressed.
So, for example,
% ls anydirectory [Enter]
means "at the UNIX prompt %, 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.
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 DOS and Windows
do not make this distinction.
