This font is used for file and directory names.

This font is used for commands.

This font is used for input the user is expected to enter.

This font is used for “replaceable” text or variables. Replaceable text is text that describes something you're supposed to type, like a filename, in which the word “filename” is a placeholder for the actual filename.

The following fonts are used to denote various programming constructs: class names (CCA “components”), interface names (CCA “ports”), and method names. Also variable names and environment variables are marked up with special fonts.

Sometime we must break lines in computer output or program listings to fit the line widths available. In these cases, the break will be marked by a “\” character. In real computer output, you see a long continuous line rather than a broken one. For program listings, unless otherwise indicated, you can join up the broken lines. In shell commands, you can use the “\” and break the input over multiple lines.
