For each of the commands introduced, examples of the relevant outputs are
presented. In these examples, the first line is the command itself (after the
dollar sign prompt). Comments are indicated by the use of square brackets
[...] and long lines are wrapped where necessary. Line breaks for long
lines are indicated by a backslash (\).

The descriptions have been kept short to allow as many utilities as possible
to be mentioned. Further information for all the commands can be found
in the man pages. Most of the commands also understand the parameter
--help, which produces a brief list of the possible parameters.
