The default behavior for a command may usually be modified by adding a <emphasis role="strong">-- <emphasis>option</emphasis></emphasis> to the command. The <link linkend="ls"><command>ls</command></link> command, for example, has a <emphasis role="strong">-s</emphasis> option so that <command>ls -s</command> will include file sizes in the listing. There is also a <emphasis role="strong">-h</emphasis> option to get those sizes in a "human readable" format.

Options can be grouped in clusters so <screen>ls -sh</screen> is exactly the same command as <screen>ls -s -h</screen> Most options have a long version, prefixed with two dashes instead of one, so even <screen>ls --size --human-readable</screen> is the same command.

Virtually all commands understand the <emphasis role="strong">-h</emphasis> (or <emphasis role="strong">--help</emphasis>) option which will produce a short usage description of the command and it's options, then exit back to the command prompt. Type <screen>man -h</screen> or <screen>man --help</screen> to see this in action.
