Options

74.

The default behavior for a command may usually be modified by adding <command>--option</command> to the command. For example, the <link linkend="ls"><command>ls</command></link> command has an <command>-s</command> option. The <command>ls -s</command> will include file sizes in the listing. There is also a <command>-h</command> option to display file sizes in a <quote>human readable</quote> format.

75.

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