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.

O comportamento padrão para um comando pode normalmente ser modificado colocando-se <command>--option</command> depois dele. Por exemplo, o comando <link linkend="ls"><command>ls</command></link> tem uma opção <command>-s</command>. O comando <command>ls -s</command> irá incluir tamanhos dos arquivos à listagem. Há também uma opção <command>-h</command> para exibir tamanhos dos arquivos em um formato <quote>legível por humanos</quote>.

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>

Opções podem ser agrupadas, assim, <screen>ls -sh</screen> é o mesmo que usar o comando <screen> ls -s -h</screen> A maioria das opções tem uma versão longa, prefixada com dois traços em vez de um, assim <screen>ls --size --human-readable</screen> faz o mesmo que o comando <screen>ls -sh</screen>

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

Every command and nearly every application in Linux has a <abbrev>man</abbrev> (manual) file. It is as simple as typing <command>man command</command> to bring up a longer manual entry for the specified command. For example: <screen>man mv</screen> brings up the <command>mv</command> manual.

Cada comando e quase toda aplicação no Linux tem uma página <abbrev>man</abbrev> (manual). É só digitar <command>man comando</command> para ver uma longa entrada de manual para o comando especificado. Por exemplo: <screen>man mv</screen> traz o manual de <command>mv</command>.

There are also <command>info</command> pages, which generally go into more detail than <command>man</command> pages. Try: <screen>info info</screen> for the introduction to info pages.
