<p>In <a href="Computing" title="Computing">computing</a>, a <b>command</b> is an instruction received via an external <a href="Interface_(computing)" title="Interface (computing)">interface</a> that directs the behavior of a <a href="Computer_program" title="Computer program">computer program</a>. Commonly, commands are sent to a program via a <a href="Command-line_interface" title="Command-line interface">command-line interface</a>, a <a href="Scripting_language" title="Scripting language">script</a>, a <a href="Network_protocol" class="mw-redirect" title="Network protocol">network protocol</a>, or as an event triggered in a <a href="Graphical_user_interface" title="Graphical user interface">graphical user interface</a>.
</p><p>Many commands support arguments to specify input and to modify default behavior. Terminology and syntax varies but there are notable common approaches. Typically, an <b>option</b> or a <b>flag</b> is a name (without <a href="Whitespace_character" title="Whitespace character">whitespace</a>) with a prefix such as <a href="Dash" title="Dash">dash</a> or <a href="Slash_(punctuation)" title="Slash (punctuation)">slash</a> that modifies default behavior. An option might have a required value that follows it. Typically, flag refers to an option that does not have a following value. A <b>parameter</b> is an argument that specifies input to the command and its meaning is based on its position in the command line relative to other parameters; generally ignoring options. A parameter can specify anything, but often it specifies a <a href="File_(computing)" class="mw-redirect" title="File (computing)">file</a> by <a href="Filename" title="Filename">name</a> or <a href="File_path" class="mw-redirect" title="File path">path</a>.
</p><p>The term <i>command</i> is sometimes also used for internal program instructions, but often other terms are more appropriate such as <a href="Statement_(programming)" class="mw-redirect" title="Statement (programming)">statement</a>, <a href="Expression_(computer_science)" title="Expression (computer science)">expression</a>, <a href="Function_(computer_programming)" title="Function (computer programming)">function</a>, or <a href="Conditional_(computer_programming)" title="Conditional (computer programming)">conditional</a>.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> For example, printing a message in Bash is via the <i>command</i> <a href="Printf_(Unix)" title="Printf (Unix)">printf</a>, while in Python it is via the <i>function</i> print().<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> Further, some aspects of adjacent technology are conflated with commands. For example, conditional logic in Bash and Python is called an <i>expression</i><sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> and <i>statements</i> in Java.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup>
</p>
<meta property="mw:PageProp/toc">
<div class="mw-heading mw-heading2"><h2 id="Examples">Examples</h2></div>
<p>A notable context in which commands are prevalent is the <a href="Operating_system" title="Operating system">operating system</a> <a href="Shell_(computing)" title="Shell (computing)">shell</a>. Commonly, the shell dispatches a command to a program that has a file name matching the first parameter. In a <a href="Unix_shell" title="Unix shell">Unix shell</a> (such as <a href="Bash_(Unix_shell)" title="Bash (Unix shell)">bash</a> and many related variants), the match must be exact including case. The following bash command changes the <a href="Working_directory" title="Working directory">working directory</a> to <i>/home/pete</i> by invoking the program <i><a href="Cd_(command)" title="Cd (command)">cd</a></i>:
</p>
<div class="mw-highlight mw-highlight-lang-bash mw-content-ltr" dir="ltr"><pre><span class="nb">cd</span><span class="w"> </span>/home/pete
</pre></div>
<p>The following bash command writes "Hello World" via program <a href="Echo_(command)" title="Echo (command)">echo</a> to <a href="Standard_output" class="mw-redirect" title="Standard output">standard output</a> – typically the <a href="Computer_terminal" title="Computer terminal">terminal</a>. Quotes around the two words indicate that the phrase is treated as a single parameter.
</p>
<div class="mw-highlight mw-highlight-lang-bash mw-content-ltr" dir="ltr"><pre><span class="nb">echo</span><span class="w"> </span><span class="s2">"Hello World"</span>
</pre></div>
<p>The following demonstrates how the default behavior of a command is modified with a switch. The switch <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">-e</code> causes the command to treat characters prefixed with a backslash as the associated control character. In this case <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">\t</code> results in a tab character.
</p>
<div class="mw-highlight mw-highlight-lang-bash mw-content-ltr" dir="ltr"><pre><span class="nb">echo</span><span class="w"> </span>-e<span class="w"> </span><span class="s2">"Hello\tWorld"</span>
</pre></div>
<p>In shells such as <a href="Cmd.exe" title="Cmd.exe">command prompt</a>, <a href="DOS" title="DOS">DOS</a>, and <a href="OS/2" title="OS/2">OS/2</a> some commands are built-in; are not implemented as a separate program. But, if a command is not built-in, then the shell dispatches to a program that has an executable extension (such as <i>.exe</i>) and base name matching the first parameter ignoring case. The following command prompt command displays the content of file <i>readme.txt</i> via the built-in command <i><a href="TYPE_(DOS_command)" title="TYPE (DOS command)">type</a></i>.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup>
</p>
<div class="mw-highlight mw-highlight-lang-batch mw-content-ltr" dir="ltr"><pre><span class="k">type</span> readme.txt
</pre></div>
<p>The following command prompt command lists the contents of the current directory via built-in command <i><a href="Dir_(command)" title="Dir (command)">dir</a></i>. The switch <i>/Q</i> modifies default behavior to include owner information.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>
</p>
<div class="mw-highlight mw-highlight-lang-batch mw-content-ltr" dir="ltr"><pre><span class="k">dir</span> /Q
