Commands are functions that may be called without surrounding their arguments in parentheses. For example, here is the description for Octave's <code>cd</code> command: <div class="defun"> — Command: <b>cd</b><var> dir<a name="index-cd-25"></a></var><br> — Command: <b>chdir</b><var> dir<a name="index-chdir-26"></a></var><br> <blockquote><p>Change the current working directory to <var>dir</var>. For example, <kbd>cd ~/octave</kbd> changes the current working directory to <samp><span class="file">~/octave</span></samp>. If the directory does not exist, an error message is printed and the working directory is not changed. </p></blockquote></div> </body></html>
