##### 1.3.5.2 A Sample Command Description

Command descriptions have a format similar to function descriptions, except that the word `Function' is replaced by `Command'. Commands are functions that may be called without surrounding their arguments in parentheses. For example, here is the description for Octave's `cd` command:

— Command: cd dir
— Command: chdir dir

> Change the current working directory to dir. For example, `cd ~/octave` changes the current working directory to `~/octave`. If the directory does not exist, an error message is printed and the working directory is not changed.
