\subsection cd-description Description
`cd` changes the current working directory.
If `DIRECTORY` is supplied, it will become the new directory. If no parameter is given, the contents of the `HOME` environment variable will be used.
If `DIRECTORY` is a relative path, the paths found in the `CDPATH` environment variable array will be tried as prefixes for the specified path.
Note that the shell will attempt to change directory without requiring `cd` if the name of a directory is provided (starting with `.`, `/` or `~`, or ending with `/`).

Fish also ships a wrapper function around the builtin `cd` that understands `cd -` as changing to the previous directory. See also <a href="commands.html#prevd">`prevd`</a>. This wrapper function maintains a history of the 25 most recently visited directories in the `$dirprev` and `$dirnext` global variables. If you make those universal variables your `cd` history is shared among all fish instances.
\subsection cd-example Examples
\fish
cd
# changes the working directory to your home directory.
cd /usr/src/fish-shell
# changes the working directory to /usr/src/fish-shell
\endfish
