cd [DIRECTORY]
\endfish

\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.

limit size of cd history to 25 directories The existing implementation grows the $dirprev array without bounds. Besides causing what would appear to be a memory leak it also makes the nextd and prevd commands more expensive than they need to be. It also makes it harder to create a useful "menu" cd command. In addition to implementing a reasonable limit on the size of the $dirprev array I've reformatted the code using fish_indent. Update the documentation to include mentions of the $dirprev and $dirnext variables as well as the limit on how much directory history is kept.
