## :cd

Arguments: &optional dir

This command and the related :popd and :pushd work just like their Unix C shell counterparts. :cd changes the current directory to dir (if supplied) or to the user's home directory (if dir is not supplied). On Windows, the home directory is taken to be C:\. :pushd changes the current directory to dir and adds it to the directory stack. If no argument is supplied, :pushd changes to the directory at the top of the directory stack and swaps the top two directories on the stack. :popd pops the current directory off the directory stack and changes the current directory to the directory that was next on that stack.

:cd, :popd, and :pushd all change the value of `*default-pathname-defaults*` so that its directory component is the new current directory.

dir will be treated as a string but need not be surrounded in quotation marks.

See also chdir (which is like :cd but does not change the value of `*default-pathname-defaults*`) and current-directory.

See also :dirs, which prints the stack of directories and :pwd, which prints the full path of the current directory.

:cd has no abbreviation.
