    prompt_pwd

Description
-----------

``prompt_pwd`` is a function to print the current working directory in a way suitable for prompts. It will replace the home directory with "~" and shorten every path component but the last to a default of one character.

To change the number of characters per path component, pass ``--dir-length=`` or set :envvar:`fish_prompt_pwd_dir_length` to the number of characters. Setting it to 0 or an invalid value will disable shortening entirely. This defaults to 1.

To keep some components unshortened, pass ``--full-length-dirs=`` or set :envvar:`fish_prompt_pwd_full_dirs` to the number of components. This defaults to 1, keeping the last component.

If any positional arguments are given, ``prompt_pwd`` shortens them instead of :envvar:`PWD`.

Options
-------

**-d** or **--dir-length** *MAX*
    Causes the components to be shortened to *MAX* characters each. This overrides :envvar:`fish_prompt_pwd_dir_length`.

**-D** or **--full-length-dirs** *NUM*
    Keeps *NUM* components (counted from the right) as full length without shortening. This overrides :envvar:`fish_prompt_pwd_full_dirs`.

**-h** or **--help**
    Displays help about using this command.
