.. _cmd-prompt_pwd:
prompt_pwd - print pwd suitable for prompt
==========================================
Synopsis
--------
.. synopsis::
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 $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.
