# prompt_pwd - print pwd suitable for prompt

## 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 `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 `$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 `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 `fish_prompt_pwd_full_dirs`.

-h or --help

  Displays help about using this command.
