Synopsis

echo -n (prompt_pwd) '$ '
|

end

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
|
|
-------
|
|
|
|
- ``-h`` or ``--help`` displays the help and exits
|
|
- ``-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.
