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.
