prompt\_pwd
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.
-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.
