From the name and description, I expected this to perform operations on file path strings, like convert relative to absolute (and vice versa), expand symlinks, convert unix paths to dos, etc. This is more like a find command.
I don't see why it necessarily couldn't, my only question would be if there are really many actual use cases for such things? As far as symlinks go, I suppose being able to expand them (but not following them!) might be somewhat useful. But converting to DOS paths and vice-versa? That just doesn't seem very useful. Nevermind converting to-and-fro relative and absolute paths, I can't even imagine what the point of that would be. But perhaps I'm just not seeing the forest for the trees, as they say.
As a rule of thumb I always make paths absolute when handling files in scripts. But then sometimes I need to copy a directory tree relative to $CWD somewhere else, so I convert them back to relative
Fish, being a great shell, provides this via `path` command[0]
