.. _cmd-realpath:

realpath - convert a path to an absolute path without symlinks
==============================================================

Synopsis
--------

::

    realpath PATH

Description
-----------

``realpath`` resolves a path to its absolute path.

fish provides a ``realpath`` builtin as a fallback for systems where there is no ``realpath`` command, your OS might provide a version with more features.

If a ``realpath`` command exists, it will be preferred, so if you want to use the builtin you should use ``builtin realpath`` explicitly.

The following options are available:

- ``-s`` or ``--no-symlinks``: Don't resolve symlinks, only make paths absolute, squash multiple slashes and remove trailing slashes.

builtin realpath: Add --no-symlinks option Taken from GNU realpath, this one makes realpath not resolve symlinks. It still makes paths absolute and handles duplicate and trailing slashes.

fish_add_path: Don't resolve symlinks The case for symlinked directories being duplicated a lot isn't there, but there is a usecase for adding the symlink rather than the target, and that's homebrew. E.g. homebrew installs ruby into /usr/local/Cellar/ruby/2.7.1_2/bin, and links to it from /usr/local/opt/ruby/bin. If we add the target, we would miss updates. Having path entries that point to the same location isn't a big problem - it's a path lookup, so it takes a teensy bit longer. The canonicalization is mainly so paths don't end up duplicated via weird spelling and so relative paths can be used. 2020-09-13 01:28:01 +08:00			- ``-s`` or ``--no-symlinks``: Don't resolve symlinks, only make paths absolute, squash multiple slashes and remove trailing slashes.
