``alias`` is a simple wrapper for the ``function`` builtin, which creates a function wrapping a command. It has similar syntax to POSIX shell ``alias``. For other uses, it is recommended to define a `function <cmds/function.html>`__.
``fish`` marks functions that have been created by ``alias`` by including the command used to create them in the function description. You can list ``alias``-created functions by running ``alias`` without arguments. They must be erased using ``functions -e``.
You cannot create an alias to a function with the same name. Note that spaces need to be escaped in the call to ``alias`` just like at the command line, *even inside quoted parts*.
-``-s`` or ``--save`` Automatically save the function created by the alias into your fish configuration directory using `funcsave <cmds/funcsave.html>`__.
