Adds synopses for those commands missing them. Moves all synopsis sections to code blocks. This improves the appearance, although highlighting as fish code may not be the ideal appearance.

Description
|
|
-----------
|
|
|
|
``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 :ref:`function <cmd-function>`.
|
|
|
|
``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``.
|
|
|
|
- ``NAME`` is the name of the alias
|
|
- ``DEFINITION`` is the actual command to execute. The string ``$argv`` will be appended.
|
|
|
|
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*.
|
|
|
|
The following options are available:
|
|
|
|
- ``-h`` or ``--help`` displays help about using this command.
|
|
|
|
- ``-s`` or ``--save`` Automatically save the function created by the alias into your fish configuration directory using :ref:`funcsave <cmd-funcsave>`.
|

Example
|
|
-------
|
|
|
|
The following code will create ``rmi``, which runs ``rm`` with additional arguments on every invocation.
|
|
|
|
|
|
|
|
::
|
|
|
|
alias rmi="rm -i"
|
|
|
|
# This is equivalent to entering the following function:
|
|
function rmi --wraps rm --description 'alias rmi=rm -i'
|
|
rm -i $argv
|
|
end
|
|
|
|
# This needs to have the spaces escaped or "Chrome.app..." will be seen as an argument to "/Applications/Google":
|
|
alias chrome='/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome banana'
