export - compatibility function for exporting variables
=======================================================
Synopsis
--------
.. synopsis::
export
export NAME=VALUE
Description
-----------
``export`` is a function included for compatibility with POSIX shells. In general, the :doc:`set <set>`
builtin should be used instead.
When called without arguments, ``export`` prints a list of currently-exported variables, like ``set
-x``.
When called with a ``NAME=VALUE`` pair, the variable ``NAME`` is set to ``VALUE`` in the global
scope, and exported as an environment variable to other commands.
There are no options available.
Example
-------
The following commands have an identical effect.
::
set -gx PAGER bat
export PAGER=bat
Note: If you want to add to e.g. ``$PATH``, you need to be careful to :ref:`combine the list <cartesian-product>`. Quote it, like so::
export PATH="$PATH:/opt/bin"
Or just use ``set``, which avoids this::
set -gx PATH $PATH /opt/bin
