.. _cmd-export:
|
|
|
|
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
|
|
|
|
