# export - compatibility function for exporting variables

## Synopsis

    export
    export NAME=VALUE

## Description

`export` is a function included for compatibility with POSIX shells. In general, the 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 combine the list. Quote it, like so:

    export PATH="$PATH:/opt/bin"

Or just use `set`, which avoids this:

    set -gx PATH $PATH /opt/bin
