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
