Pass (export) the value of one or more shell variables, giving global meaning to the variables (which are local by default). For example, a variable defined in one shell script must be exported if its value will be used in other programs called by the script. When a shell variable has been exported, you can access its value by referencing the equivalent environment variable. If no variables are given, export lists the variables exported by the current shell. If name and value are specified, export assigns value to a variable name and exports it.

Options

Treat all subsequent strings as arguments, not options.
