Psh::Builtins::Export(3p)

•   "export VAR [=VALUE]"

    Just like setenv, below, except that it also ties the variable (in the Perl sense) so that subsequent changes to the variable automatically affect the environment. Variables who are lists and appear in option 'array_exports' will also by tied to the array of the same name. Note that the variable must be specified without any Perl specifier like "$" or "@".
