The scripts were attributed to LINUXexpert.org, which is being retired as a site and is no longer where this work lives. Coffey Labs is the organisation these projects belong to. One line per script, fifteen of them, and nothing else. LICENSE is deliberately untouched: its "Copyright (C) <year> <name of author>" lines are GPL boilerplate showing you how to write your own notice, and the Free Software Foundation's own copyright on the licence text is not ours to edit. Both git contributors are the same person, so there is no third-party copyright here that could not be restated.
