Thanks for tackling this.

When it will work, it will be very useful, but so far I did not get it to work on my Mac m1.

It identifies the commits correctly that are part of the delta to master, as it should. But it does not modify any copyrights. I tracked this down to the sed's in updateFile not doing anything.

I tried the script on this branch: https://github.com/tstuefe/jdk/tree/do-some-stuff-in-aix and called the script without command line args. It should have found and fixed the Oracle copyrights in osThread_aix.xxx

For reference, this is how the expanded sed arguments look like:


s@(Copyright ((c) )?[12][0-9][0-9][0-9],) [12][0-9][0-9][0-9], Oracle@\1 2024, Oracle@
s@(Copyright ((c) )?[12][0-9][0-9][0-9],) Oracle@\1 2024, Oracle@
s@(Copyright ((c) )?[12][0-9][0-9][0-9]) Oracle@\1, 2024, Oracle@
s at Copyright 2024, 2024, Oracle at Copyright 2024, Oracle@
s at Copyright (c) 2024, 2024, Oracle at Copyright (c) 2024, Oracle@
