Hi all, This PR addresses [8333685](https://bugs.openjdk.org/browse/JDK-8333685).
I have added the following enhancements: - Removed uses of `fgrep` and `egrep` with `grep -F` and `grep -E` respectively. - Altered default behaviour to limit the processed changesets to those in the current branch and the current year. - Enabled an option to modify all changesets in the year if desired (this was the previous default behaviour). - Added named parameters and enabled `--help`. - Removed mercurial support. - Fixed a bug where copyright headers that didn't have a comma following the initial year of creation were not getting picked up. For example, [here](https://github.com/openjdk/jdk/blob/512b2b4f141f9a202984150b0427372e1a409a50/src/hotspot/cpu/zero/copy_zero.hpp#L3). - Fixed a bug where copyright headers missing the copyright symbol (c) were not getting picked up. Refer to the example above as well. Thanks, Sonia ------------- Commit messages: - Support for copyright statements missing symbol - 8333685: Make update-copyright-year script more useful Changes: https://git.openjdk.org/jdk/pull/19605/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=19605&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8333685 Stats: 97 lines in 1 file changed: 38 ins; 26 del; 33 mod Patch: https://git.openjdk.org/jdk/pull/19605.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/19605/head:pull/19605 PR: https://git.openjdk.org/jdk/pull/19605
