#!/usr/bin/env perl
##### git-matching-branches #####
# aws codebuild checks out webhook payloads in a detached head state
# This script looks for branches whose head is the same ref as HEAD
# It prints the short branch names, newline separated, and should play nicely with xargs
# e.g. ./git-matching-branches | xargs -n1 -I '{}' cp tarball_version.tar.gz tarball_version-'{}'.tar.gz
# N.B. Branches whose name does not satisfy semver 2.0.0 item 9 will cause this script to exit abnormally
# and probably break the build [0-9A-Za-Z.-]
You can’t perform that action at this time.
