The ./brew-update-pr.sh script in this directory updates the brew formula for librdkafka and pushes a PR to the homebrew-core repository.
You should run it in two steps, first an implicit dry-run mode to check that things seem correct, and if that checks out a live upload mode which actually pushes the PR.
# Do a dry-run first, v0.11.0 is the librdkafka tag: $ ./brew-update-pr.sh v0.11.0 # If everything looks okay, run the live upload mode: $ ./brew-update-pr.sh --upload v0.11.0
