merge-dependabot-pr.sh
#!/bin/bash
# This script creates a consolidate Pull Request for all outstanding dependabot
# Pull Requests.
#
# Motivation: Sometimes, dependabot opens a large number of PRs that all need to
# be merged. Each time one merges, it causes the rest to be out of date, making
# it a slow, manual process of clicking upate, waiting for ci, then clicking
# merge for each subsequent PR.
#
# Usage:
#
# ```bash
# cd MY_GIT_REPO
# merge-dependabot-prs.sh
# ```
#
# TODO: Only merge PRs with a successful CI status
#
# Maintainer: [Ian Remmel](https://github.com/ianwremmel)
#
# Contribution: This gist will be updated based on feedback in the comments, as
# appropriate
