Script for adding same file to all repositories in a organization as a pull request (works in 2024)

pr_with_the_file_on_every_repo.sh

#!/usr/bin/env bash

#
# How it works
# - clone all repositories using `gh-cli`
# - copy the prepared file to one repo among them
# - git add, git commit, git push, gh pr create
# - Repeat above two steps for other repos
#


# Step 0. Prepare empty folder and copy the target file into the folder

mkdir -p tmp_for_all_pr
cd tmp_for_all_pr
copy ../pull_request_template.md ./pull_request_template.md


# Step 1. Clone all repositories

ORG_NAME="my-org"
MAX_COUNT=500

# No forked repo, no archived repo
repos=$(gh repo list $ORG_NAME --limit $MAX_COUNT --source --no-archived --json url --jq ".[].url")

for repo in $repos
do
    git clone $repo
done


# Step 2. Add file and make a pull_request to each repositories

for dir in $(ls -d */); do 
    dir=${dir%*/}
    dir=${dir##*/}
    mkdir -p $dir/.github # make sure the folder exist
    cp pull_request_template.md $dir/.github/pull_request_template.md # copy the file to target folder
    cd $dir # *splash*
    git pull
    git checkout -b feat/pull-request-template
    git add .github/pull_request_template.md
    git commit -m "feat: Apply pull request template"
    git push --set-upstream origin feat/pull-request-template

    # I don't specify the base branch because not every repo has the same default branch name
    # Without --base parameter, Each pr heads to the base branch of its repo
    gh pr create --title "feat: Apply pull request template" --body "" 
    cd .. # *hsalps*
done

By the way, check if the org has a repo named .github. You probably want to exclude it.
