Simple script to transfer multiple repos from Bitbucket to GitHub (or vice versa). Inspired by https://stackoverflow.com/a/21260628/922323

xfer-repos-from-bitbucket-to-github.sh

#!/usr/bin/env bash

# This script assumes you have your ssh keys setup for Bitbucket and GitHub.
# It also assumes you have created the repos on GitHub already and the URL slugs are an exact match.
# Also, this script will barf if you try to transfer an empty repo.
# Note that this code does not transfer wikis, downloads or issues.
# Also note, you may have to turn on QOS upload speed limiting so your router
# doesn’t freak out; I limited my upload bandwidth to 2Mbps.
# Don’t forget to `chmod u+x <this file>.sh` in order to execute it via `./<this file>.sh`.

declare -r bitbucket_user=
declare -r github_user=
declare -r xfer_from=bitbucket.org
declare -r xfer_to=github.com

# Explicitly declare a variable (this is better than implicit):
declare -a repos=(
  "foo"
  "baz"
  "bar"
  "other"
)

for i in "${repos[@]}"; do
  echo Transfering repo: "$i"
  git clone --bare git@${xfer_from}:${bitbucket_user}/${i}.git
  cd ${i}.git || exit
  git push --mirror git@${xfer_to}:${github_user}/${i}.git
  cd - || exit
done

# Gracefully Exit program:
exit 0
