Handy script when you're moving a git repo from one github owner to another

git-chown

#!/bin/bash -e

# Usage:
#  $ git chown <repo name> <old owner> <new owner>
# Example:
#  $ git chown lineman testdouble linemanjs

REPO_NAME=$1
OLD_OWNER=$2
NEW_OWNER=$3
SED_PATTERN="s/$OLD_OWNER\/$REPO_NAME/$NEW_OWNER\/$REPO_NAME/g"

echo "--> searching for '$OLD_OWNER/$REPO_NAME' and replacing with '$NEW_OWNER/$REPO_NAME'"
git grep -l "$OLD_OWNER/$REPO_NAME" | xargs sed -i .gitchownbk "$SED_PATTERN"

echo "--> altering any git remotes' URLs"
sed -i .gitchownbk "$SED_PATTERN" .git/config

echo "--> cleaning out sed's backup files (*.gitchownbk)"
find . -name "*.gitchownbk" | xargs rm

echo "--> remaining references to '$OLD_OWNER' in repo:"
git grep "$OLD_OWNER"
