Replace black formatter version in several repos (hacky)

replace_black.sh

#!/bin/bash

OIFS=$IFS
IFS="
"
ORIGNAL_BLACK="lgeiger/black-action@master"
NEW_BLACK="tripactions/black-code-formatter@21.4b1"
BRANCH="youri/update_black_code_formatter"

for i in `grep -iER "lgeiger/black-action@master" --include "*.yml" .`
do
  REPO=`echo $i | cut -d "/" -f 2`
  FILE=`echo $i | cut -d ":" -f 1 | sed "s/\.\/${REPO}\///"`

  cd $REPO
  git checkout master
  git pull
  git checkout -b $BRANCH
  git checkout $BRANCH
  sed -i '' -e "s/lgeiger\/black-action\@master/tripactions\/black-code-formatter\@21\.4b1/g" ${FILE}
  git add $FILE
  git commit -m "Pin GA black code formatter to 21.4b1"
  git push origin $BRANCH
  cd ..
