Search all branches of a Git repo

Recently I couldn't find work I knew I wrote earlier. My only guess was that it was in a branch that wasn't obvious to me. After some googling, I came across this SO post that demonstated searching all branches of a repo.

Example

  git grep "Your string or Regexp" $(git rev-list --all)

Additional tip

The results of the above search will provide commit hashes and file names. Use the hash to locate the branch that contains the change be running:

  git branch --contains XXXXXXXXXXXXXXXXXX
