This gist lists the cherry pick by author and stores in a file and apply it on a branch

cherry-pick-by-author.sh

#!/usr/bin/env bash
if [ -z ${1} ]
then
    echo "Enter first argument which is author name";
    exit
fi
if [ -z {$2} ]
then 
    echo "enter second argument which is in which branch you want these commits to go"
    exit
fi

echo "Cherry picking commit for user ${1} from branch $(git symbolic-ref --short -q HEAD) will put into ${2}" ;

git log --committer="saras.arya@rentomojo.com" --format=format:%H > cherry-pick.txt
git checkout ${2}
for commit in $(cat cherry-pick.txt) ; do
  hash=$(echo ${commit} | cut -d$'\t' -f 1)
  printf "${hash}\n"
  git cherry-pick ${hash}
  done

You might want to consider on line 17 tac instead of cat? That way it will apply the changes in the order the developer did.

@biemster that is a very interesting point, for that matter. I didn't even know there was a command called tac.

I just used this gist to save a week of my work on a branch I wrecked (thanks for this!), but it only managed to successfully apply the hashes in the correct order, so using tac. Thanks again!
