create_commit() {
    git checkout "$1"
    echo "$2" > src.txt
    git commit -am "$2"
    git log --graph --pretty=format:'%s %C(yellow)%d%Creset'

mkdir test && cd test/
git init

# inital commit
echo "A" > src.txt
git add -- src.txt
git commit -am "A"
git log --graph --pretty=format:'%s %C(yellow)%d%Creset'

git checkout -b feature1
git checkout master
git checkout -b feature2

# two programmers working at the same time

create_commit feature2 "D"
create_commit feature1 "C"
