.zshrc

gbDi() {
  git branch --sort=-committerdate | remove-colors | egrep -v "master|\*" | cut -c3- > /tmp/branches && \
    cp /tmp/branches /tmp/branches-to-keep && \
    vim /tmp/branches-to-keep && \
    comm -23 <(sort /tmp/branches) <(sort /tmp/branches-to-keep) | xargs 2> /dev/null git branch -D
}

remove-colors() {
  sed -r "s/\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[m|K]//g"
