I found these online and added them to my gitconfig at one point... I can't take credit for them. Integrating fzf with git makes working with branches even better (with fuzzy matches for checking out as well as deleting branches)...

cob = !BRANCH=`git recent --no-color | fzf` && git checkout ${BRANCH}

db = !BRANCH=`git branch --no-color | fzf` && git branch -d ${BRANCH}

dbf = !BRANCH=`git branch --no-color | fzf` && git branch -D ${BRANCH}
