Improve checking out branches in git via fzf

git-checkout-fzf.sh

# Description:
# 1. Check if inside git repository.
# 2. If so list all branches except the current including its remote equivalent.
# 3. Remove duplicates that are both local and remote.
# 4. Send it to fzf, and checkout the branch chosen from there.

git config --global alias.co '! git rev-parse --is-inside-work-tree > /dev/null 2>&1 && git branch -a | sed -e "\,HEAD\|$(git branch --show-current),d" | sed "s,remotes/origin/,," | sort | uniq | fzf | xargs -r git checkout'

# Here's a cowsay/lolcat version for the adventurous:
# git config --global alias.co '! a=$(git rev-parse --is-inside-work-tree > /dev/null 2>&1 && git branch -a | sed -e "\,HEAD\|$(git branch --show-current),d" | sed "s,remotes/origin/,," | sort | uniq | fzf | xargs -r git checkout); [ -n "$a" ] && echo "$a" | cowsay -n | lolcat'
