Git alias:
bsd = "!f(){ \
branch=\"${1:-$(git rev-parse --abbrev-ref HEAD 2>/dev/null)}\"; \
git config \"branch.$branch.description\"; \
};f"
Example:
git bsd
This is an example branch
We advocate for git authors to add this feature in the future as
git --show-description
Compare git bed in order to edit the branch description.
