Requirements

• The local repo can have changes
• The branch or tag can be updated

I wrote a code like below, but I think there will be more clean answer. Any suggestion?

(For a tag, the last git reset ... is useless. It's for a branch)

git fetch && git fetch --tags && \ 
git checkout -- . && \
git checkout branch_or_tag && \
git reset --hard origin/branch_or_tag
