Question

Tracking a single remote branch as a local branch is straightforward enough.

$ git checkout --track -b ${branch_name} origin/${branch_name}

Answer 1

In case you already have some branches checked out and want to

• check out all remaining branches from the remote
• make sure all local branches track the remote branches

you can use the following bash- and zsh-compatible script:

git branch -r | while read b; do if git branch | grep -q " ${b##*/}$"; then git branch --set-upstream ${b##*/} $b; else git branch --track ${b##*/} $b; fi; done
