# track all remote branches:
git branch -r | grep -v '\->' | while read remote; do git branch --track "${remote#origin/}" "$remote"; done
# update all local copies of remote branches
git fetch --all
# update all local tracking branches
git pull --all

git branch -r

git fetch --all

You can fetch all branches from all remotes like this:
git fetch --all

git branch -r

$ git branch -a. If you require only listing the remote branches from Git Bash then use this command:
$ git branch -r. You may also use the show-branch command for seeing the branches and their commits as follows:
$ git show-branch.
