Fetch and pull all branches from origin

.bash

#!/bin/bash
for branch in `git branch -a | grep remotes | grep -v HEAD | grep -v master`; do
    git branch --track ${branch##*/} $branch
done
git fetch --all
git pull --all

one line solution:

git branch -a | grep -v HEAD | perl -ne 'chomp($_); s|^\*?\s*||; if (m|(.+)/(.+)| && not $d{$2}) {print qq(git branch --track $2 $1/$2\n)} else {$d{$_}=1}' | csh -xfs
