机器 A 有 Internet 连接，而机器 B 没有。两者都有本地存储库，机器 A 可以与 Github 交互。开发在两台机器上进行。git-bundle 用于使存储库保持同步。

通常的同步流程：

  1. 创建 B 中所有分支的捆绑包并将捆绑包转移到 A。

  2. 在 A 上克隆 github 存储库。将 bundle 中的所有分支拉到从 github 克隆的存储库中。将更新的存储库（所有分支）推送到 github。

  3. 从 github 存储库创建所有分支的捆绑包。将捆绑包转移到 B。将捆绑包中的所有分支拉入 B 上的存储库。

有一种方法可以创建存储库所有分支的捆绑包。但是有没有办法一次将包的所有分支拉到本地存储库中？

在单分支存储库的情况下，双向同步似乎是直截了当的。

由于包与任何其他存储库一样 - 唯一的区别是包恰好存储为单个文件 - 您可以使用从包git pull --all中获取所有分支并将它们合并到相应的跟踪分支中：

git pull --all /path/to/bundle

但是请注意，该--all选项仅适用于git fetch. 这意味着只有当前本地分支（即由 引用的分支HEAD）将被更新。如果您还想更新所有本地分支，则必须自己编写脚本或使用git-up之类的东西。

将以下 pullbundlebranches git 别名添加到您的~/.gitconfig然后运行git pullbundlebranches ../[filename].gitbundle​​.

[alias]
  pullbundlebranches = "!f() { git pull --tags $1; git fetch $1; git bundle verify $1 | grep ' refs/heads/' | (while read line; do \
    commit=`echo $line | cut -d' ' -f1`; branch=`echo $line | sed 's_[^\\ ]*\\ refs/heads/__'`; \
    if git show-ref -q --heads $branch; then \
      old_commit=`git rev-parse $branch`; \
      if [ \"$old_commit\" = \"$commit\" ]; then \
        echo 'Skipping' $branch 'which is up-to-date at' $old_commit; \
      elif git merge-base --is-ancestor $branch $commit; then \
        current_branch=`git rev-parse --abbrev-ref HEAD`; \
        if [ \"$current_branch\" = \"$branch\" ]; then \
          git reset --hard $commit; \
        else \
          git branch -Dq $branch; git branch $branch $commit; \
        fi; \
        echo 'Updated' $branch 'from' $old_commit 'to' $commit; \
      elif git merge-base --is-ancestor $commit $branch; then \
        echo 'Skipping' $branch 'which is ahead of bundle version ('$commit')'; \
      else \
        echo 'Error:' $branch 'already exists and diverges from upstream found in bundle'; \
        echo 'You could switch to the bundle version as follows, but you might lose work.'; \
        echo 'git checkout -B' $branch $commit; \
      fi; \
    else \
      git branch $branch $commit; \
      echo 'Created' $branch 'pointing at' $commit; \
    fi; done); }; f"

它从包中获取，然后尝试更新/创建其中包含的每个分支。如果您自己的分支版本领先或相等，则什么也不做。如果该分支与捆绑包中的版本不同，则会打印一个错误，说明如何切换到捆绑包版本，并且什么也不做。

运行示例，然后强制分支到捆绑包中的版本，然后再次重新运行，但什么都不做：

$ git pullbundlebranches ../../bundles/Jabberwocky_November_snapshot.gitbundle
From ../../bundles/Jabberwocky_November_snapshot.gitbundle
 * branch              HEAD       -> FETCH_HEAD
../../bundles/Jabberwocky_November_snapshot.gitbundle is okay
Error: develop already exists and diverges from upstream found in bundle
You could switch to the bundle version as follows, but you might lose work.
