如何使本地 ~/bin 文件夹与来自各个 Github 存储库的更新保持同步？

~/bin包含我从各种 Github 存储库下载的许多脚本，而 Ubuntu 默认存储库没有提供这些脚本的最新版本和/或不存在 PPA。

有什么好方法可以保留所有这些脚本自动地是否保持最新并与各自 Github 存储库中的最新版本同步？

答案1

简单的解决方案

您实际上要做的是git fetch && git pull从每个存储库文件夹内部运行~/bin。最简单的方法是将此命令添加到启动应用程序：

find /home/user/bin  -type d -exec sh -c 'cd {} && git fetch && git pull' \;  2> /dev/null

请注意，这/home/user/bin必须是您的~/bin文件夹的完整路径。

Python 脚本

但是，如果您想要一个专用实用程序来完成此任务，这里有一个 Python 脚本，它可以递归更新您的所有内容~/bin。使用方法很简单 - 从终端运行它，python git_updater.py它会处理其余的事情。甚至可以将同一命令作为启动应用程序的条目添加到每次登录时运行脚本

脚本源代码如下，也可以在我的GitHub 存储库。
