变革后提交挂钩以触发仓库导出到其他目录

Question

我正在尝试为svn编写一个post commit hook脚本，以便将存储库导出到多个目录（因此，当您提交代码时，最新版本的代码也会被复制到其他目录）。例如，我有一个repo，它有4个路径（或目录）a、B、C、D。我希望如果我在a中提交，那么修订也应该转到B、C、D。同样地，如果我在B中提交，那么修订应该转到C、D，同样地，当在C上提交时，它应该反映在D上

我开始了解post commit，但不知道如何使用它。我已经写了这一堆代码，这是部分工作。i、 e当我在A中提交时，它转到B而不是C或D，同样地，当我在B上提交时，它转到C而不是D

我以前没有写过脚本。我做了一个测试回购测试来测试我的工作。你知道吗

现在它完成了预期的工作！！你知道吗
