如果我想查看其他分支上有哪些补丁，可以指定一个替代分支：
$ gitlog recovery24
gitlog.id仅显示补丁SHA1 ID：
$ gitlog.id

同样，它假定当前分支，但是我可以根据需要指定其他分支。
gitlog.id2与gitlog.id相同，但顶部没有分支行。 这对于从一个分支到当前分支挑选所有补丁非常方便：
$ # create a new branch
$ git branch --track origin/master
$ # check out the new branch I just created
$ git checkout recovery26
$ # cherry-pick all patches from the old branch to the new one
$ for i in `gitlog.id2 recovery25` ; do git cherry-pick $i ;done
git bash安装教程？ gitlog.grep在该补丁集合中搜寻字符串。 例如，如果我发现一个错误并想修复具有对inode_go_sync函数的引用的补丁程序，则只需执行以下操作：
$ gitlog.grep inode_go_sync

因此，现在我知道补丁HEAD〜9是需要修复的补丁。 我使用git rebase -i HEAD〜10编辑补丁9， git commit -a --amend ，然后git rebase --continue进行必要的调整。
gitbranchcmp3使我可以将当前分支与另一个分支进行比较，因此我可以将较旧版本的补丁与我的较新版本进行比较，并快速查看已更改和未更改的内容。 它会生成一个比较脚本（也使用KDE工具Kompare ，该工具也可在GNOME3上使用）以比较不太相同的补丁。 如果行号以外没有其他差异，则打印[SAME] 。 如果仅注释差异，则打印[相同] （小写）。 例如：
$ gitbranchcmp3 recovery24
Branch recovery24 has 47 patches
Branch recovery25 has 50 patches

最后，我有一个gitlog.find ，一个脚本来帮助我识别补丁程序的上游版本在哪里以及每个补丁程序的当前状态。 它通过匹配补丁说明来实现。 它还会生成一个比较脚本（再次使用Kompare），以将当前补丁与上游对应补丁进行比较：

修补程序显示在两行中，第一行是您当前的修补程序，然后是相应的上游修补程序，以及2个字符的缩写，以指示其上游状态：
我的一些脚本根据我通常使用Git的方式做出假设。 例如，当搜索上游补丁时，它使用我众所周知的Git树的位置。 因此，您将需要调整或改进它们以适合您的条件。 gitlog.find脚本旨在仅定位GFS2和DLM修补程序，因此，除非您是GFS2开发人员，否则您将需要对其进行自定义，使其适合您感兴趣的组件。
git bash配置？ 这是这些脚本的来源。
