git - git 的版本库根路径的语法是什么？

Question

当使用 git add -u 时，我可以提供一个路径作为最后一个参数，例如git add -u .。如何提供存储库根路径？

我想用它来快速将对跟踪文件的所有更改添加到索引中，包括对目录树更上层文件的更改。

示例

$ git status# On branch mul# Changes not staged for commit:#   (use "git add ..." to update what will be committed)#   (use "git checkout -- ..." to discard changes in working directory)##       modified:   ../../../foo.mwb#no changes added to commit (use "git add" and/or "git commit -a")

Answer 1

冒号:在这里有帮助，您可以通过 :/ 引用存储库的根目录:

git init test
cd test
mkdir a
touch a/a
git add a
git commit -m a
# Here comes the interesting part:
cd a
touch ../root
git add :/
git commit -m root

上面的脚本初始化了一个玩具存储库，其中包含一个文件 a在子目录中 a .在“有趣的部分”中，它变为 a目录，在存储库的根目录中创建一个空文件并使用 :/ 添加它引用。 -u开关照常工作(未在脚本中显示)。

manual of git-rev-parse 阅读:

<rev>:<path>, e.g. HEAD:README, :README, master:./README

A suffix : followed by a path names the blob or tree at the given path in the tree-ish object named by the part before the colon. :path (with an empty part before the colon) is a special case of the syntax described next: content recorded in the index at the given path. A path starting with ./ or ../ is relative to the current working directory. The given path will be converted to be relative to the working tree’s root directory. This is most useful to address a blob or tree from a commit or tree that has the same tree structure as the working tree.

不幸的是，bash自动完成功能不适用于 :/构造。

这related question询问查找存储库的绝对路径；当然你也可以做git add $(git rev-parse --show-toplevel)如 top-voted answer 中所述.
