此命令的作用是“git checkout -- .”

Question

我是使用 git 的初学者，我想知道这个 git 命令是什么意思

git checkout -- .

我知道 git checkout 用于在分支机构之间切换，但我不知道上面的选项意味着什么我试图查看 toturials 但我没有这样的选项

Answer 1

-- 和 . 都不是 git 特定的：

The first -- argument that is not an option-argument should be accepted as a delimiter indicating the end of options. Any following arguments should be treated as operands, even if they begin with the '-' character.

（来自 https://unix.stackexchange.com/questions/11376/what-does-double-dash-mean-also-known-as-bare-double-dash/11378）。

. 是当前目录。

git checkout is for switching between branches

如果您查看 https://git-scm.com/docs/git-checkout，此命令的格式为

git checkout [<tree-ish>] [--] <pathspec>…

原来如此

Overwrite[s] paths in the working tree by replacing with the contents in the index or in the <tree-ish> (most often a commit).

"Paths" 是 . （当前目录）并且 "the <tree-ish>" 是 HEAD （当前提交 Git 指向），因为你没有t指定另一个。

Answer 2

tymtam@x:/mnt/c/tmp/x$ git status

        modified:   x.txt
        modified:   z/z1.txt
        modified:   z/z2/z2_1.txt

tymtam@x:/mnt/c/tmp/x$ cd z                // changing to subdirectory
tymtam@x:/mnt/c/tmp/x/z$ git checkout -- .
tymtam@x:/mnt/c/tmp/x/z$ git status

        modified:   ../x.txt

（为简洁起见，我删除了 git 喋喋不休的内容）

此命令的作用是“git checkout -- .”

What does this Command do " git checkout -- . "

git

git-checkout
