Git恢复[filename_path]

例如，我需要丢弃我在index.html文件中的最后更改:

git restore /usr/myPC/folder/index.html

This will unstage all files you might have staged with git add: git reset This will revert all local uncommitted changes (should be executed in repo root): git checkout . You can also revert uncommitted changes only to particular file or directory: git checkout [some_dir|file.txt] Yet another way to revert all uncommitted changes (longer to type, but works from any subdirectory): git reset --hard HEAD This will remove all local untracked files, so only git tracked files remain: git clean -fdx WARNING: -x will also remove all ignored files, including ones specified by .gitignore! You may want to use -n for preview of files to be deleted.

总结一下:执行下面的命令基本上相当于从原始源代码复制一个新的git(但它不会重新下载任何东西，所以更快):

git reset
git checkout .
git clean -fdx

典型的使用是在构建脚本中，当你必须确保你的树是绝对干净的——没有任何修改或本地创建的目标文件或构建工件，并且你想让它工作得非常快，而不是每次都重新克隆整个存储库。

还有git stash——它可以“存储”你的本地更改，可以在以后重新应用，也可以在不再需要时删除

更多关于存储的信息

如果你想“撤销”所有未提交的更改，只需运行:

git stash
git stash drop

如果您有任何未跟踪的文件(通过运行git状态检查)，可以通过运行以下命令删除:

git clean -fdx

Git stash创建一个新的stash，它将成为stash@{0}。如果你想先检查一下，你可以运行git stash list来查看你的存储列表。它看起来像这样:

stash@{0}: WIP on rails-4: 66c8407 remove forem residuals
stash@{1}: WIP on master: 2b8f269 Map qualifications
stash@{2}: WIP on master: 27a7e54 Use non-dynamic finders
stash@{3}: WIP on blogit: c9bd270 some changes

每个存储都以前一个提交消息命名。

对于那些到达这里搜索是否可以撤消git clean -f -d的人，通过它在eclipse中创建的文件被删除，

你也可以在UI中使用“restore from local history”为ref: restore from local history进行同样的操作

国家从一个承诺过渡到新的承诺

0. last commit,i.e. HEAD commit
1. Working tree changes, file/directory deletion,adding,modification.
2. The changes are staged in index
3. Staged changes are committed

状态转换的动作

0->1: manual file/directory operation
1->2: git add .
2->3: git commit -m "xxx"

检查差异

0->1: git diff
0->2: git diff --cached
0->1, and 0->2: git diff HEAD
last last commit->last commit: git diff HEAD^ HEAD

恢复到上次提交

2->1: git reset
1->0: git checkout .     #only for tracked files/directories(actions include modifying/deleting tracked files/directories)
1->0: git clean -fdx     #only for untracked files/directories(action includes adding new files/directories)
2->1, and 1->0: git reset --hard HEAD

相当于git的克隆，没有重新下载任何东西

git reset && git checkout . && git clean -fdx
