1、已 Tracked file 状态
The basic Git workflow goes something like this:
- You modify files in your working tree.
- You selectively stage just those changes you want to be part of your next commit, which adds only those changes to the staging area.
- You do a commit, which takes the files as they are in the staging area and stores that snapshot permanently to your Git directory.
2. 文件状态图
3. git status
4. git add hello.java
5. 忽略文件
5.1 查看忽略配置
cat .gitignore
规则
A、空行或以 # 开头的行会被忽略。
B、Standard glob patterns work, and will be applied recursively throughout the entire working tree.
C、
You
can start patterns with a forward slash (/) to avoid recursivity.
You
can end patterns with a forward slash (/) to specify a directory.
You
can negate a pattern by starting it with an exclamation point (!).
6、比较 git diff
6.1 查看未暂存的文件的更改
git diff
6.2 查看已暂存文件的更改
git diff --staged
7、添加文件
git add hello.java
8、删除文件
git rm hello.java
9、提交
git commit -m "提交的注释"
10、移动文件
git mv hello.java HelloWorld.java
11、从暂存区移除文件
git reset docs/*
git reset docs/requirement.docx
