Git学习总结

1.安装git

以Windows为例,安装msysgit,官网地址https://gitforwindows.org/。msysgit以命令行操作为主,图形化操作TortoiseGit后续总结。

 

2. 创建版本库

选定一个目录,右键选中“GIT Bash Here”,会出现命令行(本机示例为路径为E:\Work)

在命令行输入

$ mkdir LearnGit

$ cd LearnGit

$ pwd

/e/Work/LearnGit

$ git init

Initialized empty Git repository in E:/Work/LearnGit/.git/

 

上述命令创建了一个名为LearnGit,并且通过git init命令把这个目录变成Git可以管理的仓库(当前目录下会多了一个.git的目录,是Git来跟踪管理版本库的,不要手动修改这个目录里面的文件,不然改乱了,就把Git仓库给破坏了)。

 

3. 添加(add)和提交(commit)文件

第一步,在LearnGit目录下新建文件GitTest.txt,输入内容“This is my first gittest.”

第二步,用命令git add告诉Git,把文件添加到仓库

$ git add GitTest.txt

 

第三步,用命令git commit告诉Git,把文件提交到仓库:

$ git commit -m "First GitTest"

[master (root-commit) e01e07a] First GitTest

 1 file changed, 1 insertion(+)

 create mode 100644 GitTest.txt

 

-m后面输入的是本次提交的说明,可以输入任意内容,当然最好是有意义的,这样你就能从历史记录里方便地找到改动记录。

 

4. 提交改动

修改GitTest.txt的内容,添加一行文字“This is my first modify.”

然后在命令行输入git status查看文件状态

$ git status

On branch master

Changes not staged for commit:

  (use "git add <file>..." to update what will be committed)

  (use "git restore <file>..." to discard changes in working directory)

        modified:   GitTest.txt

 

no changes added to commit (use "git add" and/or "git commit -a")

 

可以看到提示GitTest.txt已被修改,然后可以使用git diff查看差异

$ git diff

diff --git a/GitTest.txt b/GitTest.txt

index cea9dbd..cf91a5b 100644

--- a/GitTest.txt

+++ b/GitTest.txt

@@ -1 +1,2 @@

-This is my first gittest.

\ No newline at end of file

+This is my first gittest.

+This is my first modify.

\ No newline at end of file

 

然后重复提交操作,先add再commit

$ git add GitTest.txt

$ git commit -m "First Modify"

[master 15c7ddd] First Modify

 1 file changed, 2 insertions(+), 1 deletion(-)
