提交修改

查看修改：

1.先對某個文件做修改

2.運行git status命令看看結果：

$ git status
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   readme.txt

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

git status命令可以讓我們時刻掌握倉庫當前的狀態，上面的命令輸出告訴我們，readme.txt被修改過了，但還沒有準備提交的修改。

3.用git diff這個命令查看被修改的地方：

$ git diff readme.txt 
diff --git a/readme.txt b/readme.txt
index 46d49bf..9247db6 100644
--- a/readme.txt
+++ b/readme.txt
@@ -1,2 +1,2 @@
-Git is a version control system.
+Git is a distributed version control system.
 Git is free software.

git diff顧名思義就是查看difference

 

提交修改：

1.先是git add：

$ git add readme.txt

2。提交

$ git commit -m "add distributed"
[master e475afc] add distributed
 1 file changed, 1 insertion(+), 1 deletion(-)

3.git status命令看看倉庫的當前狀態：

$ git status
On branch master
nothing to commit, working tree clean
