版本控制
修改test.txt,随便加减点东西。
再运行 git status 命令查看结果(我测试用的是readme.txt)
$ 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是让我们时刻掌握仓库当前的状态,上面的命令告诉我们,readme.txt被修改过了,但还没有准备提交的修改。
虽然知道了readme.txt被修改了,但是具体修改了什么并不知道,通过git diff 命令来查看改了什么。
$ git diff diff --git a/readme.txt b/readme.txt index d8036c1..eb02596 100644 --- a/readme.txt +++ b/readme.txt @@ -1,2 +1,3 @@ Git is a version control system. -Git is free software. \ No newline at end of file +Git is free software. +Git is a distributed version control system \ No newline at end of file
确定修改的内容后,再提交到仓库中,提交修改和提交新文件是一样的两步,第一步git add
运行后和上次一样没有返回信息就是成功的。在运行git commit -m "add a line"
$ git commit -m "add a line" [master 4cf9a97] add a line 1 file changed, 2 insertions(+), 1 deletion(-)
再运行git status后回给我们当前没有需要提交的修改,而且工作目录是干净的。
$ git status On branch master nothing to commit, working tree clean
