It's our first time to meet git

标签：

Recently,we had learned how to make version control during the development of software system.

Among all those tools,git is one of the most powerful one.And our team learned how to use it in a 

short time by learning from a blog written by LiaoXuefeng.

1.Install git

Thanks to our team member LinChun,his MacPro can directly use git beacause he had installed XCode.

2.Create a repository

　　　　　　　　　　　　create a directory

 　　　　　　　　　　　   init the repository and add a file to it

use "git add" to add files to temporary storage area 

　　"git commit" to add files to repository

　　　　　　　　　　　　　　　　the readme.txt

3."git status" and "git diff"

    "git status" is to see the current status of the repository,eg:

　 "git diff" is to check the difference ,eg:

4.update the version of the file

   first,make changes to readme.txt

  add it,commit it,check it

 repeat the process to get three different version of the text file,then we can

 use "git log" to see the logs of our versions

5.use command to roll back

　"git reset --hard Head(parameter to determine which version to roll back to)" eg:

    after rolling back,we can check the log to verify

   if we forget what we have done before,we can use "git reflog" to see the

   history of what we have done,eg:

6.delete files in git

rm just delete your file from the working directory

if you really want to delete the file from the repository,use "git rm"
