git five-minute tutorial

 Getting Started

  Before using Git, you need to create a repository. You can use an existing directory as the Git repository or create an empty directory

Use your current directory as the Git repository, we just need to initialize it

git init
Copy after login

Use the directory we specified as the Git repository

git init newrepo
Copy after login

From now on, we It will be assumed that you are in the Git repository root directory unless otherwise stated

 Add new files

 We have a repository, but nothing, you can use the add command to add files

git add filename
Copy after login

 You can use add... Continue to add task files

  Commit version

Now that we have added these files, we want them to actually be saved in the Git repository,

To do this, we commit them to the repository

git commit -m "Adding files"
Copy after login

If you don’t use -m the editor will appear Let you write your own annotation information

When we modify a lot of files and don’t want to add each one, and want commit to automatically submit local modifications, we can use the -a flag

git commit -a -m "Changed some files"
Copy after login

The -a option of the git commit command can only be All modified or deleted documents that have been managed by git are submitted to the repository.

 Please note that -a will not cause new files to be submitted, only modifications.

  Release version

We first clone a library from the server and upload it

git clone ssh://example.com/~/www/project.git
Copy after login

Now after we modify it, we can push it to the server

git push ssh://example.com/~/www/project.git
Copy after login

Retrieve the update

If you have already pushed as above, the following command indicates the current branch Automatically merge with the only tracking branch.

git pull
Copy after login

It has taken more than five minutes to update from a non-default location to the specified url

git pull http://git.example.com/project.git
Copy after login

?

 Deletion

 If you want to delete a file from the resource library, we use rm

git rm file
Copy after login

 Branch and merge

 The branch is completed locally and is fast. To create a new branch, we use the branch command.

git branch test
Copy after login

 The branch command does not take us into a branch, it just creates one. So we use the checkout command to change the branch.

git checkout test
Copy after login

 The first branch, or master branch, is called "master".

git checkout master
Copy after login

  While commits can be made on your branch, changes in the master branch will not be reflected. When you are done, or want to commit changes to the master branch, switch back to the master branch and use merge.

git checkout master
git merge test
Copy after login

  If you want to delete the branch, we use the -d flag

git branch -d test
Copy after login
