Many people think that Git is too confusing or a complicated version control system. This article is for some people who want to get started using Git quickly.
For most basic needs, this article covers 70% to 90% of usage
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
Use the directory we specified as the Git repository
git init newrepo
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
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"
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"
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
Now after we modify it, we can push it to the server
git push ssh://example.com/~/www/project.git
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
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
?
Deletion
If you want to delete a file from the resource library, we use rm
git rm file
Branch and merge
The branch is completed locally and is fast. To create a new branch, we use the branch command.
git branch test
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
The first branch, or master branch, is called "master".
git checkout master
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
If you want to delete the branch, we use the -d flag
git branch -d test
