git diff can be used to compare commits, branches, files, and more. Once a developer created a pull request, the rest of the team members can review the code, and then merges the new changes into the master branch.ģ. Pull request is a feature that makes it easier for developers to collaborate. Open a “pull request” (aka “PR”) and request to merge the changes to the main branch After setting an upstream, next time when you push some changes to the remote server, you can simply type git push.Ĩ. This command will set the branch as the default branch, which allows you to push the changes without specifying the branch you are pushing into. You can set an upstream by adding -u, git push -u origin. The git set-upstream allows you to set the default remote branch for your current local branch. Git commit -m “message about the changes you've made” ▶️ git add -ignore-removal //Stage all modified and deleted files ▶️ git add -u (note: -u is shorthand for -update) The previous commands will also remove a file from your repository if it no longer exists in the project. Add a file or make some changes to your file to your local repo then put it into the staging area when you are ready to save the changes //Add one file ▶️ git add //Add all the new/modified/deleted files to the staging area ▶️ git add -A (note: -A is shorthand for -all) //Stages files in the current directory and not any subdirectories, whereas git add -A will stage files in subdirectories as well. Using this command, the local changes you made will be rebased on top of the remote changes, instead of being merged with the remote changes.ĥ. Git rebaseallows us to apply our changes on top of the remote master branch, which gives us a cleaner history. So git pull is similar to git fetch+ git mergeat the same time. the local changes are merged into the remote changes. Generally, this is done by git merge, i.e. git pullfetches the latest changes of the current branch from a remote and applies those changes to your local copy of the branch. While git pulland git rebaseare closely connected, they are not interchangeable. Resolving conflicts during this step can help keep your feature branch history clean and have an easier time with merging at the end. We often see conflicts happen in this step. To keep your feature branch fresh and up to date with the latest changes in the master branch, use rebase ▶️ git pull ▶️ git pull -rebase origin master To separate the functionalities, the GIT community introduced this git switch command.Ĥ. git checkout can be used to switch branches and restore the working tree files, and it can be confusing. Git switchis not a new feature but an additional command to the overloaded git checkoutcommand. Create a “branch” (optional but recommended) //create a new branch and switch to it at the same time ▶️ git checkout -b ▶️ git switch -c //simply switch to an existing branch ▶️ git checkout ▶️ git switch Use the code drop down to find the HTTPS/SSH URL. Add the remote repository / Copy (or clone) the repository to your local machine //add the remote repository ▶️ git remote add origin // clone the repository ▶️ git clone If you accidentally type git init in the wrong place, you can undo it by typing rm -rf. Make sure you are in a root folder of your project when you type git init, otherwise, git will track all the files on your computer and slow everything down. Create a “repository” (project) with a git hosting tool (like Github).In this article, I’ll share some common Git Commands along with some comparisons and their use cases. Besides Github, there are many other services such as Bitbucket, GitLab, Codebase, Launchpad, etc. Github is a cloud-based hosting service that hosts and manages Git repositories, which expands upon Git’s basic functionality. It’s important to note that Git and Github are not the same. You may have heard of Github before and may wonder what the difference is between Git and Github. This allows us to look back at all the changes we’ve made over time, which helps us to see when and what we did, as well as convert back to a previous version of the code if needed. So what is version control? Version control is a way that we as a programmer track our code changes and a way to collaborate with other programmers. Most programmers and data scientists interact with git on a daily basis. Git is a free and open-source version control system.
