海外TECH	DEV Community	Git Fundamentals: Concepts & Commands Simplified	https://dev.to/ruppysuppy/git-fundamentals-concepts-commands-simplified-2k4j	Git Fundamentals Concepts amp Commands SimplifiedGit is one of the most used tools in the tech industry as it efficiently solves the version control issue Without git even a simple project might end up looking like this Git helps to keep track of different versions of a single code base by tracking all changes With git even a complex project Material UI ends up looking condensed like this Even though git is a really useful tool everyone including me while starting has a lot of issues wrapping their heads around how it works This article aims at demystifying git for you Installing GitTo use git you will need to install it You can download and install git from git s website Make sure you add git to Path in case you are using it on Windows In Linux you can directly install it from the terminal using sudo apt get install gitAfter installation is complete to check if git was installed properly execute the command git version How Git Works Git works by storing a snapshot of the entire repository at any given point of time when you commit changes a commit can be considered to be an equivalent of a save So whenever you wish you can go back to any previous commits and make modifications Git Basics Initializing a RepositoryBefore you can use any functionalities of git you would require a repository To initialize a repository use git init Staging ChangesTo commit changes you need to specify the files whose changes you want to commit first This is done by staging the changes It is NOT required that you stage all files you modified you can stage only the files whose changes you want to commitTo stage changes use git add lt file path gt lt file path gt lt gt Or if you are lazy like me stage all changes using git add Committing ChangesFinally we come to committing changes To save the changes you have staged use git commit m lt small description of the change for ease of understanding gt You have successfully made your first commit LogsAfter several commits if you require to check out the commits you have made check out the logs using git log Resetting amp Reverting ChangesBut what if I make some mistakes in an old commit Fret not my friend git also has two solutions for that Reset RevertResetgit reset soft HEADLet s break down the command We are using git reset lt reset types gt HEAD lt number of commits to undo gt The most commonly used reset typess are soft uncommit and keep staged changes hard uncommit and delete changesRevertYou might also have noticed that every commit is associated with a hash You can also use the hash to undo a specific commit git revert acfdcdbbccaaabfOn breaking down the command we find git revert lt commit hash gt An additional commit is added on reverting modificationsWow We have made it quite far pat yourself on the back for the progress Now let s dive into a few more basic git features which are a bit harder to grasp BranchesIt is possible that you would be working on multiple different features at once Scoping all changes in one location is a perfect recipe for disaster for this case and since you are learning git you definitely would like to keep track of several copies of the same project Git has you covered There is a feature to create branches of the code to scope modifications like feature additions bug fixes etc to only one branch which may later be merged with other branches The former convention was to call the base branch master but recently the name has been changed to main You can change the name or the base branch as per your requirement though To create a new branch use git checkout b lt new branch name gt To switch to an existing branch use git checkout lt branch name gt MergeAfter completing work on a branch you may require updating a branch with the code from another branch For merging changes from another branch first move to the branch you want to update and use git merge lt update source branch name gt ConflictMerging branches may result in conflict if in both of the branches the same part of the same file was updated In such a case git doesn t know which change to keep and which to discard So git creates a conflict message for manual review The conflict message outlines where the conflict occurred as well as the current available in the branch and incoming changes merging from another branch After resolving the conflict you need to add a commit to save the resolved merge ConclusionIn this article we learned the basic concepts and commands of git and how to add it to a project Now you have this skill in your arsenal and would be able to use it in your projects to maximize your productivity Stay tuned for the article next week where we will be diving into how to use git for remote repositories hosted on sites like GitHub Thanks for readingWant to work together
