You can demonstrate how to view a list of available branches by executing the git branch command and switch to a specified branch. The git branch and git checkout commands can be integrated. ![]() We can perform many operations by git checkout command like the switch to a specific branch, create a new branch, checkout a remote branch, and more. It checks the branches and updates the files in the working directory to match the version already available in that branch, and it forwards the updates to Git to save all new commit in that branch. Sometimes this command can be dangerous because there is no undo option available on this command. The git checkout command operates upon three different entities which are files, commits, and branches. Be careful with your staged files and commits when switching between branches. The git checkout command is used to switch between branches in a repository. Prepare to work on top of , by detaching HEAD at it (see 'DETACHED HEAD' section), and updating the index and the files in the working tree. If you specify "HEAD" as the revision, you will restore the last committed version of the file, effectively undoing any local changes that you current have in that file: $ git checkout HEAD index.In Git, the term checkout is used for the act of switching between different versions of a target entity. git checkout-detach git checkout -detach . Creates the branch , start it at if it already exists, then reset it to .If, in one go, you also want to create a new local branch, you can use the "-b" parameter: $ git checkout -b new-branchīy using the "-track" parameter, you can use a remote branch as the basis for a new local branch this will also set up a "tracking relationship" between the two: $ git checkout -b new-branch -track origin/developĪnother use case for "checkout" is when you want to restore an old revision of a file: $ git checkout 8a7b201 index.html This will make the given branch the new HEAD branch. In its simplest (and most common) form, only the name of an existing local branch is specified: $ git checkout other-branch If you want to restore a specific earlier revision you can provide that revision's SHA-1 hash. git init a new git repo in an existing folder git clone /project/scv/dirname. By providing HEAD as the revision, you can restore the last committed version of a file - effectively undoing any local changes that happened since then. Restores a historic revision of a given file. when unpushed commits in the local branch or unpulled commits in the remote exist). This allows you to more easily see when the two aren't in sync (i.e. This way, the new local branch has a tracking relationship with its remote counterpart. Then the git reset resets the master branch to what you. This can be used as a shortcut instead of the following two commands:Ĭreates a new local branch - and sets up an "upstream" configuration. Well first of all git fetch downloads the latest from remote without trying to merge or rebase anything. ![]() b Ĭreates a new local branch and directly switches to it. By specifying the name of a local branch, you will switch to this branch and make it the current "HEAD" branch. The name of a local branch that you want to switch to. ![]() ![]() Thereby, you can reset single files to earlier revisions - while keeping the rest of the project untouched. The most common use case for "checkout" is when you want to switch to a different branch, making it the new HEAD branch.Īnother use case for "checkout" is when you want to restore a historic version of a specific file. Local modifications to the files in the working tree are kept, so that they can be committed to the .The index may contain unmerged entries because of a previous failed merge. The "checkout" command can switch the currently active branch - but it can also be used to restore files. git checkout with or -patch is used to restore modified or deleted paths to their original contents from the index or replace paths with the contents from a named (most often a commit-ish).
