Which Git command do you use to consolidate all changes from one branch with another branch using a single commit? Please choose the correct answer.
Correct Answer: C
The Git command that you use to consolidate all changes from one branch with another branch using a single commit is merge. The merge command is used to integrate changes from another branch into the current branch. The target of this integration (i.e. the branch that receives changes) is always the currently checked out HEAD branch. The merge command can create a merge commit, which is a special commit that has two or more parent commits and records the result of the merge. Alternatively, the merge command can also perform a fast-forward merge, which is a simple update of the HEAD pointer without creating a new commit, if the current branch is an ancestor of the other branch.
For example, suppose you have two branches, master and feature, and you want to consolidate all changes from feature into master using a single commit. You can use the following commands:
git checkout master # switch to the master branch git merge feature # merge the feature branch into the master branch This will create a merge commit on the master branch that has two parents: the previous tip of the master branch and the tip of the feature branch. The merge commit will contain all the changes from the feature branch as well as the changes from the master branch.
The following Git commands are not used to consolidate all changes from one branch with another branch using a single commit, but for other purposes:
* Commit: The commit command is used to create a new commit on the current branch that records the changes made in the working tree and the index. The commit command does not integrate changes from another branch, but only from the local repository.
* Rebase: The rebase command is used to reapply a series of commits from one branch on top of another branch. The rebase command does not create a single commit, but rather modifies the history of the current branch by rewriting the commits and changing their parent commits. The rebase command can be used to achieve a linear history, but it can also cause conflicts and inconsistencies if used on public branches.
* Push: The push command is used to transfer commits from the local repository to a remote repository.
The push command does not integrate changes from another branch, but only from the local repository to the remote repository. The push command can also update the remote branch pointers to reflect the
* transferred commits.
