To undo the most recent local commits in Git, you can use the command git reset. The exact command will depend on how you want to undo the commits.
- To completely remove the most recent commit, use the command
git reset --hard HEAD~1. This will reset the branch to the previous commit and all changes made in the most recent commit will be lost. - To undo the commit and keep the changes, use the command
git resetHEAD~. This will un-commit the changes but keep the changes staged in the index, ready to be recommitted. - To undo the commit and unstage the changes, use the command
git reset --mixed HEAD~. This will un-commit the changes and remove them from the index, so they will not be recommitted. The changes will still exist in the working tree and can be recommitted using a different commit message.
It’s important to note that these commands will only undo local commits and will not affect any commits that have already been pushed to a remote repository. If you have already pushed the commits, you should use caution when resetting your branch, as it may cause conflicts with other contributors.
How to delete a Git branch locally and remotely?
To delete a Git branch both locally and remotely, you can use the following steps:
Delete the local branch: Use the command git branch -d <branch_name>. Replace <branch_name> with the name of the branch you want to delete.
Push the deletion to the remote repository: Use the command git push origin --delete <branch_name>. Replace <branch_name> with the name of the branch you just deleted locally.
Note: If you have not yet merged the branch you want to delete into the branch you are currently on, you will need to use the command git branch -D <branch_name> instead of git branch -d <branch_name> to force the deletion of the branch.
It’s always a good idea to verify that the branch has been deleted successfully by using the command git branch to see a list of all local branches and git branch -r to see a list of all remote branches.
Difference between ‘git pull’ and ‘git fetch’?
The main difference between git pull and git fetch is that git pull automatically merges the changes from a remote branch into your current branch, while git fetch only downloads the changes from the remote repository and stores them in your local repository, but does not merge them.
git pull is a convenient way to update your local repository with changes from a remote repository. It combines the functionality of git fetch and git merge into one command. When you run git pull, it downloads the changes from the remote repository, and then immediately merges the changes into your current branch.
git fetch, on the other hand, only downloads the changes from the remote repository and stores them in your local repository. It does not merge the changes into your current branch. To merge the changes, you will need to run a separate git merge command.
The advantage of using git fetch is that it allows you to inspect the changes before merging them into your current branch. This can be useful when you are working with a team, and you want to review changes made by other team members before merging them into your code.
In summary, git pull is a quick and convenient way to update your local repository, while git fetch is a more manual way to update your repository that gives you more control over the process.
