git revert will create a new commit that is the opposite of everything in the given commit.
We can revert the latest commit by using the head alias like this:

When you are done working with a branch and have merged it, you can delete it using the command below:
How to merge two branches in Git:
To merge the history of the branch you are currently in with the branch_name, you will need to use the command below:
How to show the commit log as a graph in Git:
We can use --graph to get the commit log to show as a graph. Also,
--oneline will limit commit messages to a single line.
How to show the commit log as a graph of all branches in Git:
Does the same as the command above, but for all branches.
How to abort a conflicting merge in Git:
If you want to throw a merge away and start over, you can run the following command:

How to check remote branches that Git is tracking:
This command shows the name of all remote branches that Git is tracking for the current repository:
How to fetch remote repo changes in Git:
This command will download the changes from a remote repo but will not perform a merge on your local branch (as git pull does that instead).
How to check the current commits log of a remote repo in Git
Commit after commit, Git builds up a log. You can find out the remote repository log by using this command:
How to merge a remote repo with your local repo in Git:
If the remote repository has changes you want to merge with your local, then this command will do that for you:

local branches. You can call git merge or git checkout to do the merge.
How to push a new branch to a remote repo in Git:
If you want to push a branch to a remote repository you can use the command below. Just remember to add -u to create the branch upstream:
How to remove a remote branch in Git:
If you no longer need a remote branch you can remove it using the command below:
How to use Git rebase:
You can transfer completed work from one branch to another using git rebase.
Git Rebase can get really messy if you don't do it properly. Before using this command I suggest that you re-read the official documentation here
How to run rebase interactively in Git:
You can run git rebase interactively using the -i flag.
It will open the editor and present a set of commands you can use.
How to force a push request in Git:
This command will force a push request. This is usually fine for pull request branches because nobody else should have cloned them.
But this isn't something that you want to do with public repos.
