How can I git push forward by using the “git push”?

In the context of DevOps, there are two methods present to git push fast forward. Here are the methods following:-

Using “git push –ff-only, if you haven’t made the changes from the remote yet, then try this:-

Git fetch
Git merge-base HEAD origin/branch_name
Git push –ff-only origin HEAD:branch_name
If you have fetched the changes then use:-
“git push –ff-only origin HEAD:branch_name”
Using “git push – force-with-lease
“git push –force-with-lease origin HEAD:branch_name

If you do not know about DevOps, –force-with-lease is safer than –force. It is so because, if you use force with the lease, it will prevent accidentally overwriting their changes.
