Push command is used to upload local repository content to a remote repository. When you have made changes to your local repository (such as new commits) and want to share those changes with others or save them on a remote server, you use git push.

Push a commit

To push the current staged changes you can use:

git push

To edit the last commit you can use:

git commit --amend

And you have to use force push incase you need to push the edited commit to the remote repo.

git push --force

Delete Pushed commit

To delete the last commit that has been pushed to the remote repo

git reset --hard HEAD~1
git push origin --force HEAD

If you want to delete the last five commits

git reset --hard HEAD~5
git push origin --force HEAD

If you want to remove a specific commit by it commit id

git reset --hard <sha1-commit-id>
git push --forced HEAD

Where < sha1-commit-d > is the commit id, that you can git by git log

Pull commit

To update your current repo with the latest update from the remote repo, you can use:

git pull

and if it was already forced push, you can pull it by

git pull --rebase

Push with specific ssh key by

git config core.sshCommand "ssh -i ~/.ssh/your_specific_key"

Edit the last commit

Edit the last files

git commit --amend

Edit only the commit message without files change

git commit --amend --no-edit

Edit the Author

git commit --amend --no-edit --author "Amr Tarek <amr.tarek@example.com>"

You have to force push after using --amend by using git push --force
