git tag -d [tag]
git push origin :[tag]
If your tag has the same name as one of your branches;
git tag -d [tag]
git push origin :refs/tags/[tag]
git branch
git branch branchname <sha1-of-commit>
git push origin BRANCH_NAME
git clone -b <branch> <remote_repo>
git branch -m old_branch new_branch # Rename the branch locally
git branch -m new_branch # Rename the currently checked out branch
git push origin new_branch
# Then go to GitHub UI settings/options, if the old branch was 'master', change 'Default Branch' to another branch that is not 'master'. Then
git push origin :old_branch # Delete the old branch
# Revert changes to modified files.
git reset --hard
# Remove all untracked files and directories. (`-f` is `force`, `-d` is `remove directories`)
git clean -fd
Firstly, find out the comit that you want to revert back to.
git log
For example, commit 7f6d03 was before the 2 wrongful commits. Force push that commit as the new master:
git push origin +7f6d03:master
The + is interpreted as forced push. You can also use git reset to undo things. Then force push.
git reset 7f6d03 --hard
git push origin -f
Setting your branch to exactly match the remote branch can be done in two steps:
git fetch origin
git reset --hard origin/master
If you want to save your current branch’s state before doing this (just in case), you can do:
git commit -a -m "Saving my work, just in case"
git branch my-saved-work
