How to Clear All Git Commit History

Use git checkout –orphan new_branch to create an independent branch new_branch based on the current branch;

git checkout --orphan  main

Add all file changes to the scratch space

git add -A

Submit and add submission record

git commit -am "init"

Delete the branch you want to remove the commit record. This is master.

git branch -D master

Rename the current independent branch to master

 git branch -m master

Force push to remote branch

 git push -f origin master

If git push -f reports an error when pushing, it means that the permissions are insufficient. Or the main branch of Gitlab will be protected by default. You need to go to Project => Settings => Warehouse => Protected Branch to unprotect it.
