Git clear all history

1. Go to the warehouse and pull a branch such as latest_branch

git checkout --orphan latest_branch

• --orphan create an orphan branch without any history

2. Add all files to the above branch and submit once

git add -A
git commit -am 'initial commit'

3. Delete the master branch

git branch -D master

4. Change the current branch to the master branch

git branch -m master

5. Push all local changes to the remote warehouse

git push -f origin master

• -f force push

6. Associate the local master to the remote master

git branch --set-upstream-to=origin/master

For gitee users, because gitee currently limits the size of a single warehouse to 1024 MB, after clearing the history, you need to go to the project homepage to do a repository GC
