git commits 大合併

# Reset the current branch to the commit just before the last 12:
git reset --hard HEAD~12

# HEAD@{1} is where the branch was just before the previous command.
# This command sets the state of the index to be as it would just
# after a merge from that commit:
git merge --squash HEAD@{1}

# Commit those squashed changes.  The commit message will be helpfully
# prepopulated with the commit messages of all the squashed commits:
git commit

強制覆蓋 github 版本 (需注意這步將無法還原)

git push -f origin

What happens to the forks when deleting the original repository?

It depends whether the original and the fork are public or private, according to GitHub’s documentation:

• Deleting a private repository will delete all of its forks.
• Deleting a public repository will not delete its forks.

More detail on this page:

Get github access token

Username for 'https://github.com': XXXXXXXXXXXX
Password for 'https://XXXXXXXXXXXX@github.com':
remote: Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.
remote: Please see https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/ for more information.
fatal: Authentication failed for 'https://github.com/xxxxxxxx/xxxxxx.git/'

現在在使用 git clone 如果遇到要登入帳密的問題 tool 會告知要使用token 當密碼

打開github -> Settings -> Developer settings -> Personal access token –> Generate new token -> repo 勾起來-> save

Deleting a private repository

When you delete a private repository, all of its private forks are also deleted.

Deleting a public repository

When you delete a public repository, one of the existing public forks is chosen to be the new parent repository. All other repositories are forked off of this new parent and subsequent pull requests go to this new parent.
