git patch automatic code replacement in repository

git show commitID -- folder/ >> 001commitID.patch

cd to fresh git repo without changes and

git apply 001commitID.patch

GitHub hide and change mail in project repository files

git config --global user.name "USER"

git config --global user.email "123456789+USER@users.noreply.github.com"

git config --global --list

git config --local --list

Make sure working tree is clean:

git status

git add .

git commit -m "commit comment"

git filter-branch --env-filter '

export GIT_AUTHOR_EMAIL="123456789+USER@users.noreply.github.com"

export GIT_COMMITTER_EMAIL="123456789+USER@users.noreply.github.com"

' -- --all

rm -rf .git/refs/original

git reflog expire --expire=now --all

git gc --prune=now --aggressive

git log --reverse --format="%h %an <%ae>"

If you see:

yourname@users.noreply.github.com

git filter-branch --env-filter '

export GIT_AUTHOR_EMAIL="1123456789+USER@users.noreply.github.com"

export GIT_COMMITTER_EMAIL="123456789+USER@users.noreply.github.com"

' -- --all

git log

⚠️ This replaces the online repo history:

git push --force --all

git push --force --tags

git log

git log --all --author="yourname"

git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d

git stash clear

git reflog expire --expire=now --all

git gc --prune=now --aggressive

What others must do (if anyone cloned). They must reclone, or:

git fetch --all

git reset --hard origin/main

git log --all --author="yourname"
