GitHub - removing old files

# --------------------------------------------------------------
see instructions here to remove file from history:

https://docs.github.com/en/github/authenticating-to-github/removing-sensitive-data-from-a-repository

# --------------------------------------------------------------
# I can try this to delete all history from terminal
# --------------------------------------------------------------

# ---------------------------
# commit all the changes, make sure you are up-to-date
gist
gg

# ---------------------------
# make a copy of the repository (just in case)
cd ~/Documents/GitHub
rsync -a myrepo ./OLD/

# ---------------------------
# go into repository and run commands
cd myrepo

git checkout --orphan latest_branch
    # Switched to a new branch 'latest_branch'
git add -A
git commit -am “init”                     # Committing the changes
git branch -D master                      # Deleting master branch
git branch -m master                      # renaming branch as master
git push -f --set-upstream origin master  # pushes to master branch
git gc --aggressive --prune=all # remove the old files

# --------------------------------------------------------------
# The git reflog expire command prunes all entries older than the current time 
# while git gc removes unreachable files and recompresses the repository.
git reflog expire --expire=now --all && git gc --prune=now --aggressive

# --------------------------------------------------------------
Create an archive of git repository
https://riptutorial.com/git/example/9513/create-an-archive-of-git-repository

Several ways of achieving this:

git archive --format tar HEAD | cat > archive-HEAD.tar
git archive --format tar HEAD | gzip > archive-HEAD.tar.gz
git archive --format tar.gz HEAD > archive-HEAD.tar.gz
git archive --format zip HEAD > archive-HEAD.zip
git archive --output=archive-HEAD.tar.gz HEAD
