Question

I backed up my database to GIT just so I could get the db at my home computer.

I don’t want this file to be versioned, it was just a 1 time thing really.

Can I delete it for good so GIT doesn’t keep track of it going forward or historically?

Answer 1

I always find Guides: Completely remove a file from all revisions feed helpful.

To remove the file called Rakefile:

git filter-branch --force --index-filter \
  'git rm --cached --ignore-unmatch Rakefile' \
  --prune-empty --tag-name-filter cat -- --all

This command will run the entire history of every branch and tag, changing any commit
that involved the file Rakefile, and any commits afterwards. Commits
that are empty afterwards (because they only changed the Rakefile) are
removed entirely.
