Question

what I’ve done:

git clone ssh://... ...
git commit
...
git commit

but there was a file (something secret 😉 which I should never push.
Normally, i would have done something like

git reset --soft HEAD^

to undo the last one, but it was too many commits ago

or:

git diff REV > /file.patch

to apply it on the top of remote/master, but I want to keep current commits

Answer 1

This works for me

git filter-branch --tree-filter 'rm -f passwords.txt' HEAD
