Git: how to delete all commits except last one

Question

I load on git some project which contains some personal data. Now I changed all lines and commit it. Now I need to erase all commits except last one to prevent loosing personal data.

The best way is to merge all commits into one, which is answered by this question: http://stackoverflow.com/questions/7425725/how-to-merge-all-previous-commits-into-a-single-commit?rq=1 — Jon Cairns, Mar 25 '13 at 14:43

Given that your main branch is called master, and you want to remove all commits except the last one from your master:

git checkout --orphan tmp
git add . --all
git commit -m "Init."
git push origin tmp
On your remote git repo select tmp as main branch
git branch -D master
git push origin :master
git checkout -b master
git push origin master
On your remote git repo select master as main branch
git branch -D tmp
git push origin :tmp
