Removing files from git history - bad revision error

Solved... I took out the space after the backslash which I'd been putting in before the --prune-empty part, and it works as expected now! No idea why it works though....

Git should run from either cmd.exe or bash.

The problem is the use of ' in your command. Windows only uses ". The command you are looking for is:

git filter-branch --force --index-filter \
"git rm --cached --ignore-unmatch *.csv" \
--prune-empty --tag-name-filter cat -- --all
