In this repo we have some accidentally included secret token that we have to completely purge from the history.

Command to run to clean the tree in a single commit (in bash):

for file in $(git ls-files | xargs grep -l "$secret"); do sed -i "s/$secret/${secret//?/x}/g" $file ; done ^ list offending files ^ replace the secret with all 'x's

Thus, the full commands might be:

export secret='Gh0sv0ORNBrn@ZEQnI3$yGhXju#DY#sgnmw8m6xe' git filter-branch --tree-filter 'for file in $(git ls-files | xargs grep -l "$secret"); do sed -i "s/$secret/${secret//?/x}/g" $file ; done' HEAD

Try it yourself!
