• Specify the name of the file you want to clean with FILENAME="".
• With the git filter-branch command, we can clean all traces of a specific file in Git history.
• The force parameter is used to prevent errors when the filter branch already exists.
• The index-filter parameter specifies the command run for each commit.
• We remove all versions of the specified file with the git rm --cached --ignore-unmatch $FILENAME command.
• The prune-empty parameter removes empty commits that do not include file changes.
• The tag-name-filter cat -- --all parameter performs operations on all branches and tags.
• We forcefully push the changes to the remote repository with the git push origin --force --all and git push origin --force --tags commands.
• We delete the original references with the git for-each-ref --format='delete %(refname)' refs/original | git update-ref --stdin command.
• We clean the git history with the git reflog expire --expire=now --all and git gc --prune=now commands.
