What is the Git command to delete a local branch named "experiment" without a warning?

git branch -n is not a valid Git flag for branch deletion; -n has no recognized meaning in the git branch command.

git branch -rm is not a valid Git command; Git uses -d or -D for branch deletion, not -rm.

git branch -f is the force-reset flag used to move an existing branch pointer to a specific commit, not to delete a branch.

git branch -D is the force-delete shorthand equivalent to --delete --force, which removes the branch unconditionally without checking whether its changes have been merged into another branch, so no safety warning is issued.
