CentOS Linux delete file begins with a dash or hyphen

If the name of a file or directory or folder starts with a dash (- or hyphen --), use the following syntax:
rm -- -filename
rm -- --filename
rm -rf --dirname
rm ./-file
rm -rf ./--dirname

Do not run ‘rm -rf /‘ command as an administrator/root or normal CentOS Linux user

rm -rf (variously, rm -rf /, rm -rf *, and others) is frequently used in jokes and anecdotes about CentOS Linux disasters. The rm -rf / variant of the command, if run by an administrator, would cause the contents of every writable mounted filesystem on the computer to be deleted. Do not try these commands on CentOS Linux:
rm -rf /
rm -rf *
