So the dash in `-czf` if optional? Which reminds me: why does ps have two sets of options again?

- atsaloli 5y agoDon't laugh, it's actually three sets of options now: - UNIX options, which may be grouped and must be preceded by a dash. - BSD options, which may be grouped and must not be used with a dash. - GNU long options, which are preceded by two dashes.
