[sudo-users] sudo command syntax changed itself.

[nhoj odarroc]

MAC OS X 10.5.8. I have been using sudo -r -f to delete stubborn files but today when I tried to delete file that was hanging my system, it wouldn't work. I did man sudo and saw that the command no longer has the options -r -f. What happened? It now uses -K to kill a file but every time I enter the command sudo -K (filename) it ignores the command and show syntax for proper use. What is the proper format to use to kill files in the trash when the 501 file can't be found?
