If the user's home directory is owned 96by the user, 97.Nm 98asks whether you wish to remove the user's home directory and everything 99below. 100.Pp 101As 102.Nm 103operates, it informs the user regarding the current activity. If any 104errors occur, they are posted to standard error and, if it is possible for 105.Nm 106to continue, it will. 107.Pp 108Available options: 109.Pp 110.Bl -tag -width username 111.It Fl y 112Affirm - any question that would be asked is answered implicitly in 113the affirmative (i.e., yes).
