rindex - right-to-left substring search. rmdir - remove a directory. s/// - replace a pattern with a string. say - output a list to a filehandle, appending a newline. scalar - force a scalar context. seek - reposition file pointer for random-access I/O. seekdir - reposition directory pointer. select - reset default output or do I/O multiplexing I think rindex is the way to go.
