Whats the alternative to sqlldr because I want to add (update) not insert..

Question

mornin gurus..
As title asks, Ive just sussed that SQLLDR just inserts into an empty table, but I need to update AND Insert..
I'll be running the code/command from a UNIX script. But just to get me started - how do I do this..?
I'll be calling a file, then asking each record in the data file specified to either update or insert into an ORACLE table..
If you need any more info just let me know..
cheers

ahh! Append -great stuff thanks..
Don't suppose I could be cheeky as to ask why its now failing though ()Its been soo long since Ive used ctl files....
error message I'm getting is..
Record 1: Rejected - Error on table SU_EMP_AUDIT.
ORA-00001: unique constraint (APPS.SYS_C00555887) violated
Record 2: Rejected - Error on table SU_EMP_AUDIT.
ORA-00001: unique constraint (APPS.SYS_C00555887) violated..I'm guesing its something I need to add to the ctl file that allos the datafile to have either '0's or null values..
data file looks like..
0022150,Young,Valerie,Valerie,0,0,20100913,,FAC202,Domestic Assistant,27.03,FACI,FACR,SUPP,T4,0,0,0,0,0,0,0,0,,Mrs,PT,PT,New
