Cant get awk 1liner to remove duplicate lines from Delimited file, get "event not found" error..help

Hi,

I am on a Solaris8 machine

If someone can help me with adjusting this awk 1 liner (turning it into a real awkscript) to get by this "event not found error"

...or

Present Perl solution code that works for Perl5.8 in the csh shell ...that would be great.
******************

Here is the comma delimited InputFile i have (File1.dat):

It has (7 records each with 3 fields)

I want to define a duplicate record as any record where Field1 & Field2 values repeat across 2 or more records so that in by input file below...I have 3 duplicate records. Then I want to only keep the 1st occurrence of this duplicate record.

kk,12,a
aa,11,n --> duplicate
ee,13,b
aa,11,f --> duplicate
bb,17,k
pp,12,t
aa,11,w --> duplicate

What I want my awk script or perlscript to do is produce the following output (that is reduce the file from the 7records to 5records) , in essence keeping the 1st duplicate line, record only (again duplicate is defined as Field1 & Field2 having the same value across the records)

Desired Output File is here (5records, it kept only the 1st duplicate):

kk,12,a
aa,11,n
ee,13,b
bb,17,k
pp,12,t

I tried the following awk 1-liner at the csh prompt

awk '!x[$1,$2]++' FS="," File1.dat

but got the error message "Event not found"

***********

If someone knows how i can correct the above awk 1liner or how to make an alternative multi-line awk or perl script to do this ..that okay with me also. Just let me know where in your code it references

a) the fact that the files are comma delmited
b) Field1 & Field 2 as the fields by which to classify a record as a duplicate

Thanks in advance (this has stumped me for hours ..)

aclsort

aclsort(3C)															       aclsort(3C)

NAME

       aclsort() - sort an Access Control List (JFS File Systems only)

SYNOPSIS

DESCRIPTION

       The routine sorts JFS Access Control List (ACL) entries into the correct order to be accepted by the acl(2) system call.

       points  to a buffer containing ACL entries; if non-zero, indicates that the permissions should be recalculated; and specifies the number of
       ACL entries in the buffer.

       sorts the contents of the ACL buffer as follows:

	      Entries will be in order and

	      Entries of type and will be sorted in increasing order by numeric ID.

       The call will succeed if all of the following are true:

	      There is exactly one entry each of type and

	      There is at most one entry each of type and

	      Entries of type or may not contain duplicate entries.  A duplicate entry is one of the same type containing  the	same  numeric  id,
	      irrespective of permission bits.

	      If the argument is zero and there are no entries of type and no entries of type the permissions of the and entries must be the same.

	      If  there  are  no entries of type and no entries of type and the entry is specified, then the entry must also be specified, and the
	      permissions of the and entries must be the same.

RETURN VALUE

       Upon successful completion, the return value is 0.  If there are duplicate entries, the return value is the position of the first duplicate
       entry.  If there is more than one entry of type or they are treated as duplicate entries, and the return value is the position of the first
       duplicate entry.  For all other errors, the return value is -1.

NOTICES

       The buffer is sorted by type and ID before checking for any failures.  Therefore the buffer is always sorted, even if there is a failure.

       The position of a duplicate entry returned on failure is not the byte offset of the duplicate entry from its base; rather it refers to  the
       entry number of the duplicate entry within the sorted buffer.

       Checks  will  be performed in order of entry type.  If there are multiple failures, the failure returned will be the first encountered, for
       example, if the ACL buffer contains a duplicate entry and does not contain an entry, the return value will be the first duplicate entry.

       ACLs do not have to be sorted with prior to passing them to acl(2).

DEPENDENCIES

       is supported only on JFS file systems on the standard HP-UX operating system.
