in thread filter array based on 2 fields

More simply - and keeping the order:

@arr = ('c1,s1,d1','c2,s2,d2','c1,s1,d2','c1,s2,d3');
@arr = grep{ /(.+),/;
             !$seen{$1}++
           } @arr;
print join$/,@arr;

Prints:

c1,s1,d1
c2,s2,d2
c1,s2,d3

Hi it's an array like this (client,Status,Description client,Status,Description and so on) it's lines for a csv file I need to remove duplicates based on client and status as description can vary because of a timestamp Thanks Thorbjorn	[reply]
