Just to sum it up. Here (.) takes both columns as is a greedy quantifier and takes as much as possible and this is until the number (\d+) comes into play. `while (<DATA>) { m/(.*)\s+(\d+)/; $hash{$1} += $2; #$1 is the fruit $2 the number } for my $fruit (keys %hash) { print "$fruit $hash{$fruit}\n"; } __END__ Apple Grape 100 Ginger Fry 200 Apple Grape 80 Ginger Banana 800 Ginger Fry 150 Ginger Banana 45` [download]	[reply] [d/l]

Ah, but you don't really have three columns. You just have two columns, with the first column being "Apple Banana", etc.	[reply]

Ok..JavaFan. If i have the data "Apple banana 100" if i split on the basis of "\s+" it will split Apple and Banana...so how can i split in such a way that "Apple Banana " is the key and "100" is the value...give me some wisdom	[reply]
