hi
This is probably a well know thing but somehow I missed it. Let say I have the following oneliner: 
perl -lne '/^([^\t]*)\t/; $hash{$1}++}{print $_ foreach(keys %hash)' i
+nfile.txt

My question is : What would be the simplest way to apply this one-liner to each file in my directory: ls dir | for each file execute: perl -lne '/^([^\t]*)\t/; $hash{$1}++}{print $_ foreach(keys %hash)' thnx
