@Bartus11
Here comes again another one of your amazing one-liners ... could you please comment on the code Here are the parts which I think I understand: Correct me if I'm wrong please
$x="GAT" store name of query in $x
s/>.*// substitute > followed by anything on the first line with nothing, meaning ignore first line
s/\n//g remove new lines globally (but doesnt -l option do this automatically??)

The rest of it I didnt understand, please could you explain?

Thank you very much Smilie
