Re: How do i extract 3 variables from each line in a file, and print them to a new file

you'll probably see a bunch of different ways, including split .. here's one pure regex way:

open OUTFILE, ">out.txt";
open INFILE, "in.txt";
while(<INFILE>){
  next unless /(\d{1,3})ms:(\d{1,3})ms:(\d{1,3})ms/;
  print OUTFILE join(",", ($1, $2, $3) ), "\n";
}
close OUTFILE;
close INFILE;

That one is an almost complete solution... Mine is shorter; this one should give the closest match... Add "$" at the end of your regex and it will be perfect... -------------------------------- An idea is not responsible for the people who believe in it...	[reply]

your solution didn't work ... Yeah, i guess i could anchor to the end (especially since OP said 'last 3 numbers' but might be able to assume that the ":ms" strings in there will be restrictive enought to get the right one.. i guess to go strictly by 'last 3 numbers' the `(\d+)\D+` solution above is better (though in that one i would make the last `\D+` a `\D*`)..

I realized that and updated one works :) And in the solution above, last \D+ can stay \D+ instead of \D* because "ms" is two letters, and \D+ gets at least one so it also matches two but not matches zero occurrences (as opposed to \D, which does) -------------------------------- An idea is not responsible for the people who believe in it...*	[reply]
