    awk knows how to read files, no need for cat, and I suspect that the OP wants to be able to read the patterns from a file at runtime Commented Dec 22, 2016 at 13:09
  • args contains the arguments of a script. I'm not supposed to know what args contains. Commented Dec 22, 2016 at 13:10
  • @mike-m1342 is args inside a flat file or are they actual script arguments? If they are script arguments, you can just use the positional parameters in awk ($1, $2, etc). Hopefully that helps, but perhaps I still don't fully understand your goal. Commented Dec 22, 2016 at 13:16
  • args is a file. But I placed there the script arguments. How to use awk with all arguments at once? Commented Dec 22, 2016 at 13:22
