It started to deviate from my original question, and before it goes too far, I accept the answer by RudiC
Quote:
Can I say there is no regexp for this case in awk, similar to your perl script ?
Code:
perl -e '{print "-\t"x11, "-\n"}'

You seem to be caught in an error: regexes exist for searching/matching purposes ONLY. You can't print them. For printing a repetitive pattern, you need to type it as is, use a loop, or fall back to tricks as posted before.
Thanks again for all your replies.
