I remember the days when I was working in a data company and one of the product check tools was a 2000 line GNU awk script with some korn shell in the mix. It was both scary and awesome at the same time..
One thing I always wanted gawk to do is to manipulate ARGV and add the file-system URL’s it does networking with. I’ve tried it a few times, but it never managed to properly work.
But it’s great to see that there is still active development on the project.
