Awk is really great, for those knowing nvm [1], I used awk to make `nvm ls-remote` run more than 10 times faster [2] by replacing the related shell script with around 60 lines of awk script [3], and I was quite happy with the improvement.
It's not really a one-liner, neither something big, but one can take that as an example regarding that awk is really not just for one-liners.
Meanwhile having `--csv` support is really nice. I'd also like to see things like a builtin `length` function to be standard.
But length() is standard POSIX, no? Even length(array) has been approved by POSIX [1] but not yet included in the spec (they're very slow to update the spec for some reason). Both forms have been supported in onetrueawk, Gawk, mawk, and Busybox awk for a long time.
