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.

- benhoyt 3y agoBut 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. [1] https://www.austingroupbugs.net/view.php?id=1566 https://www.austingroupbugs.net/view.php?id=1566
- ryenus 3y agoAh good to know, thank you! Meanwhile I found it, it was the awk from Debian 10 that lacked `length(array)`, see the related nvm pr [1]. [1]: https://github.com/nvm-sh/nvm/pull/2917/ https://github.com/nvm-sh/nvm/pull/2917/
