I think you actually confirmed my point when you said 'no sysadmin has time or interest'. I didn't say that no one uses shell anymore. I said that there was no practical justification for doing so. Lots of people still use it and don't have any interest in finding a better solution. These people are choosing, for their own reasons, to double down on an obsolete skillset. Good for them, I suppose, but I don't think that demand for their niche is going to be around for very long.
I also pointed out that sysadmins who know what they're doing use awk. Based on your mentioning awk it seems like you agree with this.
