I find it fascinating what new programmers prioritize. I’ve been developing on Unix and Unix like systems for 40 years and I’ve never needed a solution like this. But for some reason this appears to be a banger to some of you. Baffling but fascinating.
What is a "need"? I'm sure you can imagine why this could be useful. Is this life-changing? Does anyone need it? Probably not.
Your comment just makes you come off as some narrow-minded, graybeard elitist, and possibly even a little bit dumb, given how obvious it is why this could be useful. "New programmers", etc. Why not just .. not comment instead? Literally the easiest thing in the world for you to do since it requires you to do nothing.
If he thinks it's silly then he's welcome to say that. If someone with a lot of seniority wonders why you think you need a tool, maybe that's a hint that it isn't as obviously useful as you think. In this case, I get it, but a simple awk script can more or less do this work as well IF you think you need it.
