IMO these kinds of poor man’s automation scripts are only useful to novice sysadmins but those are exactly the kind of people who shouldn’t be running scripts they piped from the internet for both the fact that it’s risky behaviour and the fact they don’t then get the experience doing this manually for themselves to move on from being novice.

That said, let’s not gate keep. If novices don’t want to gain experience actually doing sysadmin work and level up their abilities and just want stuff that will probably work but that they’ll not be able to fix easily if it doesn’t, at least it’s a starting point and when things break some of them will look deeper.
