This feels like gatekeeping someone sharing something cool they've recently learned.

I personally lean more towards the "let's share cool little productivity tips and tricks with one another" instead of the "in order to share this you have to meet [entirely arbitrary line of novelty/cleverness/originality]."

But each to their own I suppose. I wonder how you learned about using xargs? Maybe a blog-post or article not dissimilar to this one?

I don't think there's anything wrong with sharing something cool, even if it's trivial to other people. The problem is framing a blog post with "ooh this was buried in the secret leaked CIA material".. and then the reader opens it to find out it's just xargs. It feels very clickbaity. Akin to "here's one simple trick to gain a treasure trove of information about all the secret processes running on your system!!" and it's just ps.

No I agree with you. This whole aura of "well IIIII knew this and YOUUUUU didnt" needs to die. I get that it's sometimes redundant and frustrating to encounter the same question a few times... but there's always new people learning in this world, and they deserve a chance to learn too.

Why do people constantly have to be looking for any way to justify their sense of superiority over others? Collaborative attitudes are so much better for all involved.
