ok so i work as basically tier 2 tech support
am i in the wrong for being a little frustrated that my coworker (who is the same position as me) seems not to have basic CLI (like, windows command prompt even) skills?
@TheIronFox I guess maybe "tier 2" is not supposed rigidly defined, or maybe I don't have a very rigid understanding of what it means.
I reckon if you're in a large organisation with multiple tiers, then probably it's fine for tier 1 to be mostly surface-level triage, and tier 2 to have a deep understanding of the product, but that this doesn't necessarily mean they need any particular computer competency. But then, that also very much depends on the product, and what the tooling looks like, and so on.
I worked at a small place where tier 2 was just the developers themselves, and the relationship between tier 1 and tier 2 was more symbiotic - the folks who talked directly to customers and used the product all day had so much more understanding of how to use the product, so those of us in the dev department would ask the tier 1s almost as many questions as they would ask us, when there were cases that were more complicated than simply directing the customer in how to do something, or fixing a simple technical issue.

@TheIronFox So I guess in short, yes, you're in the wrong, assuming it's not necessary for your coworkers to know those things to do their job.
@TheIronFox tbh, depending on the product/customer base, i can forgive someone in L1 not having as good grasp on it which may be from lack of experience/usage, but at L2? i would found it very weird tbh 
nothing even that serious at all, just changing directories and running pre-made scripts for example
