Weather or not your overseeing people you are overseeing projects and larger scale strategic strategy, which makes you a manager.
You don't have the luxury anymore of being able to do things yourself. Context switching from strategic to tactical mode and back has a huge cost. Humans suck at multitasking. That's the reason that in most human endeavors over the millennia we've settled on the idea that organizations work most effectively when you have a few people overseeing the larger scale picture and many people managing the day to day tactical situation and reporting the information that the leaders need in order to make decisions up.
You can no more be successful if you're in systems typing ps to discover what's going on as a general can be if they had to write every field report by hand. At best you'll burn yourself out and then everyone will be in trouble.
Instead my advice would be to take this as a coaching opportunity. "Hey, I'd like to take a peek at this config file. Mind bringing it up for me? Ah, see, that's where the problem is, you how that quotation mark is missing? The next line is being included int he string. Thanks, I'll raise a change to fix that." You've just taught someone something. Next time they will remember to check their string terminators. It's a win-win.
And I know this because I was in EXACTLY the same spot and mindset as you about 10 years ago. It's time to shift your mental viewpoint. It's not easy, but the fact that you were given this responsible suggests your fellow leaders believe you're up for it.
