I assume you haven't been done much development in C, C++ or something similar then.

Because if you had, I don't know how you could not know that strace existed. Maybe you wouldn't know how to use it, but I don't see how you could be unaware of its existence if you are familiar at all with linux dev tools.

I've been tinkering on Linux as a hobby for about 2 years now and was made aware of strace a couple of months after starting to dig a bit deeper. You make me hopeful of my future employment.

I’m 100% telling the truth when I say I got a job as a Linux sys admin at a massive tech company on the basis of knowing a little bit of bash scripting. And this wasn’t even that long ago. Learn some devops stuff and you’re golden.
