Recently though, I've been assigned a guy to help me with one of my tasks, managing the build pipeline. This requires a wide range of knowledge about unix and scripting (Bash, Perl AND Python. Yup. On top of Makefiles, of course).
The guy doesn't know how to use a command-line.
I'm surprised to find myself to be very unhelpful and curt with this guy. He's the unlucky recipient of my resentment at the amount of effort I will have to put in before he can actually become remotely helpful. Of course, it doesn't help that he's in far off timezone where I'd have to stay up late to help him, and that I have trouble getting direct answers from him about his knowledge level. The communication and experience gap is too large.
Anyhow, this is just my two cents relating an experience to show how a seemingly normal and friendly human being can revert to angry "RTFM"s.
