Have you had sysadmin colleagues that knew NO scripting whatsoever?

Yes. It confounds me at times. Former workplace had a really bad contractor who refused to write shell scripts for various insane reasons: security listed as the primary one. I suspect it was a mixture of incompetence and job security which tells you all you need to know about my opinion of the man. Sadly, the company considered him an "elder experienced person" and so they always took his questionable advice. Also hated DNS, did everything by hosts files. I checked his .bash\_history and got a gist of what he was doing, and 90% of it was shit simple stuff he'd charge hours for, like "Log into SQL database, pull out metrics (like DB health stats), write metrics to file, mail file to emailed report group." Like 4-5 lines of bash script that might take a normal person less than a minute to cut and paste commands (and given the formatting, I think that's what he was doing), and a bash script a matter of seconds. I felt I could do his entire daily job in less than an hour, and automate it so I didn't have to do it again. I have run into a lot of junior admins who are also quite bad at scripting. Lot of paper tigers are like this, since they tell you commands, but don't really tell you about scripting at all. There's also been a wave of people who think "if I write a script, they will know I am doing simple work, and I will automate myself out of a job."
