My coworker doesn't know how to use a terminal. He talked himself into his position and instead of taking the time to learn about the basic commands he keeps asking someone else (including the teammanager, who's actually a software engineer) to do things for him.
For reference; we need the terminal to tail log files, keep track of processes, cron jobs, manipulate file structures, use scp (I use sshfs) to move things between other workstations and servers etc. Being able to use a terminal is one of the basic requirements for our job.

What.
Why.
How.

Why do people do this?
