I'll answer to unzip. In the post, I'm using a Linux distribution called Kali Linux. Kali is the successor to BackTrack Linux. Most people who use my software, use it with Kali Linux.
Kali is a distribution with a focus on offensive security. Most tools require root to run. It's very rare to find a Kali user who uses sudo and works from a non-root account. root for all actions is normal.
Some people may use Kali day to day, but it's built to do a job.
I didn't call out Kali specifically, but all of my screenshots show Kali's default window manager theme. I don't know if my audience earns the "hacker" badge by your standards... but I suspect most of them recognize Kali from a distance.
