In The Matrix 2, Trinity uses nmap to check for an ssh exploit, then cracks it using a cli tool, all from Linux.

Edit: The ssh exploit was a real, known vulnerability at the time.

Ubuntu in Nobody (slightly nsfw), great movie too.

It checks all the boxes. Pinging some random IP, checking their python version, installing pip updates, the output of ls -l /etc, all in a virtualbox VM. Clearly a professional hacker. /s

Since you say media and not specifically show or movie.

There's a manga based on ubuntu: https://en.wikipedia.org/wiki/Ubunchu!

The story follows the activities of the three members of the Ichinomiya Prefectural High School's system administration club (part of the wider IT club). Each chapter is focused on a certain aspect of the Ubuntu operating system or a related topic, such as command-line interfaces, input methods, Linux Mint, or software licensing.

In addition to the stuff already listed:

In the Swedish film version of "The Girl with the Dragon Tattoo", Lisbeth and the hacker dude use Ubuntu, especially in the scene where they recover the stuff from Lisbeth's broken laptop. (In the US version, they decided to use Macs instead. And included a scene where she goes to an Apple store with the broken laptop and they helpfully tell her shit's unfixable. Realism.)

Jurassic Park. Though at the time I suppose it could have been a more direct Unix descendant.

Wayne's World 2 (yes there's a 2) Garth talks to a girl about the Unix book she's carrying.

Antitrust, but that's kind of cheating

In the Iron Man movies his server cluster is a couple of Oracle racks, so probably running either Solaris or Oracle Linux.

I mean, you see it a lot in local or low to mid budget network TV. They dress up the laptop to make it look like apple hardware (usually a pear logo instead of an Apple), but when you get a glimpse of the DE, it is clearly neither windows nor apple.

Tv writers and other liberal arts types tend to be cult-like in their devotion to apple, but I guess network TV prop departments have decided apple is too expensive, and installing windows is too much of a hassle.

I think it’s in the Rick and Morty episode where Rick is guarding his special toilet that shows his underground hideout computer booting Debian 3 or something.

Teacher of main character uses linux "TONIKAWA: Over the Moon for You" first episode 04:55 time

I could be wrong but as far as I remember the computer guy in Dredd (2012) was using Linux and had openssh running in the terminal

In the book The Martian, the computers built into the rovers apparently run Linux, or at least some *Nix. At one point they have Watney run hexedit on /usr/lib/habcomm.so and change a number of bytes to hack it to talk to Pathfinder.

The live action series of the manga Trillion Game has a developer as one of the characters and some of fhe stuff he does uses actual terminology and logic, and not just a bunch of tech jargon strewn together.

This show made me so mad. The premise was so good and now it's just ugh

I swear there was some movie that actually showed off kali or its predecessor backtrack, but now I can't remember

Also iirc the main control computer on elysium was a unix prompt and I'm pretty sure it showed some SQL adding citizens from Earth lol.
