In the Tron legacy film trailer at 1:12, you can see a terminal displaying the output of the top(1) command, a traditional UNIX command to display the list of running processes. It is funny that the machine is only showing 9 days of uptime though, it should be longer than that. This is like Trinity using ssh(1) commands in the second Matrix movie to get into the mainframe and shut down the power so that Neo could get to the Architect. They are using the machine as root instead of using sudo as I do, but it is good to see something other than Microsoft Windows or macOS shown on the big screen. There was also the 3D computer interface shown in Jurassic Park, that was based on an actual program, a UNIX 3D file manager that was available a while ago. I am sure that in the first Tron film, it was an arcade game machine that sucked the protagonist into the computer world, that was a good movie. There was even a South Park episode where one of the characters was sucked into the computer through the webcam and was trapped in the world of Facebook. That episode was very funny.
From the top(1) man page:
The top program provides a dynamic real-time view of a running system. It can display system summary information as well as a list of tasks being managed by the Linux kernel. The types of system summary information shown and the types, order and size of information displayed for tasks are all user-configurable. That configuration can be made persistent across restarts.
Example usage of the top(1) command.
