This was actually what got me hooked during university.

Had to plot about 40 txt files of measurement data, was not looking forward to do it one by one with the GUI-based tool I had.

StudyBuddy: “Do you have a Linux on this Laptop”?

Me: “Yeah, set up dual boot a while ago, never really wound up using it.”

StudyBuddy: Boots up Linux, installs gnuplot, types in a one liner.

Computer: Brrrrt. Here’s your 40 plots.

Me: “Okay, I’ve got to start looking into this.”
