Is it
"I am your father", Vader's famous quote to Luke from Star Wars: Episode V – The Empire Strikes Back (1980) ?
since
I think the first command gives the pid of the parent of the specified process, and the second line confirms that the current process is that process.

3$\begingroup$ Exactly right. For completeness you should also give the movie title, although I guess everyone will immediately know it after reading the quote. $\endgroup$– celtschkOct 17, 2018 at 19:19

$\begingroup$ Actually, Darth Vader doesn't say "Luke, I am your father" - he says "No, I am your father". youtu.be/RgDPi5WvC8M?t=92 $\endgroup$ Oct 17, 2018 at 22:30

6$\begingroup$ My answer doesn't say Luke either... What exactly are you correcting? $\endgroup$– EmnephoOct 17, 2018 at 22:35

Hmmm, I think it's
"We're the same, you and me. We're the same, don't you see?" from Falling Down, 1993
Reasoning: Your first command gives the pid of the process designated by $u. The second command gives the pid of the current bash process that you are running. Since both pid's are equivalent, u (you) and the current bash session (me) are the same.

2$\begingroup$ Sorry, but your description of what the first command does is wrong, and consequently so is your conclusion. But you also got quite a few things right. $\endgroup$– celtschkOct 17, 2018 at 19:03
