# Yet another movie line on the Linux terminal

What famous quote does the following terminal session refer to?

$$ps -o ppid= -p$$u
28342
$echo$$28342  • That doesn't look like the YAML I know. =x – jpmc26 Oct 18 '18 at 1:28 ## 2 Answers 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. • Exactly right. For completeness you should also give the movie title, although I guess everyone will immediately know it after reading the quote. – celtschk Oct 17 '18 at 19:19 • True, edited to include movie title and character details nonetheless – Emnepho Oct 17 '18 at 19:21 • Actually, Darth Vader doesn't say "Luke, I am your father" - he says "No, I am your father". youtu.be/RgDPi5WvC8M?t=92 – Baard Kopperud Oct 17 '18 at 22:30 • My answer doesn't say Luke either... What exactly are you correcting? – Emnepho Oct 17 '18 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.

• 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. – celtschk Oct 17 '18 at 19:03
