Someone one was trying to find out something, according to the following UNIX commands.

   $ ssh I@world
Password: 
   [world ~]$ who -H
USER     LINE     WHEN
I        terminal 1865

Who was it? And to what famous quote does it refer to?

I think it was

Alice

and the quote is

Who in the world am I? Ah, that's the great puzzle.

Explanation for those not familiar with SSH:

$ ssh I@world starts an SSH shell and logs in to "world" as user "I"
Next, you type in your password (obviously not visible. I wonder what it is).
who -H in the SSH shell gives a list of users currently logged in. The -H option tells the program to write column headings (USER, LINE, WHEN)

Explanation for the year:

Alice in Wonderland was published in 1865

  • $\begingroup$ I'm a bit sad you did not state the whole quote ... ;) $\endgroup$ – fffred May 19 '16 at 20:18
  • $\begingroup$ @fffred Well, the code doesn't seem to contain a reference to the second part of the quote... $\endgroup$ – BaSzAt May 19 '16 at 21:30
  • $\begingroup$ @BaSzAt, correct, but it gives the connection to the title $\endgroup$ – fffred May 19 '16 at 22:00
