linux question 3

  1. (10 points) The output from the command ls -l /usr/bin/at shows:
    -rwsr-sr-x 1 daemon daemon 51464 Feb 19  2018 /usr/bin/at_x000D_

    What do the two “s”es in the permissions mean, and what is the effect on the process created when you run this program?

  2. (10 points) Give a Linux command to print dictionary words that contain the vowels ‘a’, ‘e’, ‘i’, ‘o’, ‘u’, and ‘y’ in that order. Show your output.
    Hint: The file /usr/share/dict/words is a dictionary of English words.
