Answer #1

Command to grant given permissions is: chmod 761 final_exam

Explanation:

  • 7 refers to owner access, where 7 in binary form is 111, first 1 represent read access, second 1 represents write access and last 1 represents execute access.
  • 6 refers to group access, where 6 in binary form is 110, first 1 represent read access, second 1 represents write access and last 0 represents execution access is not given.
  • 1 refers to others like public access, where 1 in binary form is 001, first 0 represent read access is not given, second 0 represents write access is not given and last 1 represents execution access is given.

So using the given command, we can set the required permissions to file named "final-exam".

Mention in comments if any mistakes or errors are found. Thank you.
