Which of the following commands is used to assign executable permission to the owner of the file named “note”? A. chmod g+x note B. chmod u+w note C. chmod u+x note D. chmod ugo+x note E. None of the above

chmod g+x note
chmod u+w note
chmod u+x note
chmod ugo+x note E. None of the above

The correct answer is C. chmod u+x note.

The chmod command is used to change the permissions of a file. The u option specifies the owner of the file, the + option adds permissions, and the x option allows the file to be executed. Therefore, the command chmod u+x note will add executable permission to the owner of the file named “note”.

The other options are incorrect for the following reasons:

  • Option A, chmod g+x note, would add executable permission to the group that owns the file.
  • Option B, chmod u+w note, would add write permission to the owner of the file.
  • Option D, chmod ugo+x note, would add executable permission to the owner, group, and other users of the file.
  • Option E, None of the above, is incorrect because it is not a valid command.
