Which of the following commands is used to absolutely assign all permissions to the owner, read and write permissions to the group and only executable permission to the others of the file note? A. chmod 761 note B. chmod 671 note C. chmod 167 note D. chmod 4=rwx, g=rw note E. None of the above

chmod 761 note
chmod 671 note
chmod 167 note
chmod 4=rwx, g=rw note E. None of the above

The correct answer is: A. chmod 761 note

The chmod command is used to change the permissions of a file. The first three digits of the chmod command represent the permissions for the owner, group, and others, respectively. The permissions are represented by the following letters:

  • r – read
  • w – write
  • x – execute

The fourth digit of the chmod command is a special flag that can be used to set the sticky bit or the set-user-ID or set-group-ID bit.

In this case, we want to assign all permissions to the owner, read and write permissions to the group, and only executable permission to the others. This can be done by using the following chmod command:

chmod 761 note

The 7 in the first position indicates that the owner has read, write, and execute permissions. The 6 in the second position indicates that the group has read and write permissions. The 1 in the third position indicates that others have only executable permission.

The following table shows the permissions that are assigned to each user based on the chmod command:

| User | Permission |
|—|—|
| Owner | rwx |
| Group | rw |
| Others | x |

I hope this helps! Let me know if you have any other questions.
