Which of the following are valid permissions for a directory where the command chmod 1777 has been used to set the permissions on it? a. Srwxrwxrwx b. drwxrwxrwt c. drwxrwxrw- d. trwxrwxrwx

The correct option is b. drwxrwxrwt

Explanation:

You may use the chmod command to set permissions in one of the two modes. They are Absolute Mode where one uses numbers to represent file permissions. When you modify using absolute mode, you make permissions for each triplet by an octal mode number.  Similarly, in Symbolic Mode, you use combinations of letters and symbols to add or remove permissions. You may set special permissions on a file in the absolute or symbolic modes. In absolute or symbolic mode, if you are not the owner, become superuser. You can then change permissions using the chmod command. In the question, chmod command 1777 drwxrwxrwt is used to set valid permissions.Run the following command in the terminal, within a folder containing the directory you wanted to change permissions. Here, the directory name is "yourDirectory" .  $ chmod 1777 yourDirectory/ . Change directory permissions, and the files contained within it using the recursive option.  $ chmod -R 1777 yourDirectory/  . Confirming your change, your directory's symbolic permissions should now be "drwxrwxrwt"
