Question description

  1. The file called /etc/shadow contains the encrypted passwords of all the users on the UNIX system.  The permissions on this file are set to rw-r----- (read-write for the root user, read for the shadow group)

A. True

B. False

This is what I did and got:

I ls -l /etc/shadow and got -rw-r----l root shadow 1296 Aug 24 2012 /etc/shadow

 The answer is true correct?

  2. cd to my home directory. Within my home directory there is a sub-directory called scripts.

A.) What permissions would I need to ADD to the sub-directory called scripts that would allow you to cd into it and view the files. Give me the MINIMUM permissions necessary to do this? (In other words, do not make the directory perms 777)

Hint: Are we in the same LINUX group?  Use the id command to verify this.

A. I would need to add read perms for other.

B. I would need to add read and execute perms for other.

C. I would need to add read perms for group.

D. I would need to add read and write perms for group.

Going by what I have learned I think the answer is D.But can't verify it by excuting the commands. What commands would I use to verify the answer?
