I do windows system Administration (Active Directory, Exchange emai server 2003, WSUS, Folders NTFS permissions).
I have heard that Unix/Linux is a must to learn for the future. Now I have some questions:
1- Do I need to learn Unix or Lunix and which flavor should I pick in order to do the same tasks I mentionned above under windows system administration?
2- which book would you recommend that will enable me to learn and administer Unix or Linux system?
I would like to have a book that teaches how to achieve the same tasks I do under windows system administrator?
