Book to learn system administration using CentOS Linux?

In summary, when looking for a book on Linux administration, it is recommended to search on Amazon for up-to-date options with helpful reviews and ratings. While books can be useful as a backup resource, day-to-day administrators often rely on online resources such as man pages and online forums for solutions. However, reading a book alone is not enough to become a skilled systems administrator; practice and hands-on experience are crucial in this field. Many experienced sysadmins also seek out hacker books to further their knowledge and protect their systems.
