To Our Valued Readers:
Sybex is proud to have served as a member of CompTIA's Linux+ Advisory Committee. Just as CompTIA
is committed to establishing measurable standards for certifying individuals who will support Linux
systems in the future, Sybex is committed to providing those individuals with the skills needed to meet
those standards. By working alongside CompTIA, and in conjunction with other esteemed members
of the Linux+ committee, it is our desire to help bridge the knowledge and skills gap that currently con-
fronts the IT industry.
Sybex expects the Linux+ program to be well received, both by companies seeking qualified technical
staff and by the IT training community. Along with the existing line of vendor-neutral certifications
from CompTIA, including A+, Network+, Server+, and i-Net+, the Linux+ certification should prove
to be an invaluable asset in the years ahead.
is comprehensive,
in-depth, and pedagogically sound. We’re confident that this book will meet and exceed the demanding
standards of the certification marketplace and help you, the Linux+ exam candidate, succeed in your
endeavors.
Linux+ Study Guide
Good luck in pursuit of your Linux+ certification!
