Linux Training Overview
This course helps you prepare for the CompTIA Linux+ Certification exam. The course teaches Linux user commands, shell script programming, and essential Linux system administration tasks. Note that completion of this course alone is not adequate preparation to pass the exam. The actual Linux+ Certification is designed to measure the competencies of Linux professionals who have six to twelve months of practical experience with the Linux operating system. Thus, after this course you need more study, practice, and experience prior to taking the exam.
Linux Training Audience
Users who are new to Linux and seeking the CompTIA Certification in Linux+.
Linux Training Prerequisites
We assume that you have used a computer before and have a basic understanding of how to interact with one. Any previous UNIX or Linux experience you may have will be very helpful, whether as a user, administrator, or programmer.
