Provides the essential skills and hands-on experience needed to be proficient at the UNIX or Linux command line. This challenging course focuses on the fundamental concepts and tools which make UNIX and Linux so powerful. Students in this course commonly span a variety of skill levels, from beginners desiring a solid foundation in UNIX to experienced users seeking to fill in gaps in their knowledge. Subjects focused on during this class include the Linux filesystem and how to manipulate it; the basic UNIX and Linux notions of pipes, redirection, regular expressions, and other tools for performing complex tasks; the management of processes and jobs; vi, the standard UNIX editor; and the ability to construct shell
scripts to automate routine or difficult operations.
This course is taught using Fedora Core 3.
Prerequisites: general understanding of computing functions, basic typing skills.
