GL120: Linux Fundamentals

Days: 5 Prerequisites: Students should be comfortable with computers. No familiarity with Linux or other Unix operating systems is required. Audience: This course is ideal for those who need to gain proficiency in Linux and Unix. Description: The GL120 is a challenging course that focuses on the fundamental tools and concepts of Linux and Unix. Students gain proficiency using the command line. Beginners develop a solid foundation in Unix, while advanced users discover patterns and fill in gaps in their knowledge. Like all Guru Labs courses, the course material is designed to provide extensive hands-on experience. Topics include: basic file manipulation; basic and advanced filesystem features; I/O redirection and pipes; text manipulation and regular expressions; managing jobs and processes; vi, the standard Unix editor; automating tasks with shell scripts; managing software; secure remote administration; and more.
