Using Input/Output Redirection and Analyzing Text on RHEL 8

A Linux system administrator's life is filled with text files and data. It's easier to make sense of this mountain of data using the `grep` utility combined with the power of regular expressions. Input/output redirection is also an important skill for Linux system administrators, who can use it to create log files, quiet error messages, manipulate and sort data, and more. In this hands-on lab, we will explore input/output redirection as well as use `grep` and regular expressions to analyze and manipulate text. *This course is not approved or sponsored by Red Hat.*
