Using Input/Output Redirection and Analyzing Text on RHEL 8

In this lab, you're a mid-level systems administrator who is tasked with generating text log files from queries and manipulating that text to produce usable reports. You'll use features such as command substitution, redirection, file creation, appending to existing files, and directing standard output and standard error in order to remove bad data and produce your reports with usable data.

You'll then use find and grep to search not only for existing files but also for strings that are contained in files. You'll also be counting the output, discarding unusable output, and verifying that your searches yield proper results. Finally, you'll use grep in an alternative fashion to first find search strings using various display options and then apply additional useful output options to create usable reports with all needed information.

Red Hat Exam Requirements Covered:

• Use input-output redirection (>, >>, |, 2>, etc.)
• Use grep and regular expressions to analyze text
