AWK Text Processing and Scripting in the Bash Shell

Raw text files, system logs, and CSV data can be overwhelming to process manually, but learning to automate these tasks saves hours of tedious work. This course teaches you how to harness the power of the AWK text-processing language to manipulate data with precision right from your terminal. You will transition from writing basic command-line filters to constructing robust text-processing scripts. What you'll learn: Understand core AWK concepts, including records, fields, and the basic pattern-action structure; Use built-in variables like FS, OFS, NR, and NF to control how data is read and formatted; Apply regular expressions within AWK to isolate and extract specific data patterns; Perform arithmetic and string operations to calculate totals, averages, and reformat text; Construct multi-line AWK scripts with BEGIN and END blocks for complex data reporting; Integrate AWK seamlessly into modern Bash pipelines and shell scripts. We begin with foundational concepts, defining how AWK views text files as structured databases, before moving into practical scripting patterns and real-world log analysis. This course is designed for beginners, system administrators, and data enthusiasts looking to improve their command-line efficiency, with no prior scripting experience required.
