Unix Basics Practice Test: Awk Command Operations — Flashcards

AWK is a pattern-action language that is designed for processing text files. It is often used to extract specific data from files, format data, and perform calculations on data. AWK is a very efficient language for processing large text files, and it is often used in shell scripts and other Unix utilities.

Here are some of the common operations that can be performed using AWK:
Scanning files line by line: AWK can read a file line by line and process each line individually.
Splitting each input line into fields: AWK can split each input line into fields based on a delimiter, such as a space, comma, or tab.
Comparing input lines and fields to patterns: AWK can compare input lines and fields to patterns and perform actions based on the results of the comparison.
Performing specified actions on matching lines: AWK can perform specified actions on matching lines, such as printing the line, modifying the line, or saving the line to a file.
