Ruby Scripting: Count Words and Lines in Text Files

Understanding the structure and content of text files is a fundamental skill in programming and data analysis. Many tasks involve extracting insights from text, and the ability to programmatically count words and lines is a valuable first step. By the end of this course, you will be able to write robust Ruby scripts that can read text files, handle command-line inputs, and accurately report word and line counts. What you'll learn: * Understand core Ruby concepts for file input and output operations. * Learn to read and process text files line by line and character by character. * Apply Ruby string manipulation methods to accurately count words. * Configure your scripts to accept file paths as command-line arguments. * Implement basic error handling for common file operation issues. * Practice writing clean, readable, and modular Ruby code for scripting. * Explore using Ruby's standard library modules for robust file handling. The course begins with an introduction to Ruby's file handling capabilities, then progresses to practical techniques for reading and parsing text. You will then learn to integrate command-line arguments and build a complete, functional script with error handling. This course is designed for absolute beginners in programming and those new to Ruby who want to build practical scripting skills. No prior programming experience is required.
