I am pleased to announce a new version of my Ruby One-Liners Guide ebook. Examples, exercises, solutions, descriptions and external links were added/updated/corrected.
When it comes to command line text processing, there are several well known tools like grep for filtering, sed for substitution and awk for field processing. Compared to such tools, Ruby has a feature rich regular expression engine, plenty of builtin modules and a thriving ecosystem. Another advantage is that Ruby is more portable.
This ebook will show examples for filtering and substitution features, field processing, using standard and third-party modules, multiple file processing, how to construct solutions that depend on multiple records, how to compare records and fields between two or more files, how to identify duplicates while maintaining input order and so on.
