Learn about various commands available for common and exotic text processing needs. Examples have been tested on GNU/Linux - there'd be syntax/feature variations with other distributions, consult their respective man
pages for details.
Individual online ebooks with better formatting, explanations, exercises, solutions, etc:
- CLI text processing with GNU grep and ripgrep
- CLI text processing with GNU sed
- CLI text processing with GNU awk
- Ruby One-Liners Guide
- Perl One-Liners Guide
- CLI text processing with GNU Coreutils
- Linux Command Line Computing
See https://learnbyexample.github.io/books/ for links to PDF/EPUB versions and other ebooks.
