• A summary of the Regex 101 module from regexlearn
• Self-collection of regex patterns
• Regex for productivity hacks

⚒ Usage

• Use Regex-101 as a reference for the concepts regarding regular expressions

  • Examples follow three column structure: | Input file | regex | matched text |

• Check the Regex for Productivity collection for reuse or tweak it to your own need.

  • To run through Git Bash on Windows, execute $ grep -oP <REGEX> <FILE>
  • Options:
    • -o show only the matches, not entire lines
    • -P enables interpretation of PCRE (Perl Compatible Regular Expressions)
