LineByter is a utility designed to find and extract patterns from text files.

It includes some unique features like duplicate removal and the ability to specify multiple match and reject patterns, that make it ideal for doing things like extracting emails or urls from text files.

Features:

• You can drag and drop as many files to scan as you want.
• Nice progress bar so you can see how much more time it’s going to take.
• Supports preset library of regular expressions so you can easily just select common patterns and add your own presets — this is super important for letting you quickly reuse patterns.
• Lets you specify a list of multiple patterns that are being searched for and how to extract the data you want from these patterns.
• Lets you specify a list of additional patterns which should be rejected even if they match the first list (ideal if you want to find and extract all email patterns except those with certain properties).
• Shows a nice complete report of why each pattern was found and/or rejected.
• Automatically removes duplicates.
• Produces final list of results that can be copied to clipboard or saved to file.
• You can save and load profiles that have your settings (files, patterns, etc.)
