LineByter is a utility designed to find and extract patterns from text files. It’s free for personal use.

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.)

Recently the program was reviewed on DonationCoder.com:

“This program far exceeded my expectations and desires.  It is more generally useful than the program i initially wanted, but the simple interface and the use of presets and saved profiles means that i can use it to extract emails from a file with just one or two clicks, and once i configure a profile to reject the patterns i want rejected, i never have to mess with those settings again.

There are some very powerful search/grep tools available — this program is not meant to be a completely general purpose search tool.  It’s much more focused at people who perform repeated extraction of data from files, using some common patterns that they have use for again and again.  If you need such a program, this is a miracle tool.”
