psed's Introduction

psed

CLI utility for text search / replace.

This project is a simple replacement for the sed in Linux. I had enough issues with debugging the regular expressions, especially a few months after they were written, so I have created a replacement in Python. Feel free to use it, but the project aimed to cover my use case so it might not fit everybody. I plan to improve functionality in the future.
