CLI utility for text search / replace.

Project description

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.

Installation and usage

To install, simply run pip install command. You need at least Python 3.6 interpreter.

pip install psed

$ psed --help
