What is McFly History?
McFly replaces the default Ctrl-R shell history search with an advanced, intelligent search engine. It prioritizes command suggestions in real-time using a small neural network, taking into account factors like your current working directory, the context of recently executed commands, how often and when you ran a command, and its exit status. This ensures that the most relevant commands are always at the top of your suggestions.
This tool is designed for developers, system administrators, and anyone who frequently uses the command line in Zsh, Bash, or PowerShell. It aims to significantly boost productivity by making shell history navigation more intuitive and efficient, reducing the time spent searching for past commands. McFly maintains compatibility with your existing shell history files, allowing for easy adoption and removal.
