McFly is a Rust-based CLI tool that replaces the default ctrl-r shell history search with an intelligent, context-aware search engine. It prioritizes command suggestions in real time using a small neural network and stores extended history metadata in a SQLite database.

Use cases

• search shell history intelligently with ctrl-r
• find commands I ran in this directory before
• avoid re-running previously failed commands
• scrub sensitive commands from shell history
• track command exit status and timestamps
• get history suggestions based on recently executed commands

When to choose

• you use Bash, Zsh, Fish, or PowerShell and want a smarter ctrl-r
• you want history search that considers working directory and command context
• you want a fast, safe Rust tool that keeps your normal history file intact

When to avoid

• you need a tool with active maintenance and quick bug fixes
• you use a shell other than Bash, Zsh, Fish, or PowerShell
• you prefer simple plain-text history search without a database
