How

which for your executables.

A Linux/MacOS CLI to discover which package manager installed a command.

Useful when updating, removing, or troubleshooting packages.

Usage

how <command>

Tells you which package managers installed <command>. Also resolves the command via type first, so you see whether it's an executable path, a shell alias, function, or builtin — and alias targets are followed before the package-manager checks run.

Example

$ how git
> git installed by apt

$ how starship
> starship installed by cargo
> starship installed by brew

Installation

You must have Rust installed. If you don't, you can install it with rustup.

Then, run:

cargo install --git https://github.com/danilofuchs/how.git

Requires a POSIX sh in PATH (used to invoke type).
