Homebrew tap for leech — a CLI download manager written in Go.

brew tap vigo/leech
brew install leech

Homebrew's official cask registry has an app called Leech (a GUI download manager by Many Tricks). If that cask is installed, brew install leech will install the formula but skip linking the binary. To fix this:

brew install vigo/leech/leech
brew link --overwrite leech

brew update
brew upgrade leech
