This project reproduces Ubuntu’s command-not-found for Homebrew users on
macOS.
On Ubuntu, when you try to use a command that doesn’t exist locally but is
available through a package, Bash will suggest you a command to install it.
Using this script, you can replicate this feature on macOS:
# on Ubuntu
$ when
The program 'when' is currently not installed. You can install it by typing:
sudo apt-get install when
# on macOS with Homebrew
$ when
The program 'when' is currently not installed. You can install it by typing:
brew install when
Over 5000 formulae are supported, representing more than 17000 different commands
(100% of the main Homebrew repo).
Install
First, tap this repository:
brew tap homebrew/command-not-found
Bash and Zsh: Add the following line to your ~/.bash_profile (bash) or ~/.zshrc (zsh):
When you tap the repo you’ll get two more brew commands: brew which-formula
and brew which-update. The first one uses a database file which gives you the
formula you have to install in order to get a specific command. The file is
generated by the second command by crawling all installed formulae and
collecting their binaries. Having this as a tap means you get an up-to-date
binaries database each time you run brew update.
The handler.sh script defines a command_not_found_handle function which is
used by Bash when you try a command that doesn’t exist. The function calls
brew which-formula on your command, and if it finds a match it’ll print it to
you. If not, you’ll get an error as expected.
