brew Shell Completion
brew Shell Completion Homebrew comes with completion definitions for the brew command. Some packages also provide completion definitions for their own programs. zsh, bash and fish are currently supported. You must manually configure your shell to enable its completion support.

How do I run a program with a different working directory from current, from Linux shell?
Using a Linux shell, how do I start a program with a different working directory from the current working directory? For example, I have a binary file helloworld that creates the file hello-world.txt in the current directory. This file is inside of directory /a. Currently, I am in the directory /b. I want to start my program running ../a/helloworld and get the hello-world.txt somewhere in a third
