How to install and use homebrew! A Mac OSX Package Manager

What is Homebrew?

homebrew is known as “The Missing Package Manager for macOS”.

It is used to install the UNIX tools Apple didn’t include with macOS in an extremely easy and flexible manner.

Prerequisites

How to install it on MacOSX?

Install xcode developer tools.

rakesh_jain@my-mac ~ % xcode-select --install

Now install homebrew:

rakesh_jain@my-mac ~ % /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

You will be prompted to enter sudo password a few times during the installation process.

Verify the installation:

rakesh_jain@my-mac ~ % brew --versionHomebrew 3.2.13Homebrew/homebrew-core (git revision 753dedc193; last commit 2021-09-22)

Homebrew Shell Completion — BASH / ZSH

Homebrew comes with completion definitions for the brew command.

zsh, bash and fish are currently supported.

If you have zsh shell ->

rakesh_jain@my-mac ~ % echo $SHELL
/bin/zsh

To make Homebrew’s completions available in zsh, you must get the Homebrew-managed zsh site-functions on your FPATH before initialising zsh’s completion facility. Add the following to your ~/.zshrc file:

rakesh_jain@my-mac ~ % cat .zshrc 
if type brew &>/dev/null
then
FPATH="$(brew --prefix)/share/zsh/site-functions:${FPATH}"
autoload -Uz compinit
compinit
fi

If you have bash shell ->

To make Homebrew’s completions available in bash, you must source the definitions as part of your shell’s startup. Add the following to your ~/.bash_profile (or, if it doesn’t exist, ~/.profile):

rakesh_jain@my-mac ~ % cat .bash_profileif type brew &>/dev/null
then
HOMEBREW_PREFIX="$(brew --prefix)"
if [[ -r "${HOMEBREW_PREFIX}/etc/profile.d/bash_completion.sh" ]]
then
source "${HOMEBREW_PREFIX}/etc/profile.d/bash_completion.sh"
else
for
COMPLETION in "${HOMEBREW_PREFIX}/etc/bash_completion.d/"*
do
[[ -r "${COMPLETION}" ]] && source "${COMPLETION}"
done
fi
fi

If you install the bash-completion formula, this will automatically source the completions’ initialisation script (so you do not need to follow the instructions in the caveats).

How to install unix tools with homebrew ?

The homebrew is now installed on you system and you can use it to install various unix tools.

Syntax:

rakesh_jain@my-mac ~ % brew install <package_name>

For example here I will be installing ansible configuration management tool on my Mac Book:

rakesh_jain@my-mac ~ % brew install ansible

How to search package with homebrew?

You can search or list available packages by running following commands :

Syntax:

rakesh_jain@my-mac ~ % brew search <package_name>

Example:

rakesh_jain@my-mac ~ % brew search docker

docker docker-credential-helper-ecr docker-machine-driver-vmware docker-squash
docker-clean docker-gen docker-machine-driver-vultr docker-swarm
