ubuntu@cyberithub:~$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
==> Checking for `sudo` access (which may request your password)...
==> This script will install:
/home/linuxbrew/.linuxbrew/bin/brew
/home/linuxbrew/.linuxbrew/share/doc/homebrew
/home/linuxbrew/.linuxbrew/share/man/man1/brew.1
/home/linuxbrew/.linuxbrew/share/zsh/site-functions/_brew
/home/linuxbrew/.linuxbrew/etc/bash_completion.d/brew
/home/linuxbrew/.linuxbrew/Homebrew
==> The following new directories will be created:
/home/linuxbrew/.linuxbrew/bin
/home/linuxbrew/.linuxbrew/etc
/home/linuxbrew/.linuxbrew/include
/home/linuxbrew/.linuxbrew/lib
/home/linuxbrew/.linuxbrew/sbin
/home/linuxbrew/.linuxbrew/share
......................................

Step 5: Add Homebrew to Your Path

After successful installation, you will see the information to add Homebrew in System's PATH. You can just copy paste the command from output and run as shown below. This will add the brew binary path to local user's profile. It will help System understand where to find the brew tool if someone uses this command.

ubuntu@cyberithub:~$ echo 'eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"' >> /home/ubuntu/.profile
ubuntu@cyberithub:~$ eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"

Step 6: Verify Installation

It is now time to test the installation by running brew doctor command. This will tell if brew command will work properly in your System. After running this command, if you see output like below then you are good to go.

ubuntu@cyberithub:~$ brew doctor
Your system is ready to brew.

Step 7: Install a Package Using brew

You can now really use the brew package manager to install any new package. For example, here I am installing wget package using brew install wget command as you can see below. This will install the package along with all its dependencies.

ubuntu@cyberithub:~$ brew install wget
