quickly install homebrew on Amazon Linux 2

install-brew-for-a-dev-on-Amazon-linux2.sh

#!/usr/bin/bash
#  on amazon linux II my developers can not run sudo and more importantly no user has a password.
# installing linuxbrew/homebrew is a pain unless you do this: 
# as root ( or sudo from the admin user ) 
mkdir -p /home/linuxbrew/
chown $THE_DEV_USERNAME: /home/linuxbrew/
#### root/admin work is done !!!! 
# then the developer themselves can run the rest: 
#
# as THE_DEV_USERNAME person 
# i.e. 
sudo -u $THE_DEV_USERNAME 
#
mkdir /home/linuxbrew/.linuxbrew/
git clone https://github.com/Homebrew/brew /home/linuxbrew/.linuxbrew/Homebrew
mkdir /home/linuxbrew/.linuxbrew/bin
ln -s /home/linuxbrew/.linuxbrew/Homebrew/bin/brew   /home/linuxbrew/.linuxbrew/bin/brew
eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)
# note - 
# REMEMBER TO  add line 10 to .bashrc for THE_DEV_USERNAME !

Thanks for the script! 🙏 In my case, I'm a developer who's given full access to my own isolated machine (VM) on EC2 by my admin user, so I adapted the script:

#! /usr/bin/bash

THE_DEV_USERNAME=ec2-user

mkdir -p /home/linuxbrew/
chown $THE_DEV_USERNAME: /home/linuxbrew/

sudo -u $THE_DEV_USERNAME bash <<EOF
mkdir /home/linuxbrew/.linuxbrew/
git clone https://github.com/Homebrew/brew /home/linuxbrew/.linuxbrew/Homebrew
mkdir /home/linuxbrew/.linuxbrew/bin/
ln -s /home/linuxbrew/.linuxbrew/Homebrew/bin/brew /home/linuxbrew/.linuxbrew/bin/brew
eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)
EOF
