Script for installing git on a Linux machine (tested on Ubuntu 16.04) and requires 'sudo' permission

install-git.sh

directory=/home/user

if [ -z ${1+x} ]; then echo "No argument passed, using version $gitVersion"; else gitVersion=$1; fi

sudo rm -R --interactive=never git-$gitVersion

I made this for my own use, but realized it would be useful for others. Please note the two lines of statements:

sudo make prefix=/usr profile
sudo make prefix=/usr PROFILE=BUILD install install-doc install-html install-info

This will optimize the installation so once installed Git runs faster. This means it will take 2 hours or so for the entire script to finish
