Slightly modified version of https://raw.githubusercontent.com/grrnikos/pma/master/pma.sh to support one argument, the URL to serve the site on.

phpmyadmin.sh

#!/bin/bash

LATEST_VERSION=$(curl -sS 'https://api.github.com/repos/phpmyadmin/phpmyadmin/releases/latest' | awk -F '"' '/tag_name/{print $4}')
DOWNLOAD_URL="https://api.github.com/repos/phpmyadmin/phpmyadmin/tarball/$LATEST_VERSION"
SERVE_URL=${1:-phpmyadmin.local}

echo "Downloading phpMyAdmin $LATEST_VERSION"
wget $DOWNLOAD_URL -q -O 'phpmyadmin.tar.gz'

mkdir phpmyadmin && tar xf phpmyadmin.tar.gz -C phpmyadmin --strip-components 1

rm phpmyadmin.tar.gz

Usage

You would use it like this:

curl -s -S https://gist.githubusercontent.com/Braunson/f7205b83bef1acfb2fe833fdefd30271/raw/phpmyadmin.sh | bash -s phpmyadmin.local

or for a shorter snippet

curl -s -S -L https://bit.ly/2YsR9wo | bash -s phpmyadmin.local
