Bash function so you can just say install packageName regardless of apt or yum distro

universal-install.sh

#!/bin/bash

install(){
  isApt=`command -v apt-get`
  isYum=`command -v yum`
	package=$1
	if [ -n "$isApt" ]; then
	    apt-get -y install $package
	elif [ -n "$isYum" ]; then
	    yum -y install $package
	else
	    echo "Err: no path to apt-get or yum" >&2;
	    exit 1;
	fi
}
