A little wrapper script to run RVM-based Ruby interpreters from cron

rvm-ruby.sh

#!/bin/bash

if [[ -z ${2} ]]; then
  echo "$0 <ruby interpreter|'default'> <arguments to ruby interpreter>"
  exit 1
fi

if [[ -s /opt/rvm/scripts/rvm ]] ; then source /opt/rvm/scripts/rvm ; fi

rvm use "${1}"

ruby "${@:2}"
