#!/bin/zsh
# Run a script repeatedly until fail
# Idea from http://stackoverflow.com/questions/12967232/repeatedly-run-a-shell-command-until-it-fails
# If this is in your home dir you can just run it as 
# ~/untilfail.sh "some command to run". Running maven tests are good ones 
# ~/untilfail.sh "mvn test -Dtest=org.sakaiproject.sitestats.test.StatsUpdateManagerTest"

#shopt -s expand_aliases
#I have important functions and aliases in here
