A silly little bash script for checking if a site is up. usage: ./isu.sh sitetocheck.com

isu.sh

#!/bin/sh

siteResponse=`curl -s -I $1 | grep HTTP/1.1 | awk {'print $2'}`

if [ $siteResponse = 200 ]; then
  echo "Looks like your site responded with a" $siteResponse "and is fine, be happy!"
else
  echo "rut ro! Looks like your site responded with a" $siteResponse "and that's not right, go fix it!"
  case $siteResponse in
    301 )
      echo "aaah, it's a 301, no prob right?";;
    500 )
      echo $2 "is the email I'm going to try to send to."
      echo "yikes! 500! Maybe restart mysql... but I'm just guessing" | mail -s "500 error @ '$1'" "'$2'";;
  esac
fi

usage example:

/home/z3cka/isu/isu.sh your-domain-to.check your@e.mail
