GNU/Linux BASH website probe using CURL

Small script I used to probe a website. Script should returns a message only when the state changes.

#!/bin/bash

function funcProbe {
  curl ${1} -k -I -s | grep "HTTP/1.1 200 OK" > /dev/null
  if [ $? -ne 0 ]; then
    if [ ! -f /tmp/prb-${2}-DOWN ]; then
      echo "[S2:Probe-${2}] Service DOWN Detected!"
    fi
    touch /tmp/prb-${2}-DOWN
    rm -f /tmp/prb-${2}-UP
  else
    if [ ! -f /tmp/prb-${2}-UP ]; then
      echo "[S2:Probe-${2}] Service UP Detected!"
    fi
    touch /tmp/prb-${2}-UP
    rm -f /tmp/prb-${2}-DOWN
  fi
}
