Average website response time bash script

Ok i make a little bash script to test a particular website response time. This is done via the command line through a bash script. Anyway, here's the script code.


#!/bin/bash

CURL="/usr/bin/curl"
echo -n "Please pass the url you want to measure: "
read url
URL="$url"
count=1;
total_connect=0
total_start=0 
total_time=0
	echo " Time_Connect Time_startTransfer Time_total ";
while [ $count -le 100 ]
do
	result=`$CURL -o /dev/null -s -w %{time_connect}:%{time_starttransfer}:%{time_total} $URL`
	echo $result;

	var=$(echo $result | awk -F":" '{print $1, $2, $3}')
	set -- $var

	total_connect=`echo "scale=2; $total_connect + $1"  | bc`;
	total_start=`echo "scale=2; $total_start + $2" | bc`;
	total_time=`echo "scale=2; $total_time + $3" | bc`;
	count=$((count+1))
done
echo "average time connect: `echo "scale=2; $total_connect/100" | bc`";
echo "average time start: `echo "scale=2; $total_start/100" | bc`";
echo "average time taken: `echo "scale=2; $total_time/100" | bc`";

What the above does is to prompt you for a url to test and run it for 100 times on your machine and print out the average response time from the website server to your machine.

Assuming you save the above file in 'shell', you will call the above script via 'bash ./shell' and it will prompt you for an url and start executing the url for 100 times and gives you an average response time.

P.S: the above script required you to install bc, you can install via yum install bc or sudo apt-get install bc 😉
