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 😉

Iphone/Ipad number format css style change in safari

Here's something interesting yet simple to share for a long time. If you are wondering and debugging countless hours for a very simple thing such as color change on a number format in ipad or iphone, you might just arrived to the correct blog post. We all know that debugging CSS and HTML in ipad or iphone isn't an easy task although we can emulate the environment, there are certain things we cannot emulate such as the behavior of the ipad or iphone OS itself. Interestingly, a client of mine faced such issue with their website where his 'contact' number listed on his website was changed to blue instead of white as declared on the css file when view on ipad or iphone.

Now, the odd thing is that even the emulator is showing the colors correctly. Debugged for a few hours without any luck but notice that whenever i added alphabet into the numbers, it changes back to the correct colors. I though it was some javascript but it wasn't. In the end, i disabled the whole CSS and notice something different on the emulator and the ipad. Weirdly, ipad and iphone treat numbers as a link because it can be a contact on safari. Therefore, it automatically wrapped around a group of numbers with an anchor link on a web page. Therefore, your CSS declaration have to write something like

.style{
color: blue
}

and added something like

.style, .style a{
color: blue
}

if you wish to cater to ipad or iphone on your website. Even if you do not have a mobile stylesheet, ipad or iphone will still behave this way. Therefore, for any group of numbers on your website, just take note of such behavior on mobile devices such as iphone or ipad.

“You do not have sufficient permissions to access this page.” Unable to access WordPress

Well, if you are unable to access your WordPress installation and received the message "You do not have sufficient permissions to access this page.", it is most likely that your WordPress installation, upgrading or migration has been screwed and the access of your user has all been lifted. In order to restore all these, you will need a bit of work to get it started again. However, there are still temporary solutions which you can undertake to make it work which doesn't completely solve your problem but temporary allow you to access WordPress. Just managed to get it working for a client so for all others who are seeking for a solutions as well, hope the tips help. Good Luck 🙂

Firefox is really good web development tool for both web developer and designer for many years.
