Is it possible to get the current temperature to use in a shell script?

Let me explain what I am doing and what I would like to do.

I have a webcam. I use a shell script every five minutes to: 

   1. grab an image with avconv
   2. add text, including 'current' temperature (from a txt file generated 
   using cheetah generator) and the time.
   3. save the image so that rsync uploads it to my website with the other 
   files.

You can see the result here  <http://www.weather.molyvos.eu/image.jpg>

My problem is the txt file is 5 minutes old. There is normally small or no 
difference between 'current' and 5-minute old data. BUT, there are times 
when the difference is significant and I would like to "do better"!

I really am not good at this stuff, I meddle and poke until I get things 
sorted or I break something, normally the latter. So I was hoping that 
somebody could advise me.

Can I use in my script to get loop data so the temperature will be correct 
at the time of the grab?

Thanks, people.
