Only write one number to log file and delete old ones?

Hey,

I'm trying to have some software read from a .text file a number (GPU Temp) but the software will only the first number in a list (Or the first anything)

Is there a way to have to log file delete the previous entries and write the new number in it's place without any headers?


EDIT:

Sorry I'll try again.

I have some webcam software that can read a number (or whatever) from a text file and then it displays the number as an overlay.

See here: http://10.244.193.13:8081/

I was trying to use GPU-z to do this but as it logs as a list the webcam software can't update properly (also it reads the headings of the file and displays them instead)

Is there anyway to alter the logging to only output just the number (GPU Temp) and to delete the old numbers so the new value is the only value in the file.
