How to read a file with delimitted name value pairs using DOS batch script?

Question

I have a file with each line of the format name=value. I need to read it using a DOS script and store all the name value pairs in memory. The names are from a predefined list of names, so I can have a list of DOS variables, and assign values to them as and when a line is read from the file. Please provide the script for doing this. I'm not able to even do as much as read a file using the below code which I got on the internet, it printes nothing: FOR /F %i IN (regfort.properties) DO @echo %i

Answer 1

This is a very simple script that sets some environment variables (names prefixed with prop_) based on the name/value pairs in the specified file, i.e. name=value in the file becomes prop_name=value in the environment:

setlocal disabledelayedexpansion
FOR /F "tokens=1* delims==" %%i IN (regfort.properties) DO set "prop_%%i=%%j"

Running set prop_ will then display the names and values of all variables with name prefix prop_.
