Bash: Read Variables from Text-File VAR=VALUE Format

Question

I want to load some variable from a text file into my batch script. I tried searching but I only find tips for files like

VALUE1
VALUE2
...

My TEXT-File has the following format:

VER=123
MIN_VER=123456789
TARGET_VER=132456790

And I want to be able to load this file so that I can access the three variables for matching it against a number in bash. How can I achieve this?

Answered! Thanks!

Save your variables to file like you want (VAR=VAL) and run:

. ./your_file

~~Maybe there will have to be"#!/bin/bash" at the beginning of this file.~~ False

I have no control over the variables file (I try to match a plugin updater script against the version of the firmware image) - But as I call thet from /bin/bash it should work - if you're right - Waah I am stupid^^ It worked - Thx!
