Need bash shell script for reading name value pairs from a file

Question

I have a file like

name1=value1
name2=value2

I need to read this file using shell script and set variables

$name1=value1
$n         


        

Answer 1

If all lines in the input file are of this format, then simply sourcing it will set the variables:

source nameOfFileWithKeyValuePairs

or

. nameOfFileWithKeyValuePairs
