I have a requirement in which I need to replace particular character from a string, by using a DOS command.
For example, if my string is "1,2,3,4", I need to get the result "1.2.3.4" by replacing each "," with a "." character.
Following will work for you
@echo off
set string1=1,2,3,4
set string2=%string1:,=.%
echo %string2%
