Batch Script - Replace a String


Advertisements

To replace a substring with another string use the string substitution feature.

Example

@echo off 
set str=This message needs changed. 
echo %str% 

set str=%str:needs=has% 
echo %str%

The key thing to note about the above program is, the example replaces the word ‘needs’ with the string ‘has’ via the statement %str:needs = has%

Output

The above command produces the following output.

This message needs changed. 
This message has changed.
