Question

I am trying to replace all instances of a character in a string of text with another character but I’m not succeeding.

Suppose the text is

cat rat mat fat

I want the script to replace all the t's to p's

cap rap map fap

What I have is the following but it seems to do little for me.

SET /P MY_TEXT=ENTER TEXT:

SET T2P=P

SET NEW_TEXT=%TEXT=:T!T2P!%

MSG * %NEW_TEXT%

Answer 1

You’ve got the = sign in the wrong place. Try:

setlocal enabledelayedexpansion
set /P MY_TEXT=ENTER TEXT:
SET T2P=P
set NEW_TEXT=%MY_TEXT:T=!T2P!%
MSG * %NEW_TEXT%

You can also do the expansion the other way round, i.e.

set NEW_TEXT=!MY_TEXT:T=%T2P%!
