Batch file; Replace variable's spaces with hyphens

Question

I've started another small Batch project, however I've encountered a bit of a dilemma. I use set name= followed by set /p name=, to allow the user to give the input desired. However, I want the variable entered with spaces to then have the spaces replaced with hyphens (e.g. "hello world" becomes "hello-world").

I've searched around and found many situations in which someone asks a similar question, however they are all using the ren command, which I have no use for due to not dealing with files.

My current code is as follows:

@echo off
Cls
echo Insert a string with spaces?
set string=
set /p string=

I have also found a solution for renaming files that mentioned using ren "!file!" "!file:_= !" to change a file name's spaces to underscores (_). However changing it to set name=!name:-= ! didn't work for me.

How can I best replace spaces with hyphens in my batch file?

Solution

You're close.

@echo off
cls
echo Insert a string with spaces?
set string=
set /p string=
set string=%string: =-%
echo String is now %string%

See set /? for details on variable manipulation.

Thanks, works like a charm. Also, I now see how setting a variable works, after the :, instead of acting off a guess. Thanks again!
