Trim output in command prompt

Question

UPDATE: THE PROBLEM IS SOLVED. :)

I want to trim a variable value in windows command prompt.

I used--

set str=sourav
echo %str:~0,3%

as mentioned on an online tutorial.

output-- sou

Can someone explain how this works? I mean how the colon and ~ are working here?

In a cmd prompt type `set /?` and read the help. It is explained in there. — foxidrive, Sep 27 '14 at 14:55
i know how set works... i am talking about the second line echo %str:~0,3% — Sourav Ghosh, Sep 27 '14 at 15:56
