Another noob question

I was on metacafe watching all the video Tutorials I could on hacking and what Really struck my interest was the .bat files and different things you could do with command prompt such as turn your CMD to a instant messenger. Could anyone please give me some insight on this? or what I would need to read to learn for myself?

here is the code just in case anyone was curious

@echo off
:A
echo Messenger
set/p n=User/IP:
set/p M=Message:
net send %n% %m%
pause
goto A

Just copy and paste into notepad and save as .bat file
and for it to work you need the name or IP address of the computer you would like to speak with....

Net send is a windows messaging client; most people disable it as it's quite annoying and pointless...

Your bat script is basically reading in what a user sends and formats it, then displays it for you... It's quite basic and will only work where net send isn't disabled (and to where it isn't disabled)

There is a semi decent "What Is NetSend" article here the writer doesn't seem to have a firm grasp over the English Language, so you may re-read several paragraphs several times...

Cool thanks Gizmo.
