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 g_colonna@sympatico.ca 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)

Step 2: Fun Thing # 2

of course, theres the slightly-more-legal-but-still-annoying-fun field of pranking your friends. these work really well of someone who isn't that computer smart. Of course these are all harmless and will cause no damage. The worst thing that could possibly happen is their computer freezes. they restart. its fine. yippee.

Try this:
@echo off
echo You have been infected.
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
echo The virus will now proceed to delete your entire hard drive.....thank you for being patient...
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
msg * press ok to stop the virus
msg * haha i lied. the virus will now continue :D have a nice day.
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
echo deleting.......
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
echo YOU'VE BEEN FOOLED. THERE IS NO VIRUS.
pause

what it looks like:

Step 3: Ah the Evil One.

This one can be especially mean if you screw with it too much.
There are many variations, because its only one line. all you do is type:

shutdown -f -s -c "your message here".

This will shutdown the computer when run, displaying a timer and a message of your choice.
if you accidentally run this program on yourself, go and type shutdown -a in the command prompt. this aborts the forced shutdown.

see the -f -s -c part? those are arguments. you can use those and the ones in the list below in any combination you like.

-s <- this shuts down the computer
-r <- this restarts the computer
-l <- this logs off the user
-f <- this forces all programs running to shutdown
-t <- this is the time limit until shutdown (the time is in seconds so -t 60 means 60 seconds until the shutdown commences )
try not to mix -s and -r and -l, only use one at a time, as i cannot guarantee what happens when you mix them.

Now you're probably like WTF? i don't know how to use this in a batch file.....no ones dumb enough to run it.....

Solution: Create a shortcut on the desktop, and give it a nice icon / name (something a curious friend will open)
In the box where it says location type your shutdown code (the above stuff)
*curious friend opens it* and his computer shuts down :D
another solution
Tha code:

@echo off
echo you've been infected with a fun little virus that will now wipe out your computer.
echo please wait .........
pathping localhost -q 2 -p 250 > nul
pathping localhost -q 2 -p 250 > nul
echo done!
pathping localhost -q 2 -p 250 > nul
shutdown -f

This closes all their programs, making them think thier drives are wiped :P

Step 4: Just a Reminder

AGAIN: SEND ANY IDEAS FOR A NEW BATCH RELATED (hell, any idea is good, even non batch) INSTRUCTABLE AND I WILL PUBLISH IT (batch preferred though, im really good at that and will get done faster). AGAIN, YOUR NAME WILL BE MENTIONED :D

Dead line is august 27nd. no entries accepted on the 28th.

send ideas here with subject line batch idea:

g_colonna@sympatico.ca

thanks for reading!
