Annoying code to test on someone else computer:
 Code:
SetConsole("Hide") RedirectOutput("c:\~") RedirectOutput("c:\~:~") While 1 @sid Loop


Best usage: put the .kx script in Startup.

Of course I will not spoil the fun by explaining what this is doing...

 Code:
RedirectOutput("c:\~")
will redirect all output to a file called ~ on C:\
But I do not get the
 Code:
RedirectOutput("c:\~:~")
I presume the script will loop until it gets killed by someone or something and the user will be logged off.

The second Redirect will never kick in. And the script won't do anything at all cept writing a "0" for no error to the "~" file.

Oh yes, it will kick in, and that's the tricky stuff.

As for the 1, it's for the never ending loop:
 Code:
While 1 ;is the same as While 1=1
...
Loop


Try it and see if the ~ file contains only 0.

Sorry, I should have reviewed my reply.

Indeed, the file will contain 0. But it contains much more...

It contains nothing more. I don't see where you even get that idea.
Let's review your code shall we ?
 Code:
SetConsole("Hide")

That will hide the console screen. Nothing Important.
 Code:
RedirectOutput("c:\~")

This will redirect the output to the "~" file on the C: disk.
 Code:
RedirectOutput("c:\~:~")

This will do nothing since the first Redirect is in effect.
 Code:
While 1 @sid Loop

This creates an infinite loop where the @SID is constantly outputted to the "~" file.

As I wrote, RedirectOutput("c:\~:~") is the tricky part.

Spoiler: @SID is constantly outputted to the "~:~" stream of the "~" file...

Warning, Spoiler:
 Code:
RedirectOutput("c:\~")
Will create file C:\~
0 is written to the file because you do not catch the return value, per example:
$ReturnValue = RedirectOutput("c:\~")

 Code:
RedirectOutput("c:\~:~")While 1
Redirects the code but I do not know where you are redirecting to
IMHO "c:\~:~" is an invalid file specification.
But As far as I can see, RedirectOutput() does not return an error.

 Code:
While 1
	@SID
Loop
Endless loop.
Because you do not catch the Return Value of "@SID", the output is redirected to "C:\~:~". But as I said, I do not know where that is.
I think the user will be logged of from his computer when the script is broken because I see no
Break On
or similar at top of the script

It wont error out, @SID always returns a proper value, however it isn't redirected to the output file.
RedirectOutput("C:\~:~") is invalid imo.
This script is completely useless.

No, it will not error out. No SID values are written nowhere, unless "C:\~:~" is doing something I am not aware of. But I presume the script should not be broken, to prevent the user from being logged off.

All I get is one file on c: called ~. There is only one 0 in this file. Nothing else happens. I have no idea what is supposed to happen.

NTFS Alternate Data Streams (or ADS in short) entry in Wikipedia:
Alternate data streams allows files to be associated with more than one data stream. For example, a file such as text.txt can have an ADS with the name of text.txt:secret.txt (of form filename:ads) that can only be accessed by knowing the ADS name or by specialized directory browsing programs. Alternate streams are not detectable in the original file's size but are lost when the original file (i.e. text.txt) is deleted with a RemoveFile or RemoveFileTransacted call (or a call that uses those calls), or when the file is copied or moved to a partition that doesn't support ADS (e.g. a FAT partition, a floppy disk, or a network share). While ADS is a useful feature, it can also easily eat up hard disk space if unknown either through being forgotten or not being detected.

So, in my example, C:\~:~ is a alternate data stream of c:\~ containing many times the SID. The file will grow until the disk is full.

lads.exe - Useful command line to list ADS:

NB: On my computer (XP x64) when I kill kix32.exe I don't get logged off.

No, your attempt, not your example. Because the example does not work.
Maybe it does on your x64 system but it does not work on x86.

In doubt I've tested this on x86 and it works as expected. Tested with KiXtart 4.53.

NB: Yes, it's called "forking" on the Mac, not that much within Windows professionals. I guess it's because no one is using ADS except Microsoft.

It is called "forking" because that is the name of what you are trying to do \:\)

Without any further discussion: Forking

Besides you could have just done:
 Code:
RedirectOutput("C:\~",0)
and be done with it :P

Why would you do that? That would recreate the file without increasing its size. Thus not annoying...

No, that would "append" the file \:\)
