Windows batch files. (yay)

I want a variable which contains all command line arguments except the first two, preferably prefixed with a hyphen.

I can achieve that like this:
code:
ECHO %* | sed -e 's/%1 %2/ -/'

(I've got a sed.exe for Windows on my path)

However, I can't figure out how to put that into a variable which I can make use of in further commands?

The SET command doesn't allow piping, and only evaluates numeric expressions.

Any ideas?

Hmmm, so the SHIFT command allows you to remove the first command and shift the others all left one.

However, it looks like it affects the numbered %0 %1 %2 variables, and doesn't appear to %*, so this doesn't work:
code:
SHIFT
SHIFT
SET myvar=%*


:(

I will repeat Rendle's advice to you in the past- learn C#, you'll have a console application up and running in two minutes.

I don't have .NET installed on this machine, and don't want to have to always compile the script as I adapt it.

If I can't do this with BAT then I'll switch to WPF, which will let me use JavaScript.

Ah, one of our Network Services guys was talking about that a while ago ...and then he ran away to the Netherlands before telling me about it more. :(

Do you have any good overview tutorial links to hand?

(And is it worth getting the 2.0 CTP, or is 1.0 good enough?)
1.0 has stupid Windows Genuine Advantage crap. 2.0 CTP doesn't, so I've gone with that.

Why does it take THREE SECONDS for PowerShell to actually start? :|

Three seconds for a shell is not quick.

I found some pages related to running an ngen command, and it has cut the time to around 0.8 seconds, but that's still far too slow.

CMD and BAT files are almost instant.


Update...
I just created the following:
code:
ECHO %TIME% before PS
%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe weee.ps1
ECHO %TIME% after PS
 
ECHO %TIME% before BAT
CALL weee.bat
ECHO %TIME% after BAT
 
ECHO %TIME% before BAT2
START /WAIT weee2.bat
ECHO %TIME% after BAT2


(the weee.ps1 and weee.bat both contain ECHO "Weee" the weee2.bat also contains an EXIT command.)

PS takes between 75ms and 85ms to run every time.

First BAT runs with no time difference at all (doesn't wait?).

Second BAT runs on average in 6ms (varies from 4ms to 7ms)

Because it's an insanely powerful object-oriented scripting environment, not an OS command line.

If I wanted an insanely powerful object-oriented scripting environment, I'd use C#Java.

You obviously do want one, cos you're trying to pipe to a variable. Btw, does the 2.0 CTP have Linq support?

It does if you've got .NET 3.5 installed.

Doesn't require 3.5 to use other stuff though.
