the help doesnt have much on the shift command….it explains the use, but not really how to use it.

anyone know the syntax?

Simple:

shift

that's it!

all it does is pop off the left-most arg on the script's argument list, and reassign $arg1, $arg2, and so on.

In case…

the following script executed as source myShiftScript.cmd A B C D


for i = 1 to 4
shift
echo $arg0
end


will give the following
A
B
C
D
to clear the help example.

thanks….
i guess the syntax for that one is as simple as Antoine said….shift

Yep. What's missing from the implementation is the “shifting” of an arbitrary variable name, e.g.


shift foobar


which would let you have word lists that you could reduce one arg at a time. For that matter, it would be cleaner to match Perl's operators, shift, unshift, push, pop, and splice. But oh well…
