Shifts the batch file arguments along, but does not affect %. Thus, if %1=Hello 1, %2=Hello 2, and %3=Hello 3, then, after SHIFT, %1=Hello 2, and %2=Hello 3, but % is "Hello 1" "Hello 2" "Hello 3".

$ shift /?
Changes the position of replaceable parameters in a batch file.

SHIFT [/n]

If Command Extensions are enabled the SHIFT command supports
the /n switch which tells the command to start shifting at the
nth argument, where n may be between zero and eight.  For example:

    SHIFT /2

would shift %3 to %2, %4 to %3, etc. and leave %0 and %1 unaffected.
