SHIFT [/n]
If Command Extensions are enabled the SHIFT command supports the /n switch that 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.
Examples
The below example would be done in a batch file; in this example we are naming the batch file test.bat and it contains the below lines.
@ECHO OFF
ECHO - %1
SHIFT
ECHO - %1
After creating the above example test.bat file, if you were to type the below command at the MS-DOS prompt, it would print "- ONE" and then "- TWO"; this command is commonly used to work through each of the command extensions or remove command extensions.
TEST ONE TWO
