Question

How do i ensure 2 arguments are passed in a bat file?

I would like to echo a description of the arguments and exit the bat if there are not exactly 2 arguments.

Answer 1

See Note 1 on this page about the need for a dummy when testing for empty strings.

IF dummy-==dummy-%1 (
    ECHO Syntax is blah blah
    EXIT /B
)

IF dummy-==dummy-%2 (
    ECHO Syntax is blah blah
    EXIT /B
)

Also I find this is a good reference when writing batch files.
