[batch-file] Windows Bat file optional argument parsing

I need my bat file to accept multiple optional named arguments.

mycmd.bat man1 man2 -username alice -otheroption

For example my command has 2 mandatory parameters, and two optional parameters (-username) that has an argument value of alice, and -otheroption:

I'd like to be able to pluck these values into variables.

Just putting out a call to anyone that has already solved this. Man these bat files are a pain.

The answer is

Though I tend to agree with @AlekDavis' comment, there are nonetheless several ways to do this in the NT shell.

The approach I would take advantage of the SHIFT command and IF conditional branching, something like this...


SET man1=%1
SET man2=%2

IF NOT "%1"=="" (
    IF "%1"=="-username" (
        SET user=%2
    IF "%1"=="-otheroption" (
        SET other=%2
    GOTO :loop

ECHO Man1 = %man1%
ECHO Man2 = %man2%
ECHO Username = %user%
ECHO Other option = %other%

REM ...do stuff here...
