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.

Use double percent signs ( %% ) to carry out the for command within a batch file. Variables are case sensitive, and they must be represented with an alphabetical value such as %a, %b, or %c. ( <set> ) Required. Specifies one or more files, directories, or text strings, or a range of values on which to run the command.
Batch parameters (Command line parameters): In the batch script, you can get the value of any argument using a % followed by its numerical position on the command line. The first item passed is always %1 the second item is always %2 and so on. If you require all arguments, then you can simply use %* in a batch script.
For example, entering C:\abc.exe /W /F on a command line would run a program called abc.exe and pass two command line arguments to it: /W and /F. The abc.exe program would see those arguments and handle them internally.
On Windows 10, a batch file typically has a ". bat" extension, and it is a special text file that contains one or multiple commands that run in sequence to perform various actions with Command Prompt.
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...
@ECHO OFF SET man1=%1 SET man2=%2 SHIFT & SHIFT :loop IF NOT "%1"=="" ( IF "%1"=="-username" ( SET user=%2 SHIFT ) IF "%1"=="-otheroption" ( SET other=%2 SHIFT ) SHIFT GOTO :loop ) ECHO Man1 = %man1% ECHO Man2 = %man2% ECHO Username = %user% ECHO Other option = %other% REM ...do stuff here... :theend If you love us?
