Looking for Unix style 'getopt' command li

Question

Can anyone help me find something to parse command line args in a Windows batch file like one would do in a Unix shell script using getopt/getopts? It doesn't have to be all Posix-y; just something that I can specify what switches I expect, which of them require/allow an argument. They don't need to be "long" switches; single characters will work.

It can be an external .exe that the batch file calls. It has to be freely distributable.

Answer 1

You can you something like this (-h has no args, hence no shift after that, -b and -s take additional args, so shift them).

:GETOPTS
 if /I "%1" == "-h" goto Help
 if /I "%1" == "-b" set BASE=%2 & shift
 if /I "%1" == "-s" set SQL=%2 & shift
 shift
if not "%1" == "" goto GETOPTS

Answer 2

There is no such thing as getopt/getopts-like parsing of commandline arguments as you know from Unix/Linux.

Batch files only know about %0, %1, %2, ... and %* (and such variations as %~0, %~1... which remove quotes, should there be ones around an arg).

Up to nine arguments. If there are more to process, you can use shift (equiv. to shift /1 if enableextensions happened) to remove the first arg and shift the rest.

Basically that's it.
