What is the convention for Command Prompt window arguments

[academic]

What is the convention for Command Window arguments?

If I write a program called QQQ that takes one argument should I expect a
user to type:

QQQ arg
QQQ -arg
QQQ /arg

or what?


That is, what is the natural thing for Windows users to expect a program to
looks for?


Thanks

Personal preference? While little command line utilities have their place,

Those of us who grew up on operating systems from DEC see

QQQ /opt1 /opt2 ... /optM filename1, filename2 ... filenameN

as "natural" while those with a 'nix background probably prefer

QQQ -opt1 -opt2 ... -optM filename1, filename2 ... filenameN

and for them it is not unusual (I think) to see intervening white space
between the "-" and the option.

I'd suggest that you allow both forms.

Thanks, Windows doesn't have it's own convention? Like maybe none of the
above?

Is VMS still alive?
I always like the user interface of VMS

Well, I don't know that it is written in stone anywhere, but the notation
using slashes (/) is more common than the one with dashes (-).

Take the dir command for example. If you type

dir /ah

you'll get a listing of files with the hidden attribute. If you type

dir -ah

you'll get a "File not found" message.

DEC crashed and burned.

I think that there may still be something called OpenVMS around but I know
nothing about it. You may want to try googling for it.

Well, you can't go wrong with an o/s designed by David Cutler. IMO, his have
been the best there is since the 70s - RSX 11/M, VAX/VMS, Windows NT.

/ is indeed more common for win cmd utilities. another universal option is
/? which prints out the listing of all possible options with a bit of
information.

I wanted to give it a try, but apparently it only runs on true 64 bit
platforms like itanium and alpha. slightly out of budget for me...
I used openvms once in a GPS simulation system, where the VMS machine was
used for maintaining a model of a sattelite constellation in real-time. it
was rock solid. you could throw any abuse at it, and it would keep going.
I remember it had very long command names.

I agree. the linux driver model cannot even begin to compare with the NT
based models.

I think your earlier suggestion to check both makes sense
thanks
