Hello Jason,

which application/game needs this and breaks because it's not present?
Please provide download links.
Thanks.

Regards

Hiya - None, sorry lost track of this. I raised it when I was doing all the
cmd.exe work, trying to get things as complete as I could. This can be closed
if necessary (although is also not too difficult to implement either)

Hello Jason,

I found some information here:

https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en...

--- quote ---
...

%cmdcmdline% expands into the original command line passed to Cmd.exe prior to
any processing by Cmd.exe, provided that there is not already an environment
variable with the name cmdcmdline, in which case you get the cmdcmdline value
instead.

%cmdextversion% expands into the a string representation of the current value
of cmdextversion, provided that there is not already an environment variable
with the name CMDEXTVERSION, in which case you get the CMDEXTVERSION value
instead.

...
--- quote ----

Also here: http://www.robvanderwoude.com/ntif.php

This forum has some example code/snippets:
http://ss64.org/viewtopic.php?id=1834

An interesting remark here:

--- quote ---
Distinguishing NT4 from 2k and later with command extensions enabled is simply
a matter of doing if CmdExtVersion 2 ... check or checking whether
CMDEXTVERSION environment variable is dynamic (like in the above example)...
and there is no real difference with command extensions disabled. AFAIK, there
have been no significant changes to cmd.exe since Win2k and, since MS has all
but abandoned development of CMD shell in favor of PowerShell, it is unlikely
that we'll ever see any new internal commands or major changes to existing
ones. As for detecting availability of external commands, you just try to run
the command and do if ErrorLevel 9009 ... check afterward.
--- quote ---

Suggesting the extensions would be of limited value as MS pushes for
PowerShell.

If you don't mind I'd remove '%HIGHESTNUMANODENUMBER%' from the list (since it
applies to a very limited use-case) and we treat '%CMDEXTVERSION%' and
'%CMDCMDLINE%' as enhancement, lowering severity.

Thanks.

One user of cmdcmdline is ghidra's startup batch file, trying to distinguish
if started via doubleclick or from command line:

https://github.com/NationalSecurityAgency/ghidra/blob/184180d54dbdf3db3c030e...

However, startup does not break because of this missing variable.
