Where the heck is the documentation for cmd these days? Searching the
Microsoft knowledgebases and what's available on the web site for any
information about the command interpreter is like looking for WMD.

I need to know in what versions of the command interpreter things were
added. In particular, features under command extensions and the argument
expansion tags (like for /I and %~f0 and %CD%). Is this information
available somewhere?

It's in Help & Support on Start and 99% is in command /?.

Type command prompt overview and follow the links on the page. ~ things are in For's help.

See TheGuardBook, Online Reference for
Cross-Platform Shell Scripting at
(http://TheSystemGuard.com/TheGuardBook/CCS-Int).

All the commands internal to cmd.exe are documented
here in "Mounted Help" pages. This includes a
color-keyed merged help page highlighting the differences
among all internal commands in NT/2K/XP/K3. The
"Common Help" from each OS's help screen is also
available for comparison.

Exactly where in there is any version information at all?

Thanks anyway,
Greg

Umm, are you saying I should install every version of Windows and retrieve
the help files for cmd and command under each of them and compare those to
see what was implemented when?

I was rather hoping for something a little less brute-force.

Greg

You read each help file.
 
Thank you. It looks like some of the info is still being assembled, but
this is very useful. Way better than what I had before - which was nothing!

One thing I am not finding there is what was implemented in the different
versions of command extensions. Windows XP returns 2 for %CMDEXTVERSION%,
so I am assuming something was added. Would you happen to know anything
about this?

Thanks again,
Greg

You're welcomed.

Version 2 of the Command Extensions was implemented in Windows 2000. This
version also applies to XP and Server 2003. Several commands have
additional or changed options when extensions are enabled.

A list of the changed commands is on the "Cmd Page"
under "Examples, Notes and Instructions". See
(http://TheSystemGuard.com/TheGuardBook/CCS-Ext/Cmd.htm)

Click a command from the list to go to it's page.

Pay particular attention to the color backgrounds
to see the syntax that applies to Windows 2000
and above.
