Is there a list or anything? I know of %allusersprofile% (location of all
users folder), %computername%, %systemroot%, %username%, %os%...does anyone
know all of them?

at <hh>:<mm+2> /inter cmd /k set

By the way: %username% isn't a system but user variable.

Ah. I thought it stood for "Multiple Choice Selection Expert."

Training? Or do you mean test-taking? :-)

I like the acronym. I don't want to start a flame war here, but I will
admit my ignorance, there is no excuse for that. Being a MCSE for as long
as I have, I should have known that. I appreciate your answer. But part of
being a good computer tech is knowing when to put aside pride and do what it
takes to solve a problem.

Ask me a SQL 4.2/6.5/7.0/2k question, a VB script question sometime or a
different question. I'll get you an answer.

Cheers,
Andy S.

Thanks, I appreciate all the help here, especially for such an obvious
question.

Bill, that isn't all of them. Maybe an MCSE can help you out a little
bit. ; )

%CD% - expands to the current directory string.

%DATE% - expands to current date using same format as DATE command.

%TIME% - expands to current time using same format as TIME command.

%RANDOM% - expands to a random decimal number between 0 and 32767.

%ERRORLEVEL% - expands to the current ERRORLEVEL value

%CMDEXTVERSION% - expands to the current Command Processor Extensions
version number.

%CMDCMDLINE% - expands to the original command line that invoked the
Command Processor.

Not all listed above are system variables but some are. The link
Ritchie posted was the best source of information for this question.
But one can do "Set /?" as well as "Set" from the prompt to get most,
and often all, of these variables.

It is unfortunate that MS doesn't, or at least hasn't, tested
command-line knowledge. If it was up to me, two-thirds of the server
test would be on scripts and CMD prompt tools that come with the OS
and the ResKit. Nothing third-party.

And that spells this time: more competent scripting expertise ? ;-)

Yeah, seems to me the writers of the standard MS courses were more
interested in the flashy GUI interfaces than in the real workhorses.

Good answer, and LOL to boot. But don't tell me you picked up your
reasonable approach to problemsolving and your greater concern for learning
than seeming to look smart from a Microsoft course?

Of that I have no doubt.

Hi Clay,

In my own defense, I might just point out that those are really cmd.exe
"pseudo variables"...

As a simple example, suppose you run this VBScript:

Set objWshShell = CreateObject("Wscript.Shell")
Wscript.Echo objWshShell.Environment("PROCESS")("DATE")

The Echo method will print a blank line.

But yes, you're right, the SET command doesn't list the pseudo-variables.

Regards,

Bill

The proper term is "dynamic variables".

OK. I just called them "pseudo variables" because they're, well, not really
environment variables, but cmd.exe expands them. I'll try to use the right
term from now on. :-)

Regards,

Bill
