how to start a 64 bit program from within a bat file on a win 7 64 bit ?

[Asger Joergensen]

Hi

I just tried this in a bat file:


"E:\ZZZZ\Pakket Software\PNG\pngcrush_1_7_42_w64.exe" -v

pause


but the system tells me that pngcrush_1_7_42_w64.exe is not
a valid 32 bit program

I can start the program on the command prompt if I do it manually
by first starting C:\WINDOWS\system32\cmd.exe

How can I get the right 64bit cmd.exe for my bat file ?

I have tried making a shortcut:
C:\WINDOWS\system32\cmd.exe batfilename.bat

but that doesn't work either

Thanks in advance
Best regards
Asger-P

My first guess is to edit the batch file so the invocation reads

cmd.exe /C "E:\ZZZZ\Pakket Software\PNG\pngcrush_1_7_42_w64.exe" -v

I'm a bit rusty on cmd, so I can't promise that the above is correct,
particularly the switch /C.

Hi Gene

Thanks for you answer.
As it turns out there was nothing wrong, except when I copied the exe file,
only the name was copied, so the exe file was empty.

Sorry for the trouble.

Detailed information on switches can be had by running "cmd /?"
The response is several pages, so it is best to redirect to a file and
put it somewhere for future reference.

No trouble.

Actually, that is an entertaining error. I have done similar things also

Of course. Although I actually used "help cmd".

The problem wasn't finding the switches, the problem was not being sure
the switch would do what I thought it would, which the description
didn't clarify for me. Like: would control return to the batch file as
soon as the program started, or would it wait until the program had
completed...

But then, take a look at what Asger Joergensen posted

CMD /? /P

And what, pray tell, does "/P" do, in your opinion?

I find that anything I put on the line after "cmd /?" is ignored, even
if I omit the space after the "?".

Usually it means page by page, but since cmd.exe /? already does that
there is really no deed.

Hi Gene

Since "cmd /?" automatically pages anyway (implicitly using "more"), I
really wanted to know what 'Bob I' thought it meant, not what you
thought it meant, in case it was something else, something new to me.

I already knew (probably for decades now) that "cmd /?" implicitly works
like more.

BTW, paging in the command window might not be the greatest way to look
at a huge file. You *can* scroll up & down, and even search for text,
but searching is not totally convenient...

Had it in my head from somewhere in the past it meant "pages", quick
test showed expected output. You are correct.

Thanks for the reply.

Actually, I have no recollection of that flag, but that's my limitation,
not yours

On looking at my remark before, it does seem a bit snappish.
Apologies...

But in the discussion, I managed to remind myself of more, which can
work either as a command (more stuff.txt) or as a pipe (copy stuff.txt |
more) - similar to Unix.

Accepted, you could have said "WTF you talking about!?!" ;-).

Yep there is a lot of stuff that still works and some that has gone by
the wayside or wasn't documented, the part that I find the most odd is
the relative lack of knowledge about "F1" key!
