cmd scripting

[Guest]

Hello,

I made a batch (.bat) file. That batch file includes:

echo hello > file.txt

There is a problem when running that batch file. When I run batch file in
cmd window, it runs and I see:

echo hello 1> file.txt

command line. But I didn't write that line in the batch file.


Why does it run like that? I have to write important batch file and it must
be a flawless.

Thanks...

1> and > mean the same here, both referring to standard output.

If it's the line repeating itself that bugs you, then you could add
@echo off
at the top of your batch file to stop the echo.

It's not important for me.

Thanks Jon.

Perhaps someone else will chip in with an authorative documentation source.
Here's another site that says the same
http://www.robvanderwoude.com/index.html

You could easily confirm it yourself, by changing your batch file line
echo hello > file.txt
to
echo hello 1> file.txt

and observing that they do the same

Hi,

In WinXP's Help and Support Center, search for "redirection operators"...
