John,

A question: are you interested in learning about how to accomplish these
things in plain old ordinary batch, or are you interested in any solution
that works (like the mount commands might), regardless of the additional
learning curve plus having to download a third party tool such as that being
touted by Mr. "guard"?

If the former, then consider this:

@echo on
outputfile.txt dir "C:\program files"
Click to expand...

When you run the above commands in a batch file, there should be no output
displayed in the command prompt window, and ONLY the output of the two
sample DIR commands will appear in the output file.

Some explanation: ">outputfile.txt" causes the output from the command given
to replace the previous content of the .txt file. ">>outputfile.txt" causes
the output to be appended to the end of the previous content of the .txt
file. In either case, if the .txt file had not previously existed, it will
be created.

If that is insufficient to answer your question, please provide more detail
as to exactly your situation.

Read the other responses as they gave the details but note the
following

If you want EVERYTHING from the batch to go to a "log file"
then you must do the redirection (> log.txt) from OUTSIDE
the batch file on the invocation command, e.g.,

mybatch.cmd >log.txt

AND you must be running a recent OS since earlier ones
didn't support this (e.g., Win2000+, not sure about WinNT 4.0)

OR in the batch file (works for most OSs) you must redirect EACH
command.

Also useful is the ability to get the "Standard Error" either into the log
or disposed of to the "nul" device. The following work on NT and
Win2000+ at least:

(This one is very picky about order of the redirects):

mycommand >logfile.txt 2>&1

or (not so picky)

mycommand >logfile.txt 2>nul

The first one sends "standard output" to the file (can also be written
as 1>logfile.txt but that isn't necessary) and then it also sends "2"
or "Standard Error" to wherever "1-Standard Output" is going.

The second just discards "standard error" to the "nul" (nothing)
device.
 
Of course, consider this:

@echo off
echo C:\program files >outputfile.txt dir
echo C:\documents and settings >>outputfile.txt dir

Does exactly the same thing. :-)
 
Of course, consider this:

@echo off
echo C:\program files >outputfile.txt dir
echo C:\documents and settings >>outputfile.txt dir

In fact, that is the more common usage. I do it the other way around for two
reasons:

a) as a reminder that the command being executed is not what is processing
the redirection, that job belongs to the command pre-processor of cmd.exe.

b) to make it easy to verify that the filename is consistently correct.
consider these two examples, and let me know in which the error is most
apparent:
output.txt echo.short line
Click to expand...

echo.short line >output.txt
echo.a much lengthier line, or so I consider it >>output.txt
echo.average length line >>output.txt
echo.a much lengthier line, or so I think >>output.txt
echo.short line >output.txt
echo.a much lengthier line, or so I consider it to be... >>output.txt
