fine, thanks... it is crazy that a simple utility like xxd(1) is missing

Geeze mate, you'll find a lot of other tools missing too. Sed for starters which I find particularly useful.

Windows batch file have traditionally been cobbled together using undocumented techniques (and third party programs) and is the charm in creating batch files.
With NT versions of windows it became a lot easier, but it is still patchwork in many ways. Microsoft made Powershell as a batch replacement - I have yet to do much with it.

Yes but very cumbersome.

binary file from the hex dump? (I did not run the script to see.)
BTW, superpollo's original post seems to have got lost.

Also, googlegroups confirms that foxidrive's post was the first post in
this thread.
http://groups.google.com/group/alt.msdos.batch/browse_thread/thread/4a970d8993ab1c1b#
Maybe it was posted in a different group with follow-up redirected here?

have it. Are you still looking for a solution? One where you provide a
source filespec and an output filespec and optionally provide a reverse
flag?

is a vbscript for Win98+ systems.
'hexdump.vbs
'Usage:
'cscript /nologo hexdump.vbs <infile.ext >hexdump.txt
'cscript /nologo hexdump.vbs -r <hexdump.txt >outfile.ext
'
Dim StdIn, StdOut
Set StdIn = WScript.StdIn
Set StdOut = WScript.StdOut
If WScript.Arguments.Count = 0 Then
Do While Not StdIn.AtEndOfStream
StdOut.Write Right("0"+Hex(Asc(StdIn.Read(1))),2)
n = n + 1
If n = 35 Then
n = 0
StdOut.Write vbCrLf
End If
Loop
ElseIf WScript.Arguments.count = 1 Then
If Lcase(WScript.Arguments(0)) = "-r" Then
Do While Not StdIn.AtEndOfStream
str = StdIn.ReadLine
For i = 1 to Len(str) step 2
StdOut.Write Chr("&H"+Mid(str,i,2))
Next
Loop
End If
End If
Now, you can either use it on command line using the syntax as shown at
the top of the script, or create a batch wrapper to invoke it. This is a
simple batch example without any error trapping. I leave it for you to
improve as deemed necessary.
::hexdump.bat
@echo off
if %1.==-r. goto :reverse
cscript /nologo hexdump.vbs <%1 >%2
goto :eof
::
:reverse
cscript /nologo hexdump.vbs -r <%2 >%3
:eof
