Umm I typed into google "md5 checksum windows", the 2nd result looked
promising so I clicked it, and it seems to offer a free command-line tool
that does exactly what you want. It took like 10 seconds, Linux takes
longer than that to boot.

If you have ever done any windows scripting it should be a piece of cake,
this is pretty standard stuff for dealing with files in scripts:
Set FSO = CreateObject("Scripting.FileSystemObject")
Set Folder = FSO.GetFolder("folder name")
Set Files = Folder.Files
For Each File in Files
do something with File.Name here

Except that the Linux MD5 tool can automatically compute the MD5 sum of
multiple files. I have only found one tool for Windows that can do this,
and it was buggy as hell. (Kept printing garbage characters to stdout,
got confused by certain pathnames, etc.)

The one I found seemed to offer that too.

VBscript, it's what most people use to write scripts on windows, isn't it?

What, wildcards or bugginess? :-}

Actually I just write DOS scripts. If I need anything more complex, I
write Haskell.
As a matter of fact, I wrote an MD5 program in Haskell. But it turns out
not to be very fast...

There's always this: :-)

Hehe, not surprising.

That seems to be a problem with Windows: It simply doesn't invite you
to do things by scripting.
I have been a regular Windows user for over 10 years, yet I don't have
the slightest idea about vbscripts nor even how you could even run them.
Can you run them directly? Do you need some kind of interpreter for it?
Does Windows support them by default, or do you need to install something?
I really don't have the slightest idea. I don't even know where to start.
I have also been a regular Unix user for over 10 years, and I'm somewhat
fluent in shell scripting. I'm in fact so used to it, that I find a terminal
emulator much more comfortable for browsing and handling files than a
graphical file browser (even though all linux distros have both).
I can't say which system I have used more overall, but I think it's
rather telling that in one system I'm pretty fluent with its scripting,
while in the other I don't have the faintest idea where to even start
looking. There is just some fundamental difference in these two systems
which causes different natural way of thinking.

Yeah. Looks like my perfectly working login scripts are going to be
replaced with this at some point. For one reason or another, the guys
from HQ seem to like to do things in the most complex and difficult way
possible. I guess it makes them feel superior or something...

Come back after *you* have implemented MD5 _correctly_. It's nontrivial
to get it to work properly. :-P (There are all kinds of gotchas about
using little-endian integers, doing padding correctly, etc.)

I guess that's because it's "designed for novicies".
On the other hand, just about every tool in MS Office comes with VBA.
It's just that Windows itself doesn't really invite you to script it.

The DOS scripts I usually write work regardless. (*.bat, or *.cmd for NT
or later.) As I understand it, to run exotic languages like VBScript or
JavaScript, you need the Windows Script Host (WSH). This is an optional
extra for NT 4.0, but comes with XP (and, presumably, later). I did have
a look at using JavaScript in this capacity, but I couldn't find any
documentation anywhere.

I find a GUI to be a superior way of *viewing* files (in general), but
the CLI can be a superior way of *working on* files. From a command
prompt, I can easily say "del *.png", but no GUI I've ever seen offers
similar functionallity.
Sometimes I fantasise about writing my own file manager. It's right up
there next to my various other unfinished projects. :-/

And, fwiw, the term "win32" usually gives better hits than "windows" if
you're looking for ports of GNU stuff to native windows.

Or just
for %I in (*.txt) do md5 %I >>checksums.txt
or whatever parameters you want. It's not like Windows doesn't have a shell. :-)

Does that work recursively?
Slightly more fun is trying to make it produce the exact same output as
the Unix MD5 tool so it's portable between OSes... ;-)
