I tried this guys stuff a couple of weeks ago and ran into some problems.
Specifically, I need to 'sed' a large (70MB) file. His 'sed' ran for
several minutes, then errored with a "not enough memory" or some such memory
(I truly don't remember). I dl'd the Cygwin DLL and sed, unzipped them, and
voila', the Cygwin sed ran without a problem (in less time).
I do admit the idea of native NT versions is attractive, especially since I
couldn't get Cygwin's sed to recognize paths (from cmd, not bash),
regardless of how I entered them. I had to put sed in the same directory as
the file to be 'sed'ed, which worked fine. I tried
sed \dir\dir\filename.ext
and
sed /dir/dir/filename.ext
and neither worked (gave "no such file" type of message). I know we're
supposed to be able to run the executables from cmd, but I couldn't find
anything in either the user manual or in the archives (I made an attempt to
search the archives, but I really had no idea on what words to search <g>).

Subject: Re: Horrid Configuration - more data. Help Please
Perhaps you've already considered this, and I
feel...disloyal...mentioning it, but it's possible Cygwin is not the
right platform for your purposes. What about mingw + a suite of
natively-compiled unix-like tools? It's been my experience that you
almost *have* to use a unix shell (bash, tcsh, zsh, etc) with cygwin
tools, or weird problems crop up. It's *possible* to run everything
from command.com, but awkward and will probably cause more problems for
your windows-addicted associates and students than it solves, IMO.
Check out mingw:
http://www.mingw.org/
I can't recommend this suite of tools, 'cause the guy is violating the
GPL -- but if enough people pester him maybe he'll put the source code
up on his site:
http://www.weihenstephan.de/~syring/win32/UnxUtils.html
There are other alternatives that comply with the GPL, however:
