ed scripts in Windows command shell

Although I have experience with diff and ed on *nix, I just
can't seem
to get ed to work in the Win32 environment (cmd.exe).

diff -e oldfile newfile > script.ed

gives the proper ed commands, but any variation of

type script.ed | ed oldfile > result

just won't work: I get either an empty result, or the last
line of the
original file repeated a few times in the result. I've tried
'for'
loops with 'echo' and 'type', appending 'w' and 'q' commands
to
script.ed, and all sorts of variations. Still no luck.

Has anyone had success using 'ed' commands with Win32?


P.S. I want to use the 'ed' output from diff, since several
'ed'
commands can be concatenated together to apply several
changes -
unlike 'context' and 'unified' diffs that have to be
appiled
individually against each intermediate result.

P.P.S.

I'm trying to use the GnuWin32 ed utility.

This worked:

ed < script.ed oldfile

Note that script.ed has "w" at the end to tell ed
to write the changes.

If you have multiple ed script files generated by diff, then
concatenate  
all the script files and append "w" into one
script file.  In cmd.exe:

(cat f1 f1 ... && echo w) > script.ed

Don't know GnuWin32's ed doesn't accept input from a pipe.

Thanks for the reply.

Even when script.ed has a "w"  (or "w"
and "q")  appended to it,
oldfile remains unchanged. :-/

script.ed:

78a

    public void noop();
.
w

----

ed < script.ed oldfile

doesn't change oldfile

ed oldfile < script.ed

doesn't change oldfile

I've had success with GnuWin32 'patch', applying incremental
diffs,
but just can't get 'ed' to work.  If not for your 'This
worked", I
would conclude that 'ed' just can't be used this way in a
Win32
environment.

What a puzzle.

Which version of "ed" are you using?  Mine is:

C:Temp>ed --version
GNU ed version 0.2
