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.
