As has already been stated it is the command prompt.  It doesn't understand the
single-quote ' character as a quoting character.  You could try replacing it
with a double-quote " character; but, I have no idea if it will work.  Most
users of Cygwin use it from the bash prompt so there aren't these kinds of
problems.

You could have make create the foo.sed file.

Actually, if this is being called in a Makefile then setting MAKE_MODE=unix
should fix the problem.

Hola~

This is what I'm doing currently. The sed expression is in a Makefile, so
the better solutution would be to leave it there as opposed to adding a two
line file. I'm not trying to be picky, I just want to understand who's
having problems (sed or the command prompt).

Which is kinda what I was driving at.

The snapshots do understand apostrophe as the quote character, FWIW.

This is a command prompt (not bash) issue, I believe.  The Windows
command prompt does not use the single quote (apostrophe) for quoting,
only double quotes.  The single quotes are probably being passed in to
sed.

I'd suggest to Michael that you try first starting the bash shell, then
run the sed command and see what happens.

I don't believe that B20.1 understands the "'" (apostrophe) quote
character.

odd sed behavior

[Michael O'Brien]

Hola~

When using the 20.1 version of cygwin, I'm seeing the following
strange-ness. From the command prompt:

    F:\>sort  -u  a.msg  |  sed 's/[\\"]/\\&/g;s/.*/\"&\",/'
    sed: -e expression #1, char 21: Unterminated `s' command
    The system cannot find the path specified.

    F:\>sort  -u  a.msg  |  sed 's/[\\"]/\\&/g;s/.*/&,/'

Removing the " from the second s// command to sed, the thing works. I've
tried nearly every way I can think of to escape the " (""", \", \\", '"',
etc). I can't figure out a way that works.

    F:\>sort  -u  a.msg  |  sed 's/.*/\"&\",/'

Removed the first s// from the sed command, the thing works.

    F:\>sort  -u  a.msg  | sed 's/[\\"]/\\&/g'

Removing the second s// command, the thing works.

    F:\>sort  -u  a.msg  |  sed 's/[\\"]/\\&/g' | sed 's/.*/\"&\",/'
    sed: can't read |: No such file or directory
    sed: can't read sed: No such file or directory
    sed: can't read s/.*/\": No such file or directory
    The system cannot find the path specified.

Split the two sed commands up.

Anyone have any ideas why this doesn't work?
