sed match DOS end of line

sed match DOS end of line

[Steve Harlow]

Greetings,

With 'sed' (GNU sed) version 4.4 I am seeing that '$' doesn't match end 
of line with windows type text files.
It looks like something like this happened and was fixed on version 4.2.2.
https://cygwin.com/ml/cygwin/2013-06/msg00685.html

Here is the original complaint at the time.  I'm seeing the same thing 
with version 4.4.
https://cygwin.com/ml/cygwin/2013-06/msg00673.html

Do I not have some environment variable set correctly? Is this a bug in sed?

I see that I can install the older version, 4.2.2.3.  Looks like that 
might take a step backwards on some libraries too. compiler-rt(5.0.1-1), 
libc++devel (5.0.1-1), libc++1 (5.0.1-1), etc.  Is that the right way to go?

Regards,
Steve

nope - this is documented and has been discuessed at length already - past
behavior was wrong if you were on binary mount and/or pipe. current behavior is
correct for those cases:

This seems to be an upstream change.  The Cygwin 4.2.1 and 4.2.2
releases are build the same way.  4.2.1-2 (-3 on 64 bit) and 4.2.2-1 are
both built from just the vanilla upstream sources.

While 4.2.2-2 adds the latest upstream gnulib regex, it behaves
otherwise identically to 4.2.2-1.  And both 4.2.2 releases show the same
behaviour in terms of CRLF line endings.

But it's really puzzeling.  There's no indication for this change
in the sources.

Since this 'sed' change, I noticed that "$" does not match a dos formatted file end-of-line anymore.

example:
echo "endofline^M" | sed "s/e$/X/"

sed 4.2.1 returns
   endoflinX

sed 4.2.2 returns
   endofline

I don’t know if this is better or worse, or expected or not, but it is easy enough to fix my broken scripts.
Scripts will be less portable between windows and linux now unless I take this into consideration.
(and replace "$" with "^M*$")

$ echo $LANG
