The command works fine for me.
On my AIX box with KSH :
Code:
gssjgu:/g/g00k00/gssjgu/TMP> cat input.txt
abcdefghij
D$mhtt
$ sed '${s/$/ \\/;a\
> -S "J"
> ;}' input.txt
abcdefghij
D$mhtt \
-S "J"
$

On my PC with Cygwin bash, the result is the same.

Are you sure that D$mht is on the last line ?
An empty line at the end of the input file will give the result you got.

Yes, I think its not the last line of the page. An enter character is present in the last

 -s \"J\"/g
 }'  FILENAME
