Issues with using sed with word delimiters \< and \>
sed is not applying /d "delete line" option when I also include match word options \< and \>

examples...
echo cat | sed '/\<cat\>/d'

will return cat for some reason

echo cat | sed "/\<cat\>/d"

will also still return cat.

Of course I can just run this... echo cat | sed '/cat/d' and it will apply delete option to line thus returning nothing.


But I need to match the word exactly.... so any advise of how to get around this?
I'm running on AIX. Same results with with ksh or bash shell.
