--------------------------------------------------------------------------

Fix for bug #48734 was this:

-if udm settings/portal_entry list "$@" --filter cn=teacherconsole | egrep -q ^DN; then
+if udm settings/portal_entry list "$@" --filter cn=teacherconsole | egrep ^DN > /dev/null; then

--------------------------------------------------------------------------

"grep -q" terminates and closes its stdin when it has a first match.
UDM CLI should handle an IOError in its list/print function.
