sed append text - not working

Hi,
I have the folowing entry at the end of a file ( called goods):
logger

I need to change this to :
logger WAC



I have tried:
$ sed -s '/logger/a\WAC' goods

But that does not work

Any help please appreciated

thanks
Pete.

If you want to ensure the substitution only
takes place at the end of the file, and not
for any else occurrence of "logger":

sed '$s/logger/& WAC/'


The a operator works as advertised:

sed -s '/logger/a\
WAC' goods

(on two lines)
But it will append a line with "WAC".
