This has worked for me before:

diff -Nau first second | grep '^+'

This assumes that first and second are sorted.

I used the sort command to make two lists.  One list has everything on the first list and more.  They are already alphabetically sorted.  I want to know what is on the second list that is not on the first list.  I am trying to use diff but perhaps there is a better way.   I tried awk and an ugly egrep and now I am giving up and asking for help.  Thanks for your time.

Sincerely,
