You can also use the -vf flags of grep something like this:-
This will display lines from file1 that are not in file2. No output infers that file1 lines are all found in file2, however there is no consideration on the order of the lines, if there are duplicate lines etc.
Would this do what you need?
I haven't got a SunOS server available to test on, so you might need to adjust your code to perhaps use fgrep and drop the -f flag.

diff3
DIFF3(1) General Commands Manual DIFF3(1)NAME
diff3 - 3-way differential file comparison
SYNOPSIS
diff3 [ -exEX3 ] file1 file2 file3
DESCRIPTION
Diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes:
==== all three files differ
====1 file1 is different
====2 file2 is different
====3 file3 is different
The type of change suffered in converting a given range of a given file to some other is indicated in one of these ways:
f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3.
f : n1 , n2 c Text is to be changed in the range line n1 to line n2. If n1 = n2, the range may be abbreviated to n1.
The original contents of the range follows immediately after a c indication. When the contents of two files are identical, the contents of
the lower-numbered file is suppressed.
Under the -e option, diff3 publishes a script for the editor ed that will incorporate into file1 all changes between file2 and file3, i.e.
the changes that normally would be flagged ==== and ====3. Option -x (-3) produces a script to incorporate only changes flagged ====
(====3). The following command will apply the resulting script to `file1'.
(cat script; echo '1,$p') | ed - file1
The -E and -X are similar to -e and -x, respectively, but treat overlapping changes (i.e., changes that would be flagged with ==== in the
normal listing) differently. The overlapping lines from both files will be inserted by the edit script, bracketed by "<<<<<<" and ">>>>>>"
lines.
For example, suppose lines 7-8 are changed in both file1 and file2. Applying the edit script generated by the command
"diff3 -E file1 file2 file3"
to file1 results in the file:
lines 1-6
of file1
<<<<<<< file1
lines 7-8
of file1
=======
lines 7-8
of file3
>>>>>>> file3
rest of file1
The -E option is used by RCS merge(1) to insure that overlapping changes in the merged files are preserved and brought to someone's atten-
tion.

Text lines that consist of a single `.' will defeat -e.
