Since you mention /etc,  re you dealing with IBM's service convention:
?
... Because IBM products do not create files into /etc or /var, there is no
possibility that SMP/E installation of an IBM product or service will 
overlay
your own files within /etc or /var.
(more in a subtopic)

"diff", recommended by David C. Can  be useful.  After
diff -r dir1 dir2 > diff-results.txt

Inspect diff-results.txt and do one of the following:
o Copy selected members from the other directory
o Use edited diff-results.txt as input to /bin/patch.
o Manually edit selected members.

Does IBM recommend making changes to /etc as SMP/E USERMODs and
using established techniques for reconciling USERMODs?

ISRSUPC and IEBUPDTE appear to be irrelevant.

I nadn't known about that:
Guideline: The dircmp utility is fully supported for compatibility
with older UNIX systems. However, use diff -r instead because
it might provide greater functionality and is considered the
standard for portable UNIX applications as defined by
POSIX.2 IEEE standard 1003.2-1992.

Now that I do, I regret it.  I'll stay with David C's:
diff  
https://www.ibm.com/docs/en/zos/2.4.0?topic=descriptions-diff-compare-two-text-files-show-differences

(but dircmp does have a simpler parameter list.)

Do you want to compare the file names in the directory, or the names and 
content of the files?

Re: USS compare

[Charles Mills]

Does SUPER-C support UNIX files?

Also, /etc is a directory, not a file, right? Do you want to compare two files, 
or the contents of two directories?
