You bet Richard,

try diff httpd.conf httpd.conf.bk > /tmp/diffs

This will output the differences to the tmp file. There are several variants of the diff command - man diff for the details.

Use bdiff (diff for largefiles)

Just run,

diff httpd.conf httpd.conf.bk >httpd_diff.txt

All the differences will be stored into the output file. Do "man diff" for detail description with "diff".

sdiff httpd.conf httpd.conf.bk >httpd_diff.txt, see man sdiff

You may use diff:

Ex.
$ diff file file.bk > dif.txt
