Hello,
I want to compare two files. All records in file 2 that are not in file 1 should be output to file 3.
For example:
file 1
123
1234
123456
file 2
123
2345
23456
file 3 should have
2345
23456

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.
