Find two files containing strings or strings that are not included in shell scripts

First, the demand

Here, I simplify, because this afternoon operation both texts are 10 tens of thousands of lines, but only filter out these two files contain the same or different string ppid.

Two, step together

1. Document HA1

Abc

2. Document HA2

Acd

3. Find out that two files contain a string ppid

4.1 Modify $? Not equal to 0.
