The literal string aaa-bbb-ccc-a file that is in file2 does not appear anywhere in file1. Why do you think there should be any output???

If file2 contained:
Code:
aaa-bbb-ccc-a

instead of:
Code:
aaa-bbb-ccc-a file

then the command:
Code:
fgrep -x -f file2 file1

or:
Code:
grep -Fx -f file2 file1

should do what you want.
