That's a rather unusual way to arrange things, often you want to see if all lines in one file are present in another, or some such.
Anyway, uniq can tell you whether two adjacent lines are identical. To just extract the first two lines from a file, use head -n 2
If this prints a 2 and the line then the two lines are identical, otherwise it will print two lines with an occurrence count (of course, one each).
This is pretty bare-bones but perhaps you can add some details about what sort of application you have for this problem. Maybe you also want to look at diff and cmp

DIFFPDF(1) General Commands Manual DIFFPDF(1)NAME
diffpdf - compare two PDF files textually or visually
SYNOPSIS
diffpdf [file1] [file2]
DESCRIPTION
This manual page very briefly documents the diffpdf command. (Click the GUI's Help button or press F1 for more information.)
DiffPDF is a GUI application used to compare two PDF files.
By default the comparison is of the words on each pair of pages, but comparing character by character is also supported (e.g., for logo-
graphic languages). And there's also support for comparing the pages by appearance (for example, if a diagram is changed or if a paragraph
is reformatted, or a font changed). It is also possible to compare particular pages or page ranges. For example, if there are two versions
of a PDF file, one with pages 1-12 and the other with pages 1-13 because of an extra page having been added as page 4, they can be compared
by specifying two page ranges, 1-12 for the first and 1-3, 5-13 for the second. This will make DiffPDF compare pages in the pairs (1, 1),
(2, 2), (3, 3), (4, 5), (5, 6), and so on, to (12, 13).
If the program is passed two PDF filenames on the command line it will start up and compare those files in Text mode (or in Appearance mode
if the filenames are preceded by -a or --appearance).
