This code is working fine, just want to ignore whitespace also as am doing for ignoring comments.
Below command will store the content of hostfile in array and print those lines of input file which is not there in hostfile.
Code:
 
awk 'NR==FNR{A[$1$2$3]=$0;next}
/^[0-9]/{if(!A[$1$2$3]){print $0}}' hostfile inputfile

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).
