Ofcourse , CarloM is right. diff command tells us the differences between two files.So if we remove 6,7d5 or any such information from output the remaining information will be useless.Although the above code completes the asked requirement.
sorry friends...I made a mistake...I didnot paid attention on the line "can you please tell me why I'm getting them" of post #3.That is why I have written above not required code.
Now
Here is an explanation of output of diff command:
means append line1 and line2 after line 0 of first file
means change line 2 of first file with line 4 of 2nd file
and
means delete line 4 of first file
so, here a means append, c means change and d means delete
number before a or d or c refers to line number in file1
number before a or d or c refers to line number in file2
Finally, if you follow the modifications suggested by diff, then you are going to make both queried files identical.

bdiff
bdiff(1) General Commands Manual bdiff(1)NAME
bdiff - Finds differences in large files
SYNOPSIS
bdiff file1 file2 [number] [-s]
bdiff - file2 [number] [-s]
bdiff file1 - [number] [-s]
The bdiff command compares file1 and file2 and writes information about their differing lines to standard output. If either filename is -
(dash), bdiff reads standard input.
OPTIONS
Suppresses error messages. (May either precede or follow the number argument if it is specified.)
DESCRIPTION
The bdiff command uses diff to find lines that must be changed in two files to make them identical (see the diff command). Its primary
purpose is to permit processing of files that are too large for diff.
The bdiff command ignores lines common to the beginning of both files, splits the remainders into sections of number lines, and runs diff
on the sections. The output is then processed to make it look as if diff had processed the files whole.
If you do not specify number, a system default is used. In some cases, the number you specify or the default number may be too large for
diff. If bdiff fails, specify a smaller value for number and try again.
Note that because of file segmenting, bdiff does not necessarily find the smallest possible set of file differences. In general, although
the output is similar, using bdiff is not the equivalent of using diff.
NOTES
The diff command is executed by a child process, generated by forking, and communicates with bdiff through pipes.
It should not normally be necessary to use this command, since diff can handle most large files.
EXIT STATUS
No differences. Differences found. An error occurred.
