actually a new start title for each diff entry (sorrie not keeping it in separate files)
so what I tried to do was
x=1
while ((x<$num_lines)) ; do
sed "${x}q;d" file1 > final_file1
sed "${x}q;d" file2 > final_file2
read final1 < final_file1
read final2 < final_file2
echo "Differences between " $final1 " and " $final2 >>final_difference
diff $final1 $final2 >> final_difference
((x=x+1))
done
exit 0
and it does add a title on the top of each difference but then gives gibberish at the end for files that did not have a diff..

Hi,
When I run the diff command using diff -yt file1 file2, I get the output in which original lines are truncated.
I tried using -W switch with diff. However, that does not produce exact output as I want. Is it possible to show entire line of file1 and file2 in diff command's output?

BZDIFF(1) General Commands Manual BZDIFF(1)
NAME
bzcmp, bzdiff - compare bzip2 compressed files
SYNOPSIS
bzcmp [ cmp_options ] file1 [ file2 ]
bzdiff [ diff_options ] file1 [ file2 ]
DESCRIPTION
Bzcmp and bzdiff are used to invoke the cmp or the diff program on bzip2 compressed files. All options specified are passed directly to
cmp or diff. If only 1 file is specified, then the files compared are file1 and an uncompressed file1.bz2. If two files are specified,
then they are uncompressed if necessary and fed to cmp or diff. The exit status from cmp or diff is preserved.
