#! /bin/bash

f1="tfile1"
f2="tfile2"
f1out=$f1".out"
f2out=$f2".out"

cat tfile1 | cut -c10- >$f1out
cat tfile2 | cut -c10- >$f2out

diff $f1out $f2out

results in:
Code:
> cfile
4c4
< good file
---
> bad file

Sorry, can't express enough of my thanks~~~~~~
I was stuck on it for so long.
THANK YOU

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.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +--------------------+-----------------+
       |  ATTRIBUTE TYPE    | ATTRIBUTE VALUE |
