I am writing this to use as a shell script, that I can run on multiple files by typing just: mydiff firstfile secondfile

I have been working and have this code:

diff $1 $2 | sed -e 's/^<*/file1:/g' -e 's/^>*/file2:/g'


I type: mydiff firstfile secondfile
It is running the diff but output comes out like this:

file2:file1:>
file2:file1:>
file2:file1:>
file2:file1:>

Thanks for the reply

bzcmp

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 |
       +--------------------+-----------------+

       +--------------------+-----------------+
       |Interface Stability | Committed       |
