Script to compare binaries
Hi All,

I am very new to scripting and wanted to write a script for comparison of folder including binary files like ear's and jars. Following is the job for which I need it:

1. Compare two folders recursively
2. Compare the binaries like ear's but exclude files like MANIFEST files
3. Display the result of the comparison flagging only the changed files.

I did try cmp but it only flags if there is a difference or now.

The ear's that I am comparing always have a new Manifest file in them when I compile but the classes remain the same. Hence I want to ignore the manifest files and just compare the classes.

Any help with this is much appreciated.

zdiff

ZDIFF(1)						      General Commands Manual							  ZDIFF(1)

NAME

       zcmp, zdiff - compare compressed files

SYNOPSIS

       zcmp [ cmp_options ] file1 [ file2 ]
       zdiff [ diff_options ] file1 [ file2 ]

DESCRIPTION

       Zcmp  and  zdiff are used to invoke the cmp or the diff program on files compressed via gzip.  All options specified are passed directly to
       cmp or diff.  If only one file is specified, then it is compared to a file with the same name without the .gz extension. 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.

       When  both files must be uncompressed before comparison, the second is uncompressed to /tmp.  In all other cases, zdiff and zcmp use only a
       pipe.

SEE ALSO

       cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1)

BUGS

       Messages from the cmp or diff programs refer to temporary filenames instead of those specified.
