This demonstrates the new lossy text compression tool, ltzip.

Here we demonstrate compressing a copy of the /etc/release file,

   $ ltzip -v release
   Read   : release                                       236 bytes
   Created: release.ltz                                   122 bytes
   Reduced: 48.31%

Great, the file was reduced in size by 48%! 
Lets compare the input and output files,

   $ cat release
                              Solaris 9 s9_58shwpl3 SPARC
              Copyright 2002 Sun Microsystems, Inc.  All Rights Reserved.

The compression algorithm is quite clever: it drops whitespace, the case 
of characters and zeros to save space.


The ltunzip command currently cannot uncompress the ltz files, but it 
can certainly try,

   $ ltunzip -v release.ltz
   Read    : release.ltz                                   122 bytes
   Created : release.ltz.un                                174 bytes
   Expanded: 29.89%

   $ cat release.ltz.un

Not all files compress well with ltzip, here we demonstrate ltzip on the
/etc/passwd file,

   $ ltzip -v passwd
   Read   : passwd                                       1742 bytes
   Created: passwd.ltz                                   1649 bytes
   Reduced: 5.34%
   $
   $ cat passwd

While the byte count has not been reduced by much, the characters themselves
have been reduced - and weigh less when stored on disk.


ltunzip on the compressed file looks like this,

   $ ltunzip -v passwd.ltz
   Read    : passwd.ltz                                    442 bytes
   Created : passwd.ltz.un                                 613 bytes
   Expanded: 27.90%
   $
   $ cat passwd.ltz.un
