I don't believe there's a way to open a file by inode.  You need
the name and finding the new name won't be easy in general.  You
could check all the files in the directory.

In any case, the compression programs will create a brand new
file with a new inode.  I just tested it with gzip:

% ls -li group
  26585 -rw-r--r--    1 blair    arbz          820 Nov 23 17:22 group
% gzip group
% ls -li group.gz
  26586 -rw-r--r--    1 blair    arbz          439 Nov 23 17:22 group.gz

stat().
