thanks for quick responses!
people suggested CHGRP -R (I'm talking about MANY directories and the files in
those directories are may be members of several different groups) or swap the
definitions in the GROUP file (Sorry but we have to use the official ID NUMBER
as dictated by SAP/ORACLE)
Thanks to the following persons who gave scripts to accomplish the task, using
FIND and shell utilities plus one perl:

Well the first thing that comes to mind isn't exactly slick but it would get
the job done...
# find /directory -group 101 -print > dba.txt
# find /directory -group 102 -print > sapsys.txt
# for i in `cat dba.txt`; do chgrp dba $i; done
# for i in `cat sapsys.txt`; do chgrp sapsys $i; done
and your done. It will take a while but it should work. If you get any
better methods, more power to you. Please summarize and let us know.
Cheers,

Make Sun come and fix it. :)

find . -user 101 -print > /tmp/101.list
find . -user 102 -print > /tmp/102.list
(pick your favorite shell here, I use tcsh)
foreach z (`cat /tmp/101.list`)
chgrp 102 $z
end
foreach z (`cat /tmp/102.list`)
chgrp 101 $z
end

How about:
If you're using local /etc/group files, why not just make the switch 'official' and swap them in the group file?
or:
find / -group 101 -exec chgrp 103 {} \; # or some other unused group find / -group 102 -exec chgrp 101 {} \; find / -group 103 -exec chgrp 102 {} \;
you get the idea..
---------------------------------------------------------------------------------
I'd do a little smoke and mirrors action
Create a user named something other than sapsys and dba....such as tempuser
1) find / -user dba -exec chown tempuser {} \ 2) find / -user sapsys -exec chown dba {} \; 3) find / -user tempuser -exec chown sapsys {} \
.....or something like that

if you change the group file, the changes should occur on each file.
If you still need to change files after that, you can run find like this:
find <starting_dir> -group <group_name> -exec chgrp <new_group_name> {} \;
or find <starting_dir> -gid <group_number> -exec chgrp <new_group_name> {} \;
or if you want to change them all to one group then chgrp -R <new_group_name> <directory where you want to start>

Ed, It sounds like you need a way to break up the files into smaller groups.
One way is to pipe the output of ls to the split command, then use chgrp `cat xaa` chgrp `cat xab` etc.
Another way is to use find, which will walk the whole directory tree one record at a time.....
find . -exec chgrp 102 { } \;
the "\;" is the end-of-line for the exec parameter to find.....

You can find all files with group 101 by doing:
find /basedir -group 101 -print
Doing this twice gives you a list of files to change, and from there you can work it out yourself I guess.

One possiblity that comes to mind is find and xargs. You could create a temporary new group and use something like:
# change all the files with gid 101 to tmpgrp find / -group 101 | xargs chgrp tmpgrp
# change all files with gid 102 to 101 find / -group 102 | xargs chgrp 101
# change all the tmpgrp files to gid 102 find / -group tmpgrp | xargs chgrp 102
Just a thought...
