My current GID are all < 100, however I am having issues now with this. Does anyone know of a way to change all GID's to perhaps add 100, IE so GID now = 23 will = 123. I am running an NIS network so changing the table is easy , however finding all the files on all my filesystems and modifying them is what i need to find if there is an easy way to do this.....

Check the man page for the find command - there should be an option for finding files that belong to a certain group:

Example: find /some-starting-directory -group 23 -exec chgrp 123 {} \;

The best way to do this is with PERL. Perl can walk a file system faster than anything else. Do something like this.

#!/opt/perl/bin/perl

use File::Find;
find \&wanted, "/";
sub wanted {

my $dev; # the file system device number
my $ino; # inode number
my $mode; # mode of file
my $nlink; # counts number of links to file
my $uid; # the ID of the file's owner
my $gid; # the group ID of the file's owner
my $rdev; # the device identifier
my $size; # file size in bytes
my $atime; # last access time
my $mtime; # last modification time
my $ctime; # last change of the mode
my $blksize; # block size of file
my $blocks; # number of blocks in a file

#Right below here your telling lstat to retrieve all this info on each and every file/directory. Each and every file/directory is w
ritten to $_.

(($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,$atime,$mtime,$ctime,$blksize,$blocks) = lstat($_));

if ($gid <= "99" ) {
$NEWGID=$gid+99;
print "old $gid\n";
print "new $NEWGID\n";
system "chgrp $NEWGID $_;
}
}

I'm not sure if this is perfect but it should be pretty close.

I am assuming that this 'walks' the directory from that point forward or does something else have to be done.

P.S. Thanks very much BTW

Except for a missing " everything worked just fine. I am running the scripts (i modified the / to . so as to walk from the curent directory forward. But it works beautifully, thanks again.
