As said above I need the process to be hidden/name-changed for all users. Embedding it into another process like sshd is also acceptable.

Why would you want to do that?

Anyway, I think it's not possible using high level languages like bash or ksh.

Maybe Perl's "File::Tail" module could be useful.

Here is the very basic example from CPAN, slightly adjusted:

  use File::Tail;
  $file=File::Tail->new("/var/log/log.txt");
  while (defined($line=$file->read)) {
      print "$line";
  }

and here is the link, containing a more sophisticated example:
http://search.cpan.org/~mgrabnar/File-Tail-0.99.3/Tail.pm

You could of course go the very easy way by creating softlinks to "tail" as well as to "/var/log/log.txt":

cd /some/dir
ln -s /usr/bin/tail foo
ln -s /var/log/log.txt bar

Now you can run:

cd /some/dir
./foo -f bar
