If all the users' home directories are in /home, then you probably
just want something like:

  find /home -name .rhosts -print

If you really *must* parse /etc/passwd, because your system is set up
in a strange way, you could use a shell script which does something


cat /etc/passwd |
while read pwline
  user=`split -d: -f1 $pwline`
  home=`split -d: -f6 $pwline`
  found=`find $home -name .rhosts -print`
  if [ ! -z "$found" ]; then echo "Found for $user: $found"; fi

You could also write a Perl script to do the same.
