  I guess this is of general interest... first you save the environment
via:
    set > my.env
on some really old copies of shell you must
    (set) 2>my.env

Then put the command(s) on the end of the environment and send to the
rsh:

    echo "pwd;ping pong;who" | cat my.env - | rsh elsewhere /bin/sh

Of course about the 2nd time you do it:
    ersh()
    {
      echo "$2" | cat my.env - | rsh $1 /bin/sh
    }

then you can say:
    ersh othermach.far.away "who;ping pong"
