With that syntax the output from "run" (which is almost nothing) is piped
to search.  Then you get the output from "dir files size all".  (To see
this enter    run dir files size all * | search STDIN shell    .)

You'll want to use "\|" above instead of "|" so that the piping
will be done in the background shell.

The first line of output will be unpleasantly indented.  That can be fixed
with

     run dir files size all * \| search STDIN .zoo | tee | echo ""

Here the (small) stdout stream from tee goes to "echo", which swallows it,
while the stderr stream goes to the console before the console output from
the background process.
