Redirect output to file from remote session

how can redirect output remote session local file? if add pipe tee or output-file at end of  an invoke-command cmdlet empty file created. file console output created ok local sessions.

i created remote session with

new-pssession -computername sharepointtest2 -credential fal\kraviss -name "newsession" -sessionoption (new-pssessionoption -nomachineprofile)

and ran with

invoke-command -session (get-pssession) -filepath "c:\documents , settings\kraviss\my documents\powershell\updatespperms.ps1"

is script using write-output, or write-host send results console?  write-host go straight console, , can't redirected.  should using write-output.
