The man page says:
"TEE(1)                           User Commands                          
TEE(1)
 
NAME
       tee - read from standard input and write to standard output and files
 
"
therefore, for example:
who | tee filename_1 filename_1
sends the results of 'who' to STDOUT, and to two files (filename_1 and 
filename_2).
I haven't tried this myself, but that's what the man page says, and 
"UNIX in a Nutshell" agrees.
Hope this helps.

Fred James
