W|tee|F? DataPump doesn't work with Unix tee function?

I am trying to mechanize a datapump process and send an email if it fails. Problem is that  

expdp username/incrediblysecretpassword parfile=x.par|tee -a somefile  

does not, in fact, tee -a anything! I can do  

expdp username/incrediblysecretpassword parfile=x.par >somefile 2>somefile  

but that disables output to the screen, which the user running the job certainly wouldn't like. So... three questions...  

1. How do you get output onto the screen and into a file without using tee?
2. How in the world did Oracle manage to disable tee in the first place?
3. Why would they want to?

Other than that, best wishes to all my good friends for a lovely holiday and/or quiet list day!  

Thanks!

Bambi.
