bash - How can I direct output from a program to the console and a log file at same time? -

-

How can I print output for the terminal and file at the same time? 

  $ Pearl Foo.PL> Foout.txt

does not allow me to see the live process.

Is there any way that I can see the output process in real time and finally output the screen on a file?

perl foo.pl | Foout.txt

Maintenance as TDI) = Maintenance. Where are kept. Road is empty This works very well. But what I want to do now will only remove those lines, if they have more than 2 duplicates. Thanks with in the form of CT (select row_member ( )) (Divol1 by split, dupol2 sequence by id) from table as rn) from cte where rn & gt; 2; - or & gt; 3 etc. The query is being classified by a 'line number' for each record, (Dupl 1, Dupl 2) and ordered by ID.
