As its name suggests (it comes from plumbing), 'tee' sends its
standard input to two destinations, standard output and the named
file.  So, what 'tee' gives in this example is that not only does the
clamscan output go to /tmp/clamscan.log as it would with '>', but it
also goes to the screen as it is produced.  A frequent reason for
wanting to do this is if the process might take some time, and you
would like to monitor the progress (and maybe abort it if you don't
like it).  Even if it goes fast, though, you might use this just to
both put the information on the screen for immediate study and save it
in a file for more processing.
