The TEE command basically duplicates the output. It sends a copy to the
file specified and a copy to the standard output. This is the difference in
just redirecting it. When you redirect it, none goes to standard out, just
to the file specified.

I do not understand the difference between these two commands:
script_file > log_file
script_file | tee log_file
As I understand, the first runs and redirects its standard output to a log
file. The second runs and pipes its standard output to the tee command,
which copies its standard input into its standard output. I have been
instructed to use the latter, but dont want to do it blindly without
understanding why.
Thanks
