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
Erik
