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
Erik
