RE: Unix tee command

Erik:

This is from the HP-UX man page for tee:

 DESCRIPTION

      The tee command transcribes the standard input to the standard output
      and makes copies in the files.

What this means in relative English is that the output is recorded to a file
(as in script_file > log_file) but you see it on the screen (as in
script_file, which normally comes to STDOUT). We use this for automated process run by BMC's Enterprise Control System, where I want a log file on my machine, and the ECS wants a copy for it's sysout log.

HTH,
Mike

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.
