Wow! I guess the question was too easy. I should have 
known this ... but had forgotten that time was going to stderr ...
Lots of responses! Thanks to everyone for the excellent
assistance!

Here's the original question:

> The script, in general, has something like this:
>
>   date
>   time mv /ip4700/A0/scratch/testfile-eds4 /testfile-eds4
>   date
>   time mv /testfile-eds4 /ip4700/A0/scratch/testfile-eds4
>   date  

And here are a couple of the typical responses.

--------------------------------

I think you probably need to redirect the output from stderr also.  When you
redirect using > only stdout is redirected.  To redirect stderr you need
something like this:

  script > log 2>&1

Where 'script' is the script you are running, 'log' is the log file.  '2' is
the handle for stderr and '1' is the handle for stdout so what '2>&1' does
is redirect stderr to stdout. 

---------------------------------


Time sends its output to stderr; you need to redirect stderr.

In csh:    <script>  >&  <file>
In sh:     <script>  > <file> 2>&1    

--------------------------------

I received responses from all these people! Thank you!
Hope I didn't miss anyone!
