This isn't simple, and can change the order of your output, because it means making one stream print into two separate places. To do that, you need to use tee or something like tee and connect to them with fifos.
This can change the order of your output because the path is no longer direct. stderr was guaranteed to be unbuffered, before, but now must pass through several buffers on its way to the terminal.

Reason: -a for append
How can I redirect and append stdout and stderr to a file when using cron? Here is my crontab file:
*/5 * * * * /dir/php /dir/process_fns.php >>& /dir/dump.txt
Cron gives me an 'unexpected character found in line' when trying to add my crontab file.

But during script execution I would like the output come back again to screen, how to do that?
Thanks
