ha ha thanks agama, I guess i'll keep my temporary files then , they're not so bad after all!!
It's a pity though, i was hoping some kind of easy redirection like
Code:
ls not_a_file a_file >$OUT 2>$ERR # obviously does not actually work!
It wouldn't seem so hard to provide in shells nowadays, since the same can be achieved with a few commands using files. Anyway, I guess the question of whether it is actually useful or not is worth asking.
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.

Zach Curtis

How can I pipe both stderr and stdout into tee so both stderr and stdout are copied both to the display and to the log file?
Thanks,

working on a c sell script
I think I understand the concept of it, which is:
filename >> file.txt (to appaend)
or filename | tee -a file.txt (to append)
The problem is that my shell script is used with several parameters, and these commands don't seem to work with just filename. They... (2 Replies)
