crontab in Linux

I want to copy file from website and save in my server, when I run this command in shell prompt, it work correctly

root@web:~# wget -bO /web/web_ps/thex-new/crontab/DATA.HTM http://www.bankasia4u.com/Main/Bank..._Rates/DATA.HTM
2>&1 > /dev/nul

but when I run in crontab ( add 0 12 * * * ) it don't copy file. and I don't know where to see log file.


1. Why it doesn't work when I put in crontab. Is something wrong?
2. I test crontab in my computer. When it already run. It send email to me. I can check by use Pine. but this command don't send any email to me. Why it doesn't send?
3. When I run wget in shell. It also save log file (wget-log wget-log.1 wget-log.2 wget-log.3). If I run in crontab. Where it save logfile?
4. I don't know what " 2>&1 > /dev/nul" in command mean?

You may need to add the full path to wget in the crontab setup.

0 12 * * * /bin/wget ...

Yes, I add /usr/local/bin/wget

but it still don't work.

I'd do it another way...

write a little perl script with a LWP UserAgent to fetch the data for you - and hey, you could even parse it on the way in too.

Anyway, &1 > /dev/null and &2 > /dev/null cause any output to stdout and stderr to be redirected to /dev/null

Are you sure that you are running crontab after you have editedt the file.. eg

# vi /var/spool/cron/crontabs/root

[make changes and save]

# crontab /var/spool/cron/crontabs/root
