Talking simple "echo > qbc" cron jobs doesn't run


Hello

I need to update my DB twice a day.
So I started to do some experimenting on cron but it just doesn't work for me.

I tried it on my PC (FC3) and server (CentOS 3) but the results are the same.

My script looks like this
Quote:
#!/bin/sh
date > output
echo testing testeeing testening >> output
date >> output
By right it should output the results into a txt file (output) right.
But it doesn't.

I have run it on a terminal and the script woks fine.

I even tried it in an at job, it also works.

But for cron no results were found.
My "crontab -l" returns
Quote:
01 01 * * * /home/intuition/insert.sh
It should be running everyday at 0101 right. But it didn't

My /var/log/cron looks like this
Quote:
Jul 27 00:59:16 anima crontab[2925]: (root) LIST (root)
Jul 27 00:59:54 anima crontab[2929]: (root) REPLACE (root)
Jul 27 00:59:58 anima crontab[2930]: (root) LIST (root)
Jul 27 01:00:01 anima crond[1988]: (root) RELOAD (cron/root)
Jul 27 01:01:01 anima crond[2941]: (root) CMD (/home/intuition/insert.sh)
This is what I did
1. I type "crontab -e" and entered
01 01 * * * /home/intuition/insert.sh

2. I then entered ":wq" to write and quit the editor

Did I do something wrong?

I have even tried
crontab -l > mycron

then
vi mycron and entered 10 01 * * * /home/intuition/insert.sh

finally
crontab mycron

when 0110 come still no results

Please give some insights, please ...

I ran the exact same entries (except the time ofcourse) and got the outputfile correctly in my home folder.

A few things to try out:
- Give 'output' an absolute path, tho it did work with just output for me
- activate / install sendmail. Youll get any errors in a mail, sent to your user.

Now, im running dcron (Dillon's Cron daemon) that came with slackware, so the difference could be actually another crond, but the syntax should be the same.
