Cron not working


Hello All,
I have been trying to schedule a task using cron only to realise that it is not working.
Code:
$ ps -ef | grep cron
root      2964     1  0 Nov12 ?        00:00:00 crond
root      2178  2964  0 14:20 ?        00:00:00 crond
seyiisq   2228 20774  0 14:20 pts/0    00:00:00 grep cron
$ crontab -l
* * * * * /usr/bin/date >> /xyz/cron_work.log
$
I have checked the file cron_work.log but it was empty.

Please any advise

However, when i queried the log in /var/log i got

Code:
# tail -10 /var/log/cron
Dec 29 14:29:01 computername crond[3215]: (seyiisq) CMD (/usr/bin/date >> /xyz/cron_work.log)
Dec 29 14:30:01 computername crond[3258]: (root) CMD (/usr/lib/sa/sa1 1 1)

Check the permissions on directory "/xyz" and on the file /xyz/cron_work.log.

As per Pingu; generally non-root users cannot write to '/' level dirs.

-rw-r--r-- 1 seyiisq dba 0 Dec 29 13:10 cron_work.log

Please, can anyone advise

I did the cron in seyiisq directory and still had the same result

seyiisq:compoutername:/xyz/seyiisq>crontab -l
* * * * * /usr/bin/date >> /xyz/seyiisq/cron_work.log

seyiisq:computername:/xyz/seyiisq>ls -lrt cron_work.log
-rw-rw-rw- 1 seyiisq dba 0 Dec 29 13:10 cron_work.log

After few minutes of monitoring the file cron_work.log remains empty.

I realise that there is no such as /usr/bin/date but /bin/date.

It was a silly mistake on my part
