Greetings! Does soemone have a clue, why cron would execute following line again and again? :roll: I added 3 */6 * * * root /var/bin/usage.sh > /dev/null 2>&1 with echo to /tmp/crontab. The script was started by cron at 6:02:04pm first and then over and over till 6:03:02. usage.sh contains: #!/bin/sh echo `uptime` - `date +'%Y%m%d%H%M'` - `cat /proc/net/dev | grep vlan1` > /var/www/usage The results are ok and then copied to another host, where they get parsed and logged. When one puts * * * * * to crontab, the followed command gets started always by cron and not only once a minute. Any hints? Regards, Judex Besides: Playing around with batbox is great!
