Thread: crontab repeats several times per minute


hi
i'm using ubunut 12.04 , running cron job.

here coll1.sh file:

cd /home/erin/stuff/img

a=`date +%s`
b=${a}_4.jpg
wget -o $b -q "http://www.houstontranstar.org/snapshots/cctv/4017.jpg"

, here crontab file:

*/2 18-19 3 8 6 /home/erin/stuff/coll1.sh

runs 4 times per minutes , skips 9 minutes.

suggestions doing wrong, please?

thanks,
erin

which crontab file, /etc/crontab or user-defined crontab in /var/spool/cron? if entry in /etc/crontab, needs username between time entries , command run.

these times:
code:
*/2 18-19 3 8 6
the script should run every other minute between 6 , 8 pm on 8/3. don't know why final 6 there; means saturdays.

schedule trying set here?

it's not possible cron job run several times minute since cron daemon wakes once each minute. else going on.

see in log files job?

hello! i'm trying setup software raid on server, fail @ first step: code: root@sandnabba:/root# mdadm -c /dev/md0 -c512 -l5 /dev/sdc1 /dev/sdd1 /dev/sde1 mdadm: no raid-devices specified. what doing wrong!? are sure -c equivalent --create? also, think need space after -c , -l options, value shouldn't command, or should have = between. @ man pages mdadm , double check spelling.
