Nothing happening in CRON

  • 772

I put in a command for crontab but nothing seems to be happening.

#vi /etc/crontab

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/
# For details see man 4 crontabs
# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  *  command to be executed
10 * * * * cd /var/www/html/mt; ./tools/run-periodic-tasks ~

And crond is running..

# service crond status

# crond (pid 7070) is running...

It suppose to rebuild a html from Movable Type every 10min. I am on Amazon EC2 Linux 64bit.

cron amazon-ec2 fedora

    For the system wide /etc/crontab you must also specificy which user to run as. That would be a column in itself, going after dow, but before the command being run.

    Also, as Ignacio just mentioned, for it to be run every 10 minutes, you want to use */10.

    Hence

    */10  *  *  *  *   USER   cd /var/www/html/mt; ./tools/run-periodic-tasks ~

  2. Your specification says "10 minutes after the hour". Try */10 instead.
