I have a shell script that I'm looking to run daily, (to update CentOS and send out a confirmation email via SSMTP). The script is working ok, and sits in /etc/cron.daily, the problem is that it's running hourly, not daily at the time I specified.
My /etc/crontab file looks like this:
SHELL=/bin/bash PATH=/sbin:/bin:/usr/sbin:/usr/bin MAILTO=root # 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 # | | | | | # * * * * * user-name command to be executed 05 13 * * * root run-parts /etc/cron.daily 05 13 * * 6 root run-parts /etc/cron.weekly
Now, after editing this file manually, I read that I should have instead used the 'crontab -e' command, which I did, and the output looks like this:
05 13 * * * root run-parts /etc/cron.daily 05 13 * * 6 root run-parts /etc/cron.weekly
I also read that /etc/anacrontab has an effect on when jobs run, the output of this looks like this:
# /etc/anacrontab: configuration file for anacron # See anacron(8) and anacrontab(5) for details. SHELL=/bin/sh PATH=/sbin:/bin:/usr/sbin:/usr/bin MAILTO=root # the maximal random delay added to the base delay of the jobs RANDOM_DELAY=45 # the jobs will be started during the following hours only START_HOURS_RANGE=3-22 #period in days delay in minutes job-identifier command 1 5 cron.daily nice run-parts /etc/cron.daily 7 25 cron.weekly nice run-parts /etc/cron.weekly @monthly 45 cron.monthly nice run-parts /etc/cron.monthly
My intention was for the script to run at 13:05PM daily, however the script is actually running hourly at around 40 minutes past the hour, and I can't see anywhere in these 3 files where that's being triggered.
I happily schedule cron jobs with success in Ubuntu, but CentOS is proving to be a tad more complicated. Have I made a glaring mistake somewhere?
Any help greatly appreciated.
