2**** cd $PROD_RAILS_ROOT && ./rake --silent users:update RAILS_ENV=production
What does 2 mean here? Is it every 2 min.
each hour to the second minute your job is executed.
00:02
01:02
02:02
03:02
04:02
etc...
If you want each 2 minutes it's :
*/2 * * * *

I would like to run the cron job every 20 minutes between 9 AM and 11 PM and once an hour after 11 PM until 9 AM.
cron job settings
I created 2 cron jobs for the same script to achieve my goal. Did I do it correctly?
Thank you.
Not really. There are two issues:
you run the script also on 23:20 and 23:40
you run the script twice from 09:00 till 23:00 every hour.
The way to do it is:
*/20 9-22 * * * command
0 0-8,23 * * * command
You can validate this using crontab guru
I am running a cron job which will run at every 5 minutes.
Now Let's say i have started job on 04:02 so it will execute at every 5 minutes so will execute on 04:07, 04:12, 04:17 etc...
Let's say i have started job on 13:18 so it will executed at 13:23, 13:28, 13:33 etc...
But what i want is it should only execute in multiplication of 5 minutes means if i create job on 04:02, it should start executing from 04:05, 04:10 and so on.
And if start job on 13:18, it should start executing from 13:20, 13:25 and so on.
So how to achieve this?
Try this:
0,5,10,15,20,25,30,35,40,45,50,55 * * * * <Your command>
*/5 * * * *
this should be what you want .
i have two cronjobs, i want to run the two cronjobs at a small gap of ten minutes. once in two days, at 0100 hours and 0110 hours
this is what iam trying.
0 1 */2 * * job1.sh
10 1 */2 * * job2.sh
job1 is not working as expected. it runs twice everyday.
job2 runs as expected (once in two days).
what am i doing wrong?
You need to add the binary executing the script, as well as the complete route to your file:
0 1 */2 * * /bin/sh /route/to/your/file/job1.sh
10 1 */2 * * /bin/sh /route/to/your/file/job2.sh
/bin/sh can be another thing, just get it from which sh.
I have a php script which crontab executes every 30 minutes, during off-peak hours around 2-7am I don't get much traffic and so I wish to not run the script during these hours.
I'm not sure how to make a cronjob that will do this as I would find it hard to test.
The cronjob I have at the moment looks like this
*/30 * * * * /usr/bin/php /var/www/update/inv.php
*/30 0-1,8-23 * * * /usr/bin/php /var/www/update/inv.php
the range is inclusive, so 0-1 will do 00:30, 01:30, then 8-23 will do 0830 to 2330
ref: http://team.macnn.com/drafts/crontab_defs.html
You can restrict the hours you want the job to run.
*/30 0,1,7-23 * * * /usr/bin/php /var/www/update/inv.php
The times will be every 30 minutes until 0130. It won't run at 0200. The next run will be at 0700 and then every 30 minutes.
There's quite a good article here on how to set up the cron:
http://en.wikipedia.org/wiki/Cron
I am trying to setup a cron job on a Ubuntu server. We want the cron job to run the script at certain times of the day and on some specific days of the week. For example, we want to setup a cron job that runs the script with the following sequence:
Execute the script every 2 minutes from 9 am to 2 pm during the weekdays.
This is what I have been able to do so far:
*/2 09-14 * * * /path_to_script
What should I do for the weekdays?
Same as you did for hours:
*/2 09-18 * * 1-5 /path_to_script
0 and 7 stand for Sunday
6 stands for Saturday
so, 1-5 means from Monday to Friday
You state 2pm in your requirement, hour range should end at 14 instead of 18 (which is 6pm).
*/2 9-14 * * 1-5 /path_to_script
man crontab
http://unixhelp.ed.ac.uk/CGI/man-cgi?crontab+5
In fact the last hour you want the script to run is 13:00 to 13:59, so you want:
*/2 9-13 * * 1-5 /path_to_script
meaning the first runtime will be 9:00, then 9:02, and so on until 13:58 which will be the last run as 14:00 is not included.
