Run cron job every 2 minutes except the first minute "0" of the first hour "0"

Closed 3 months ago.
I need to run a python script that starts at 11:30am and then runs every 30 mins till 7PM every day.
The expected included intervals will be: 11:30, 12:00, 12:30, 1:00 ...... 7:00
I have currently defined the Cron Job as:
*/30 11-19 * * * /usr/bin/python3 /mnt/h/WorkSpace/Projects/Backlog_Buddy_Bot/CTest.py
Current Output Intervals: 11:00, 11:30, 12:30, 1:00 ...... 7:00
The problem that I am facing here is this expression includes 11:00 which I dont want. Is there a way I can fix this or is there any alternate scheduler which lets me achieve this?
Disclaimer: I have never run the script till 7:00PM since the starting time has been an issue, so I am not sure if this includes 7:30 as well.
you can use 3 cron job for it.
1-
00,30 12-18 * * * /usr/bin/python3 /mnt/h/WorkSpace/Projects/Backlog_Buddy_Bot/CTest.py
2-
30 11 * * * /usr/bin/python3 /mnt/h/WorkSpace/Projects/Backlog_Buddy_Bot/CTest.py
3-
00 19 * * * /usr/bin/python3 /mnt/h/WorkSpace/Projects/Backlog_Buddy_Bot/CTest.py
I have a cron job that I want to run at 8 minutes past the hour, at 18 minutes past the hour, at 28 minutes past the hour, and so on. I tried this but got an "invalid minute" error.
8/10 * * * * /home/snrub/file.php
Can this be done?
It sure can!
08,18,28,38,48,58 * * * * /home/snrub/file.php
I am trying to run nodejs script in Linux using nodejs cron module with cron pattern = 0 00 05 * * * but instead of running once at 5 AM it is running twice once at 1 AM and again at 5 AM
What cron pattern should I use to run once at 5 AM every day
Checkout https://crontab.guru/ - I use this resource all the time.
From that site, and in general from my experience with Cron expressions, what you want is:
0 5 * * * /path/to/your/script
The pattern works out to:
0 - at 00 minutes
5 - at hour 05
* - every day of the month
* - every month of the year
* - every day of the week
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:

I want to run a php script every 10 minutes, between the hours of 9:30AM - 4:00PM
I googled before asking, and didn't have any success.
Anyone know how to do this? Or point me in the right direction?
Thank you
Try the following three lines in crontab
0,10,20,30,40,50 10-15 * * * # Every 10 minutes for the hours 10am - 3pm
0 16 * * * # 4pm
30,40,50 9 * * * # and 9:30, 9:40, 9:50
Run it from cron in every 10 minutes, check th date in PHP do nothing if it's outside the range.
*/10 * * * * /usr/bin/php /path/to/your/script.php
