Cron job minute to tomorrow

Question

I am going to invoke a PHP file call through a curl in a schedule. I think the script will run every 23:59:59 or just a minute before the day turns tomorrow. What is the best approach for this? Pretty embarrassed about cron settings.

I need to make sure that I run exactly one second before the next day.

Answer 1

To run the script every day at 23:59:00, use the following:

59 23 * * * root /path_to_file_from_root 

Seconds cannot be determined using Cron , but it should do it for you.

To execute the script at 23:59:59, use the PHP sleep() function to delay the execution of the script by 59 seconds. I would advise in 58 seconds, just to make sure the script doesn't linger until midnight.

It is very simple, you can make it a little more complicated and run tests to ensure that the script always starts at 23:59:59, getting the time and lingering accordingly. However, this is not necessary.

 <?php // Any work that the script can do without altering the database, do here // Delay the script by 58 seconds sleep(58); // Carry on with the rest of the script here, database updates etc ?> 

Answer 2

 Minutes [0-59] | Hours [0-23] | | Days [1-31] | | | Months [1-12] | | | | Days of the Week [Numeric, 0-6] | | | | | * * * * * home/path/to/command/the_command.sh 59 23 * * * home/path/to/command/the_command.sh 

Answer 3

Start editing crontab with

 crontab -e 

or

 vi /etc/cronatb 

It depends on the distribution.

 59 23 * * * root /path/to/your/php/file.php 

Note that the “root” column means the name of the user under which the task is run, it may not be available on your system.

Try to run

 man crontab

You can configure it to run exactly 23:59:00 every day, take a look at the examples by setting it here . In particular, see Example No. 1, which explains how to install the crown within a certain time.
