I'm using Cron to run a script every minute.
My cron.php is located in
/var/www/test.com/public_html/cryptointerface/cron.php.
Using Crontab (crontab -e) I defined the setup as:
* * * * * /usr/bin/php /var/www/test.com/public_html/cryptointerface/cron.php
I let the cursor in an empty line right after this one.
After saving I got the message: installing new crontab.
The problem is that although syslog suggests that Cron is executing, it does not have the supposed effect. cron.php contains very basic code for writing something to file.
There is something that I'm missing, however I don't know what. All this is in a Ubuntu server.

My cron job keeps failing in cPanel:
/bin/sh: /opt/cpanel/ea-php73/root/etc: is a directory
I have changed the code, previously it was /usr/local/bin/php
This is the full code:
0 0,12 * * * /opt/cpanel/ea-php73/root/etc /home4/***/****.org/api/fetch.php
Does anyone know the reason? The file fetch.php works fine otherwise. How do I know where the PHP command is?
If you want to run a PHP file in a cron job, you should run with the PHP interpreter. But your error shows that the cron job is running by the Bash interpreter.
This means you have issue with this part /opt/cpanel/ea-php73
You should either revert your interpreter back to /usr/local/bin/php
Or you can use the curl command to run the webpage from an external source.
Eg: 0 0,12 * * * curl ****.org/api/fetch.php
In the PHP script, you're directly executing an incorrect shell command. Probably a missing / prefix in a path.
As implied in the title, the Cron Job is supposed to execute a php file (update.php, to be specific). The php file then writes to a csv file stored in the same directory.
I have the time set to * * * * * so that it executes every minute. The command is written as follows:
php -q /home//public_html/wallboard/update.php
I don't believe this is causing any errors, though it also doesn't seem to write to the CSV file. When I visit update.php in a browser, however, it executes and writes to the CSV file immediately. I'm not experienced with Cron Jobs and I'm sure there's an issue, but I don't know what exactly that issue is. Let me know if you have suggestions/questions. Any help is appreciated!
Current Command:
* * * * * usr/bin/php -q /home/<user>/public_html/wallboard/update.php
update.php:
<?php
include('lib/HelpDeskView.php');
include('lib/WallboardDisplay.php');
include('helpdesk.csv');
$helpdesk = new HelpDeskView();
$text="\r\ntest,test,test";
file_put_contents( "helpdesk.csv" , $text, FILE_APPEND);
Since your script resides in your public_html directory you can use wget for your Cron Job
wget -O - -q https://yoursite.com/wallboard/update.php
-O - output is written to the standard output in this case it will go to the email address you specify in CPanel
-q quiet mode
IMHO the best way is to contact support and ask them about command line syntax.
This is how I'm doing it at my linux server using cPanel.
This runs script.php which is stored in public root. Course, replace <username> in command line with your username.
At another server I'm using same command line with /usr/bin/php instead of php at the beginning of line, but I'm aware that not all servers use same command line. Some require php-cli in command line instead of php, some don't "like" -f argument, etc. So try various combinations.
To find more suggestions check out this SO topic too: Run a PHP file in a cron job using CPanel
Important thing: When trying different commands wait at least a minute (this case) to see if it works because Cron doesn't fire your script immediately.
Try to execute the same command in PHP CLI and check if it gives you any error, you might be missing some libraries or references required for CLI execution.
/usr/bin/php -d register_argc_argv=On /home/USERNAME/public_html/DOMAIN/artisan AMIR:HOME
i want to set a cron job on a server but its not working. I know there are hundreds of links on web that shows how to setup a cron job but i cant seem to make it work. What im doing now is:
1) Running crontab -e.
Then it shows bunch of lines in the command line.
2) I go to the bottom and add */5 * * * * path/to/myfile.php
and then i exit the editor in command line. Please tell me whats wrong here. Do i need to put my file in a specific folder? or do i need to go to the desired folder and then use crontab -e, or something else. Please forgive me, this is my first cronjob, hoping to be better next time.
Here are the pictures of what im doing.
Did you restart the cron service after you updated the file?
Have you tried executing the php script from the command line first to verify that it's executing as expected? It might be that the cron task is executing but the script is failing. If the script is fine, you might want to try using php as a command followed by the path and filename of the php file and then quitting the execution after it's done with -q.
*/5 * * * * php path/to/myfile.php -q
The problem could well be that you are trying to execute a PHP file and your system is unaware of what to do with it.
Is your PHP file executable?
You can make it executable by running
$ chmod +x file.php
and if you add a shebang to it
#!/usr/bin/php
<?php
// ...
the PHP script can be executed by running
$ ./file.php
Alternatively, you need to run the PHP interpreter and pass it the path to the file as an argument.
$ php file.php
For reference, see:

I am trying to run in mac a php script using cron. I want this php script to run every one minute. I read several sources online and from my understanding is better if I use launchd. In any case, I try to make it work with cron and then if it works fine I might try to use launchd.
So here is what I do:
I wrote this command in a txt file:
* * * * * /usr/bin/php /Applications/MAMP/htdocs/php_test/main_script.php
There I have the path to php (I found it with the "which php" command) and the path to my php script.
I named the txt file: crontasks.txt and I run it through terminal with this command:
crontab /Users/dkar/Desktop/crontasks.txt
When I list the crons (crontab -l) I see that this job is listed. But nothing comes as output every one minute. The output is supposed to be an image stored in a specified folder. What am I missing here?
Thanks in advance

You might have a slight miscomprehension how crond processes the "crontab" files. It would suffice to run the command crontab -e, which would let you edit your personal crontab or you edit the system crontab.
If you use crontab -e it will open the default editor (vi/vim) and you can enter the line:
* * * * * /usr/bin/php /Applications/MAMP/htdocs/php_test/main_script.php
Then you simply save your file. If you want to use the system crontab you will have to edit it directly and enter the line. Additionally the system crontab has one more field for the username. Like this:
* * * * * /usr/bin/php root /Applications/MAMP/htdocs/php_test/main_script.php
On the next full minute your script will be executed by crond.
I am running Ubunutu Linux server, PHP5, Apache2 and am having trouble getting any sort of cronjob to run through the crontab.
I edit the crontab using
crontab -e
I save the file I want to run:
*/5 * * * * php /home/user/public_html/crx/cronx.php
it saves fine. I can run the file from the console and goes through fine. I can't even find any existing logs for the file. I checked cron was running, stopped and started... no change.
The current php file is just a simple test script that inserts a single line into a database.
I checked the permissions for the file and has read and write. Am absolutely stumped. I can't seem to get ANYTHING to run through cron. Is there something I can run to test permissions?
EDIT
I have also tried the following command
/usr/bin/php /home/user/public_html/crx/cronx.php
I used whereis php and which php to locate and confirm it is all running in the right area
You have too many * values for your times.
Also, cron may not have a PATH set up correctly to use PHP.
Instead try:
*/5 * * * * /usr/bin/php /home/user/public_html/crx/cronx.php
Where /usr/bin/php is the actual path to PHP. From the console you can run which php to see the path to the PHP binary you should use.
EDIT: Here are a couple of more things to try in order to troubleshoot:
# see if cron is running just by having it create a file
*/5 * * * * touch /tmp/crontab-$(date +%s)
Another option:
Set the permissions of your PHP script to 755, and change the beginning to:
#!/usr/bin/php -q
<?php
// rest of script
Then change your cron tab to:
*/5 * * * * /home/user/public_html/crx/cronx.php
I'm still not sure if cron is the issue or the running of the PHP script.
