Trying to set up a couple of cron jobs in cPanel but since the system uses commandline for crons I can´t use parameters - this is a wordpress cron and relies on parameters in url.
How can i get this to work through commandline?
php -q /home/facebnzc/public_html/folkeuniversitetet/wp-cron.php?import_key=NAbeK7X&import_id=1&action=processing
This constant just enables or disables the check for events that are ready to fire. You still
add and manage events as we did up above. We just need to manually hit the wp-cron.php file in our WordPress install often enough to fire our scripts when needed.
If all you have are daily scripts, you can add a cron job like this via the crontab -e
command:
0 0 * * * wget -O - -q -t 1
http://yoursite.com/wp-cron.php?doing_wp_cron=1
Information on how to use cron can be found at its Wikipedia entry. Information on
how to use wget can be found at the wget manual.
The 0 0 * * * part of the preceding entry tells cron to execute this script at 0 minutes
on the 0th hour (midnight) every day of the week.
The wget -O - -q -t 1 http://yoursite.com/wp-cron.php?doing_wp_cron=1 part
uses the wget command to load up the wp-cron.php page in your WordPress install. The
-O - tells wget to send output to devnull, and the -q enables quiet mode. This will keep
cron from adding files to your server or emailing you the outputs of each cron run. The
-t 1 tells cron to try once. This will keep wget from hitting your server multiple times
if the first try fails. If the call to wp-cron.php is failing, the rest of your website is probably failing too; hopefully you’ve already been notified.
Be sure to change yoursite.com to your actual site URL. And finally, the ?doing_wp_cron=1 on the end of the URL is needed since wp-cron.php will check for that
$_GET parameter before running.

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've been having some issues with crontab recently. After switching servers, I realized none of my cronjobs are being run. After looking at PHP info, I realized php was run with CGI, so I realized I had to switch lynx -dump URL_HERE to php -q PATH_HERE.
In the actual PHP file, I stared it out like #!/usr/bin/php -q to define where php is located on my server. However, it's not getting run. I've even set up crontab to send me an email once anything runs. No email. I've checked my junk, trash, spam, and I've even tried switching emails. Nothing.
Here's what I have now: * * * * * php -q /home/USER/public_html/file.php.
If I copy & paste it into the command line, it works wonderfully. If I run it through crontab, it doesn't get run.
You are missing envrionment variables. Try a simple test like this
add this to your crontab
* * * * * set > /tmp/vars
wait 2 -3 minutes, go back and remove the crontab entry you just created.
Next,
From the shell command line you normally use
set > myvars
diff myvars /tmp/vars
This will show you the differEnce in envIrionment. Modify your cron job environment. Just add what is needed.
You can do a couple things in order to debug this.
1) In your crontab change your entry to:
* * * * * php -q /home/USER/public_html/file.php > /tmp/filecron 2>&1
Make sure you edit the entry by typing:
crontab -e
Then run:
tail -f /tmp/filecron
To debug the output as it runs.
2) As sudo user or root, tail the cron log to make sure your cron is executing properly:
sudo tail -f /var/log/cron
The first step will give you information related to the php file itself (syntax errors etc) if that is what is failing. The second step will help you out if the crontab itself is not configured properly.
You are intending this job to run every 5 minutes right ? This is what it will do with your stated line.
This is my first contact with cron jobs, so I'm sorry if my question sounds dumb.
BackWPup is for making a back up automatically after some period of time, but its own cron job does not work correctly. It starts only when I sign into wp-admin. So I decided to use the server's cron jobs, but I don't know how to. It says:
If you would use the cron job of your hoster you must point it to the
url: http://example.com/wp-cron.php
Also, I want to know how to remove a job.
Note: I have only ssh access, there is no hosting control panel. OS: CentOS.
I guess you should add the command
wget http://example.com/wp-cron.php >> /path/to/my/wp-cron.log 2>&1
to the crontab. Of course you can use any other CLI http-tool instead of wget, but it's the most simple I know and I think is sufficient here.
Call
crontab -e
then add a line like
0 * * * * wget http://example.com/wp-cron.php >> /path/to/my/wp-cron.log 2>&1
This will call this command every hour. For further information see man crontab.
I have several PHP files to be run by cron. I set up the crons using command-
crontab crontab.txt
Inside the crontab.txt file, I have written cron commands like this:-
#(Updating tutor activities) - every minute
* * * * * /usr/bin/wget -O - -q -t 1 http://project/cron/tutor_activities.php
But none of the functionalities are working (database queries, sending reminder mails etc.). Running the URLs manually works.
Then I put my mail address in MAILTO and received the mails. In the mail, I received entire HTML source of the page. What is expected in the mail? Why are my functionalities not working?
Updates
If I change my cron commands to
#(Updating tutor activities) - every minute
* * * * * /usr/bin/wget http://project/cron/tutor_activities.php
Still no success and this comes in my mail -
--15:03:01-- http://project/cron/tutor_activities.php
=> `tutor_activities.php'

index.html.1 has sprung into existence.
Retrying.
And lots of index.html.1 , index.html.2 files are accumulating in the root of my project. I do not want these files to be created. Just want the files to execute.
Same results if I use either of the two commands -
* * * * * /usr/bin/wget http://project/cron/tutor_activities.php
* * * * * wget http://project/cron/tutor_activities.php
running php command with MAILTO set sends me this error /bin/sh: php: command not found.
* * * * * php /path/to/test.php
So, I am not able to use php command.
I have written a simple mailto() inside my test.php. The mail does not come when run through cron (using both wget and php fails) but running the URL manually works.
My problem
To make it clear again, my main problem is that the functionality inside the cron files is not running. Creation of files is a secondary issue.
Any help would be appreciated
Thanks,

if you want to call an url as cronjob, you'll have to use somthing like wget. if it's a php-script on your server it would be easier to use php /...pathtomyscript.../cron/tutor_activities.php
try
which php
The path which is returned should be placed with the command which is passed to run the Cron file.If you are setting up the Cron through Shell,it won't give any problem,but to be assured,try giving absolute path when you are trying to run a php page.
/path/to/php /path/to/cron/script/
Try to give your comand like this,if the problem persists;feel free to discuss.
When you call wget with -O -, it will send the downloaded content to stdout, which cron is sending to you via the email message. In the first case, it's doing exactly what it should.
When you call wget witout the -O parameter, it will try to save the downloaded content as a file of the same name as the web page being downloaded. If it exists, it will add the incrementer to the name, as you saw. In this second case, it's doing exactly what it should.
It's not clear from your question where you want the output to go, but if you want to save the output to the same file each time, use -O myfilename.html.
If your running PHP from cron/command line make sure you put the full path to the php executable
It's entirely possible that PHP's not in the path within the cron environment - it's definitely not going to have the same setup as your regular shell. Try using the absolute path to BOTH the php interpreter AND the php script in the cron command:
* * * * * /path/to/php /path/to/test.php
As for the creation of files, you just have to add a redirect to your wget command:
wget -O - ... http://.... > /dev/null
-O - forces wget to write anything it downloads to standard output, which cron will then happily email to you. By adding the > /dev/null at the end of the command, this output will instead go the Great Bitbucket in the Sky. If you don't want wget's stderr output emailed either, you can also add a 2&>1 after the /dev/null, which further redirects stderr to stdout, which is now going to /dev/null.
I found the problem myself. I did not put the same URL in my crontab file which I was running manually and that was my mistake.
While running manually I was just typing test in the URL, my browsers's list of saved URLs was appearing and I was selecting the URL http://www.test.project.com/cron/tutor_activities.php, but in the crontab file I had put http://test.project.com/cron/tutor_activities.php. I was mistakenly assuming this would run http://www.test.project.com/cron/tutor_activities.php (because we have a rewrite rule present to add www)
But the rewrite rule was redirecting it to http://www.test.project.com/home. That's why the HTML content in the mails.
So, the most important thing to learn here is to make sure we don't miss the minute things and don't assume that we did everything correctly. In my case, better to copy-paste the working URL into the cron file.
An easy and secure (no tmp files) way to do this is to use bash's process substitution:
* * * * * bash -c "/path/to/php <(/usr/bin/wget -O - -q -t 1 http://project/cron/tutor_activities.php)"
Process substitution runs the command within <() and puts the output into a file object that is only visible from the current process. In order to use it from cron, invoke bash directly and pass it as a command string.
And as others have mentioned, use the full path to php which you can find out with which php.
I'm trying to get a cron job to run every 5 min on my localhost. Using the Cronnix app I entered the following command
0,5 * * * * root curl http://localhost:8888/site/ > /dev/null
The script runs fine when I visit http://localhost:8888/site/ in my browser. I've read some stuff about getting CI to run on Cron, using wget and various other options but none make a lot of sense.
In another SO post I found the following command
wget -O - -q -t 1 http://www.example.com/cron/run
What is the "-O - -q -t 1" syntax exactly?
Are there other options?
-O - Means the output goes to stdout (-O /dev/null) would nullify any output. -q means be quiet (don't print out any progress bars), this would screw up the look of any log files. -t 1 means to only try once. If the connection fails or times out it will not try again.
See http://linux.die.net/man/1/wget for a full manual on the wget command.
Edit: just realised you're piping all this to /dev/null anyway, you may as well either omit the -O parameter or point that to /dev/null and omit the final pipe.
What I always do is use PHP in cli mode. Seems more efficient to me.
first setup a cron entry like :
*/5 * * * * /usr/bin/php /var/www/html/cronnedscript.php
cronnedscript.php should be placed in your root www folder.
then edit cronnedscript.php with:
<?php
$_GET["/mycontroller/index"] = null;
require "index.php";
?>
where mycrontroller is the CI controller you want to fire.
if you want the controller to only be run by crond ,as opposed through public www requests, add the following line to the controller and to the cronnedscript.php :
if (isset($_SERVER['REMOTE_ADDR'])) die('Permission denied');
I realize that this is a reference to Drupal, however they do a very nice job of explaining what each and every parameter is in the wget call.
Drupal Cron Explanation
If you want the more generic explanation, you can find it here.
Try this and save it by making a folder in the C drive with a .bat extension.
Then give the path of this script to task scheduler.
Then run the same.
