I've been running a simple php script (which logs its running time in a text log file). From browser it runs fine, but as I use the scheduled tasks in my plesk 10.3.1 panel as follow:
*/5 * * * * php /var/www/vhosts/eblogs.co.uk/httpdocs/frostbox/cron/crone_test.php
It does run right after five minutes but does not write anything in the text file and sends me following notification messages via email:
php [-f from_encoding] [-t to_encoding] [-s string] [files...]
php -l
php -r encoding_alias
-l,--list
lists all available encodings
-r,--resolve encoding_alias
resolve encoding to its (Encode) canonical name
-f,--from from_encoding
when omitted, the current locale will be used
-t,--to to_encoding
when omitted, the current locale will be used
-s,--string string
"string" will be the input instead of STDIN or files
The following are mainly of interest to Encode hackers:
-D,--debug show debug information
-C N | -c | -p check the validity of the input
-S,--scheme scheme use the scheme for conversion
What should I add in the following line?
php /var/www/vhosts/eblogs.co.uk/httpdocs/frostbox/cron/crone_test.php
The text you get back is the usage message of piconv. This has absolutely nothing to do with PHP, the scripting language. What you probably want to do is one of the following:
Alternative 1: Using the PHP command line interpreter
You need to call the actual php interpreter on your system. This might be /usr/bin/php5, so your crontab line would look like
*/5 * * * * /usr/bin/php5 /var/www/vhosts/eblogs.co.uk/httpdocs/frostbox/cron/crone_test.php
However not every setup has this command line interpreter installed. It might happen that only the apache module is installed.
Alternative 2: Using an HTTP(S) request
If you don't have the right to install the command line tool, have a look if wget or curl is installed. If so, you can use them to invoke the script by sending a request to the web server.
Using wget:
/usr/bin/wget -O /dev/null 'http://eblogs.co.uk/crone_test.php'
-O /dev/null tells it to save the web page generated by your script in /dev/null. It is a special file that basically immediately forgets all data written to it. So this parameter avoids that any new file with the web page contents is created and lies around in your server's file system.
Using curl:
/usr/bin/curl -o /dev/null 'http://eblogs.co.uk/crone_test.php'
-o /dev/null has the same function here as the version with the capital O above for wget.
Add the following at the top of the php script:
#!/usr/bin/php
<?php
your code here
?>
(assuming php exists at /usr/bin)
Hope that helps !
You can use "curl" ... like this:
curl "http://eblogs.co.uk/crone_test.php"

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 have a simply php script on my server and want it to be run every 2 minutes using a cron job.
*/2 * * * * http://mydomain.com/_adder.php
I suspect the command syntax is wrong.
Do I need to add a command before the script url? Another way to run the script?
Any help is very much appreciated.
the cron-job will simply execute a program on the (local) machine.
a URL is NOT a program. it's a link to a ressource.
whether this ressource triggers a PHP-script execution is not of cron's business.
in any case, you could run a cron-job that will periodically visit a given URL. e.g. using the wget command (a "non-interactive web-page downloader")
*/2 * * * * wget --quiet -O /dev/null http://mydomain.com/_adder.php
you can do it as umläute suggest, but being a local file it's actually faster to access from command line php like this:
*/2 * * * * php /path/to/file/_adder.php
there are differences running a script from the command line vs via a browser that may effect the script.
you may need the full path to php on some systems
use php-cgi to make GET request similar to a web browser .
/usr/bin/php-cgi /your_path/_adder.php
if you're using Linux you can use which php-cgi to locate for php-cgi or search for php7.2-cgi if php 7.2 installed on your machine or search using different version . for Windows users search for php-cgi.exe .
I would like to execute a cronjob for a routine task every X hours. The cronjob basically executes a shell script which in turn uses a WGET command to download files from a remote server. However, before I run this shell script I want the cronjob to execute a php script which will check whether the update's available (there's no point in wasting BW and downloading the same file over and over again) and if it is, it should pass on the update URL to the shell script which in turn uses the WGET command.
The cronjobs are set from the hosts Admin Panel. There is no other way around it. Being a shared hosting service, I am not allowed access to other functions on PHP which might do the task for me either.
Is this possible? I am Linux illiterate. I have installed a few RPM's on Fedora but that's about it. Please bear with me. Thanks!
Just pass --timestamping to your wget command.
Alternatively if you are more familiar with PHP's ways you can check this question for a usable method.
Use a curl HEAD request to get the file's headers and parse out the Last-Modified: header.
To use a php script as a regular command line executable use this as a starting point:
#!/bin/env php
<?php
echo "Hello World\n";
Save the file without the .php and tuck it somewhere that your server won't serve it.
Next, set the executable bit so that you can execute the script like a regular program
(u+x in the following command means grant the [u]ser e[x]ecute privileges for helloworld, and chmod is the command that unix variants use to set file permissions)
Omit the $ in the following sequence, as it represents the command prompt
$ chmod u+x helloworld
now you can execute your commandline script by calling it in the bash prompt:
$ ls
helloworld
$ ./helloworld
Hello World
$
From here you can get the full path of the executable script:
$ readlink -f helloworld
/home/SPI/helloworld
And now you can install the cronjob using the path to your executable script.
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'
Resolving project... IP Address

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,
Sandeepan
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.
