I set up a cron job in Cpanel according to instructions from my CMS software but received this email alert:
/usr/local/cpanel/bin/jailshell: /usr/bin/wget: Permission denied

The cron I tried to run was:
wget --tries=1 --timeout=99999 -0 cron.txt

Hello BradCraw, and thanks for your question.

If you are trying to run a cron job on shared hosting, it's important to note that wget is disabled for security reasons.

You can instead utilize curl if you need to download a remote file, being sure to also define a user-agent so that it doesn't trip a ModSecurity error:

/usr/bin/curl --user-agent CronJob --retry 1 --max-time 60 -o cron.txt

Please let us know if you're still having any issues at all.

Thanks Jacob. I'll give it a shot. I copied everything you had exactly up to the URL so we'll see what happens. Would be nice if there was a way to run it now instead of having to wait for the scheduled time. Oh well. I'll report back tomorrow around noon. :-)

Hello BradCraw,

No problem at all. If you'd like to test out the script right away instead of waiting for the cron job to run. You could simply place this code in a file called something like crontest.php


exec ("/usr/bin/curl --user-agent CronJob --retry 1 --max-time 60 -o cron.txt");


Then you would just access that PHP script on your site like If you didn't receive any errors, then you should be able to access the output file at with the results of the remote file grab.

Please let us know if you had any other questions at all.

Thanks again Jacob. I received this error report this morning when it ran:
curl: Remote file name has no length!
curl: try 'curl --help' for more information

curl: (60) error setting certificate verify locations:
CAfile: /etc/pki/tls/certs/ca-bundle.crt
CApath: none

Do I need to do something special since my site has SSL? I think I'm just going to upgrade to VPS account for this and other reasons. But thought I would post this for anyone else with problems.

Hello again BradCraw,

It looks like you just left over the syntax for wget using -O cron.txt which isn't a command in curl. You instead want to use a lowercase -o cron.txt.

I've gone ahead and made this adjustment in your cron job for you.

Also it doesn't look like there is anything at the URL you are trying to request from, you'll want to make sure that there is actual content at the URL you're trying to have curl request from, otherwise you won't end up with any output in your cron.txt file.

Connecting to a site with an SSL certificate shouldn't matter, I believe you were just getting the SSL error because it didn't understand the -O flag you were passing to the command.

Please let us know if you're still having any issues at all.

It worked. I tested it using the PHP exec method you gave me and after you changed the capitol O to lowercase, it ran without error. I logged into my CMS and it does show that it ran with no errors. There must be some sort of redirect because the folder the cron.txt file is supposed to be located in doesn't even exist. But it works so I'll happy. Thanks Jacob. You've been very helpful.

Hello again BradCraw,

Glad to hear that's working now! When you specify the output file as just -o cron.txt in your cron job. This file should be placed in your main home directory at /home/userna5/cron.txt.

You could also enter in a full path if you wanted it to be available from your website like -o /home/userna5/public_html/cron.txt which you could then access from

Please let us know if you had any other questions at all!
