Stop an already running cron job

I have a PHP script on server that sends newsletter emails to my site users using a cron job. The users list is approximately 55,000 and takes nine hours.

Is there any way to stop it (urgently)?

You need to get the PID of your running cron job and then perform simple kill command.

I wouldn't suggest allowing the use of system(), exec(), passthru(), etc. Its a security issue.

If you do have a control panel, there has to be a way to manage the cron jobs, and I believe with most of them you also have the ability to launch an SSH session. You could use this method to stop/start the running process.

Last but not least, if you can't stop it yourself, contact your host.

someone already wrote u the answer,

try:

1. ps -e | grep "php name file"

   the above command will display you the process id, so:

2. kill - 9 'process ID'
