I am running a php script using the cPanel Cron Jobs. The script is using shell_exec to convert a video using ffmpeg. It executes the script and everything is working but it is not sending me the email. I am basically trying to get the output of the shell_exec to start another function in the php script so I wanted to send my self the email to make sure I am getting the output.

For example I wrote:

$command = "ffmpeg -i $og_video -b 1500k -vcodec libx264 -vpre slow -vpre baseline -g 30 $mp4_video";

//EXECUTE THE CONVERSION
$output = shell_exec($command);
echo $output;

I also tested the email by removing the shell_exec and just echo the $command variable. This will send me the full string in an email.

What I am trying to accomplish is basically if the shell_exec executed then do something else.

How do I check if the shell_exec was completed?

don't use shell_exec(), then. use [exec()](http://php.net/manual/en/function.exec.php), which gives you output AND the exit value of the executed program. – Marc B Jul 21 '15 at 21:05
Use a database/logging system or sth like http://gearman.org/ – Jan Jul 21 '15 at 21:07
How long it takes to exec the script ? – midan888 Jul 21 '15 at 21:07
When it completes it will execute the next line. – AbraCadaver Jul 21 '15 at 21:10
@midan888 depends on the file size. – iamthestreets Jul 21 '15 at 21:16
@AbraCadaver will it execute the next line if it errors or will it stop? – iamthestreets Jul 21 '15 at 21:16
Why was the answer removed? The answer to the linked post worked for me. I was able to echo the results of the `exec` command and it emailed me the results so based on the answer in the other question this will work for me. – iamthestreets Jul 21 '15 at 21:22
@iamthestreets if the script takes too long it might be killed on half way, depends on configuration, check this function, maybe its because of that, http://php.net/manual/en/function.set-time-limit.php – midan888 Jul 23 '15 at 06:21
you can use `nohup` and execute the command in background and check `PID` for completing the command. – علیرضا Nov 18 '17 at 04:53
