This command works :

        shell_exec('sudo -u root -S /home/jon/reboot.sh < /home/jon/pwd');

The system reboot as expected.

But this fails:

        shell_exec('sudo -u root -S /home/jon/reboot.sh < /tmp/Csikea');

Why does using a tmp file fail ? it contains the same password as the pwd file.

The apache log shows : sudo: pam_authenticate: Conversation error

I've manually set the owner and permissions on Csikea to be the same as pwd Still have the same issue.

Any ideas ?

Thanks

Thanks that link gave me this: `system('echo "PASS" | sudo -u root -S COMMAND');` which works even better. – Rocket Sep 11 '14 at 14:16
