I am trying to use shell_exec command in a php file.
shell_exec(date) works fine, but shell_exec(sudo date) is not working.
Is there any limitation with sudo command in shell_exec?

when using sudo in shell_exec, following msg is shown in the brwoser: 'sudo: no tty present and no askpass program specified' – Rkumar May 10 '15 at 05:41

Don't use `sudo`. Give proper permissions to resources so that the web server can execute the commands without `sudo` – hek2mgl May 10 '15 at 05:57

TTY settings can be altered in sudoers. – Devon Bessemer May 10 '15 at 06:51
