body: <p>I am currently facing an issue. When I am executing command (<code>find /home/vivek36/ -name '*$indexnumber*.wav'  -exec cp {} /home/main/backup \;</code>) from terminal. then it executes. But when I am executing this command from <code>shell_exec()</code> in PHP, It does not execute.I am executing php script from root users. Any help would be appriciated.</p>
