Execute shell command with sudo?

[henryliuser]

I want to make use of shell_command but my script requires sudo. If i just prepend sudo it says

[error] [console_user_server] shell_command stderr:a password is required
[error] [console_user_server] shell_command stderr:sudo: a terminal is required to read the password; either use the -S option to read from standard input or configure an askpass helper

What's the right way to make this work?
