Allow any user on linux to run smartctl without password

Need to have a script or external application run smartctl without being prompted for a password? Simply add it to the sudoers file. Under Ubuntu/Debian use “visudo” to edit it (DO NOT EDIT IT WITHOUT USING THIS COMMAND!) and add the following line:

ALL ALL=(ALL)NOPASSWD: /usr/sbin/smartctl

This allows any user, from any source (local or remote) to run the smartctl command without being prompted for a password. Note, your script or user will still need to preface the smartctl command with sudo.
