NAME sudo_root - How to run administrative commands SYNOPSIS sudo command sudo -i INTRODUCTION By default,the password for the user "root" (the system administrator) is locked. This means you cannot login as root or use su. Instead,the installer will set up sudo to allow the user that is created during install to run all administrative commands. This means that in the terminal you can use sudo for commands that require root privileges. All programs in the menu will use a graphical sudo to prompt for a password. When sudo asks for a password,it needs your password,this means that a root password is not needed. To run a command which requires root privileges in a terminal,simply prepend sudo in front of it. To get an interactive root shell,use sudo -i. ALLOWING OTHER USERS TO RUN SUDO By default,only the user who installed the system is permitted to run sudo. To add more administrators,i. e. users who can run sudo,you have to add these users to the group 'sudo' by doing one of the following steps: * In a shell,do sudo adduser username sudo * Use the graphical "Users & Groups" program in the "System settings" menu to add the new user to the sudo group. @H_403_3@
