Depending on your settings in the /etc/sudoers file, you can issue single commands as root or as another user. It offers functional improvements over sh for both programming and interactive use. sudo, which is an acronym for superuser do or substitute user do, is a command that runs an elevated prompt without a need to change your identity. It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). This command runs "bash" as a super user.īash is the shell, or command language interpreter. The sh utility is a command language interpreter that shall execute commands read from a command line string, the standard input, or a specified file. This is where sudo comes in - it allows authorized users (normally "Administrative" users) to run certain programs as Root without having to know the root password. However, since the Root account physically exists it is still possible to run programs with root-level privileges. ![]() This means that you cannot login as Root directly or use the su command to become the Root user. Sudo y Su proporcionan privilegios de root de dos maneras diferentes que en este artculo te voy a explicar. Si eres un novato en Linux, quedars fascinado con las maravillas que puedes hacer usando los comandos Sudo y Su. This command is used to login at root account.īy default, the Root account password is locked in Ubuntu. Todo buen usuario de GNU/Linux utiliza con frecuencia la terminal. In some cases, this is necessarily Root, but most of the time it is a regular user. Ideally, you run as a user that has only the privileges needed for the task at hand. You could type a command incorrectly and destroy the system. If you have sudo privileges with no password, then you will not be prompted for a password and instead will be logged into root immediately. Sudo, short for superuser do, is a command that allows a user to execute a command as another user by entering their own password. The difference between sudo su - and su - is this: With sudo su - you will be asked to authenticate with your user password (assuming you have sudo privileges). The SuperUser can do anything and everything, and thus doing daily work as the SuperUser can be dangerous. su, short for switch user, is a command that allows a user to switch to another user account, the root account, by entering the target user’s password. In Linux (and Unix in general), there is a SuperUser named Root.
