11/25/2023 0 Comments Su vs sudo![]() ![]() In addition, most sh scripts can be run by Bash without modification. Critically, the significant way sudo su and su differ comes down to which password we need to enter. It offers functional improvements over sh for both programming and interactive use. Modern Linux distributions preconfigure the first user to be able to sudo with her own password. However, you can setup sudo so that ordinary users can achieve root privileges with their own password by modifying /etc/sudoers (as root, preferably with visudo ). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. 6 Answers Sorted by: 7 The su (and sudo) command traditionally require root 's password. 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. But both the commands directs me to the root terminal. And when I type just su It asks for the root user password. :) When I type sudo su It asks for my user password. This command is used to login at root account.īy default, the Root account password is locked in Ubuntu. 11 This question already has answers here : What are the differences between 'su', 'sudo -s', 'sudo -i', 'sudo su' (6 answers) Closed 8 years ago. ![]() In some cases, this is necessarily Root, but most of the time it is a regular user. ![]() You have to call sudo with root privileges: sudo su. Therefore you cannot switch to the root user with su (you can try). Ideally, you run as a user that has only the privileges needed for the task at hand. But, in most modern (desktop-) Linux distributions (for example Ubuntu) the root user is disabled and has no password set. When any superuser type su, it will prompt to enter the root. What is ‘su’ command ‘su’ commands forces you to share your root password to other users. In this article we will discuss what is the main difference between su and sudo commands. You could type a command incorrectly and destroy the system. For the most Linux distributions, su and sudo are widely used commands. The SuperUser can do anything and everything, and thus doing daily work as the SuperUser can be dangerous. In Linux (and Unix in general), there is a SuperUser named Root. ![]()
