Let considered an example and provide ALL power to userA as root. So, root has all the privileges to run any command as any user or group. This allows root to run any command anywhere.Meaning of this line is – username hosts=(users:groups) commandsĪLL means, the user can run all commands on all hosts, as all users and groups. Syntax of pre-defined rule is given below – root ALL=(ALL:ALL) ALL

If it identifies any error, then visudo won’t allow to save the file with edits.Ī common question arises in everyone’s mind, how we define the rules in sudoers file? So, before editing it’s better to understand the existing configuration which defines which users can run what software on which machines. It also checks the syntax of edits and provide basic sanity checks which are very helpful. Visudo: /etc/sudoers busy, try again later Visudo command cannot allow to edit /etc/sudoers file simultaneously by just locking the file and if someone tries to access the same it will get a message to try ~]# visudo Editing /etc/sudoers file requires superuser’s privileges. Visudo is a command to edit configuration file for sudo command located at /etc/sudoers.You should not edit this file directly with normal editor, always use visudo for safety and security. Before describing “sudo” command I want to talk a bit about visudo These information are defined in the /etc/sudoers file. It allows a user to run a command as a root or as any other user after providing the user’s own password for authentication. To overcome above mentioned risk, sudo command comes in trend. It’s asking for the password of superuser. In corporate world this is very dangerous because all the privileges of root are granted to any user, who can do anything. The easy and common way to grant administrative privileges to non-root users is, a user can use su command and temporarily become the root but users must know the root’s password. To run any command, they need to ask for permissions from the superuser. A root user can do anything but normal user has no permissions. Linux follows the very tough permission model.
