What Is Sudo Command in Linux?
Sudo, an abbreviation for superuser do, is a program that allows users to run commands or programs with root or elevated privileges. Usually, using sudo is the recommended way to run a Linux system instead of using the root user. This mitigates the risk of breaking the system in case a potentially dangerous command is executed.
The sudo package ships by default in most Linux distributions, and you should not have a problem using it. However, this does not always apply to all Linux distributions. There are particular cases where the system does not come with sudo installed. This is especially true for older Debian systems such as Debian 10 and later.
The “sudo command not found” error is nothing to be worried about and in case you have encountered this error, worry not. You can address it in a few simple steps.
How to Fix “sudo command not found” in Linux
To fix this error, log into your system as the root user or simply switch to the root user.
$ sudo su -
Next, update the package lists and install the sudo package as follows.
# apt update -y # apt install sudo -y
If you are running an RHEL-based distribution such as CentOS Stream, Fedora or Rocky/Alma Linux switch to the root user.
# su -
Then install sudo using the yum command as shown.
# yum install sudo
For Arch Linux, run the command.
# pacman -Sy sudo
Add User to Sudo Group in Linux
From here, you can add users to the sudo group. For example, to add user tecmint to the sudo group, run the command.
# usermod -aG sudo tecmint
To confirm that the user has been added to the group, run:
# groups tecmint
From here, you can comfortably run commands using sudo without an issue at all.
# su tecmint $ whoami $ sudo apt install apache2

If you are a Linux user, you may have encountered the “-bash: sudo: command not found” error. This error occurs when the sudo command is not found in the system. The sudo command is used to run commands as the root user or another user. It is an important command for system administrators and users who need to perform administrative tasks.

Check if sudo is Installed
The first step is to check if sudo is installed on your system. To do this, open a terminal window and type the following command:

Check sudo Configuration
If sudo is installed, you should check the sudo configuration to make sure it is configured correctly. To do this, open the sudoers file in a text editor:
sudo nano /etc/sudoers
The sudoers file contains the configuration for sudo. Make sure that the user you are trying to run sudo as is listed in the file. If the user is not listed, you can add it by adding a line like this:

Replace “username” with the username of the user you want to be able to use sudo.
