The new operating system, Windows 10, introduces a new feature called “sudo.” This allows a user to run a command with the same permissions as other users, such as the superuser. This is equivalent to the “run as administrator” option in Windows. Multiple administrators can be created thanks to the sudo option, and access control is the most important of the many operating system concepts. Policies governing access control ensure that no user is allowed to perform tasks for which they have not been granted permission. ..

The root user and the regular user are the two most common user types on all operating systems. Even a guest user occasionally needs to perform operations that require administrator rights. Fortunately, Linux gives us a mechanism to do this, namely using the keyword “sudo” before a command. Because it’s such a magic keyword, each command that follows can be run with root privileges instead of its own restricted rights. We have mentioned below the steps to use sudo command in Linux. ..

Steps to use sudo command on Linux

Updating your system with the sudo command

To refresh your system cache on a Linux system, you must first run the update command with the privileges of a root user. This is because sometimes some existing packages are not fixed which can cause problems when you install something new on your system. ..

Step 2: Type the following command to start a new terminal: sudo nano /etc/profile Step 3: Change the following line to read as follows: export PS1=’[\033[01;31m’ Step 4: Save and close the nano file. Now, type the following command to start a new terminal on Debian GNU/Linux systems: sudo apt-get install nano

sudo update Step 3: After running the “update” command, you will need to reboot your computer in order for the changes to take effect. To do this, type the following command into the terminal: reboot ..

When you press the Enter key, the “update” will take a few seconds to complete its execution, depending on how many packages are to be updated. The more packages or dependencies that are broken or out of date, the longer it will take to run the “update” command. ..

Updating your system with the sudo command

To upgrade the packages on your system, you must run the “upgrade” command with “sudo” privileges.

sudo apt-get update Step 2: In your Linux Mint 20 Terminal you must run the following command: sudo apt-get install python3 python3-pip Step 3: In your Linux Mint 20 Terminal you must run the following command: sudo apt-get install build-essential libssl-dev libcrypto++5.0 libcurl4-openssl1.0 libcurl6-openssl1.0

If you want to proceed with the installation, type “Y” and press Enter. If you don’t want to update your packages, type “N” and press Enter. ..

Step 3: The update will take a few minutes to complete, depending on the number of packages that need updating. ..

Creating a text file with the sudo command

  1. Log in to your Linux system as the root user.
  2. Type the following command to create a new text file: sudo nano myfile.txt
  3. Enter the following content into the file:
  4. Save the file by pressing Ctrl-X and then Y to exit the editor.

git clone https://github.com/apache/commons-lang3 Step 2: In the cloned repository, you will find a file called “commons-lang3.git” which contains the source code for the commons-lang3 library. Step 3: To build and install commons-lang3, you will need to use the following command: git clone https://github.com/apache/commons-lang3 cd commons-lang3 make

Step 2: You can replace “MyFile.txt” with any name of your choice for your text file instead of naming it MyFile.txt. As in this case, we named our text file sudo.txt.

After running this command, it will create a new empty text file with the name specified in your Home directory, and will also open that file with the nano editor from where you can add any content of your choice to this file.

To save your work, press Ctrl+X to exit nano and then type Y to confirm the save. If you want to check if your text file was actually created on your Home directory, you can run the “sudo” command or use the ls -l command. ..

Final Words

To use sudo on a Linux system, you must first create a new user account called “root” and then log in as that user. After logging in as root, you will need to use the sudo command to change your password. You can also use sudo to change your default shell or to set up security features for your system.
