In this tutorial, we will guide you through the process of removing the sudo note from the terminal in Ubuntu. This note typically appears when you open the terminal and can be a bit of an annoyance for some users. Let’s dive into the process.
To remove the sudo note from the terminal in Ubuntu, you have a few options. You can run a sudo command, create the ~/.sudo_as_admin_successful file manually, or delete the file if you want to bring back the sudo note. If you want to remove this functionality permanently, you can edit the /etc/bash.bashrc file and remove the section that displays the message. However, be cautious when modifying system files and always make backups before making any changes.
What is the Sudo Note?
When you open the terminal in Ubuntu, you might see a message like this:
To run a command as administrator (user 'root'), use "sudo <command>".
See "man sudo_root" for details.This is the sudo note, a helpful reminder for new users on how to execute commands with root privileges. However, for more experienced users, this message can be unnecessary and repetitive.
Method 1: Running a Sudo Command
The simplest way to remove the sudo note is by running a sudo command. For example:
sudo apt-get updateThis command updates the list of available packages and their versions, but it does not install or upgrade any packages. The sudo before the command means it will be executed with root privileges.
When you run a sudo command, Ubuntu creates a file named ~/.sudo_as_admin_successful. After this file is created, the sudo note will no longer appear.
Method 2: Creating the File Manually
If you don’t want to run a sudo command, you can create the ~/.sudo_as_admin_successful file manually. Use the touch command to do this:
touch ~/.sudo_as_admin_successfulThe touch command is used to create a new file. In this case, it creates the ~/.sudo_as_admin_successful file.
Method 3: Removing the File
If you want to bring back the sudo note, you can remove the ~/.sudo_as_admin_successful file. Use the rm command to do this:
rm ~/.sudo_as_admin_successfulThe rm command is used to remove files. In this case, it removes the ~/.sudo_as_admin_successful file.
Method 4: Removing the Functionality Completely
If you want to remove this functionality permanently, you can edit the /etc/bash.bashrc file and remove the section that displays the message. Use the nano command to open the file:
sudo nano /etc/bash.bashrcFind the following section:
if [ ! -e "$HOME/.sudo_as_admin_successful" ] && [ ! -e "$HOME/.hushlogin" ] ; then
case " $(groups) " in *\ admin\ *)
if [ -x /usr/bin/sudo ]; then
cat <<-EOF
To run a command as administrator (user 'root'), use "sudo <command>".
See "man sudo_root" for details.
EOF

esac
fiYou can comment out this section by adding a # at the beginning of each line, or you can delete it entirely. After you’re done, press Ctrl+X to exit, and Y to save the changes.
Please note that modifying system files can have serious consequences if not done correctly. Always make sure to create backups before making any changes.
