The first and only user that exists on a new installation is called root. You use the root account to log in and create secondary “normal” users. After this initial interaction, you are expected to log in as a normal user. Running your system as a normal user is a self-imposed restriction that protects you from making stupid mistakes.
Steps to check sudo Command Usage on Linux
Authentication Log
sudo ls -l /var/log/sudo This will give you a list of all the files and folders in the directory ‘/var/log/sudo’. You can then use the grep command to search for specific information. For example, if you want to find out who ran the sudo command on your system on Tue Jul 10 08:12:01 BST 2014, you would use the grep command as follows: grep sudo Thu Jul 12 08:12:01 BST 2014 This will give you a list of all files and folders that contain the word ‘sudo’.
If you are using a distribution that uses a different location for the log file, you can check it by running the following command: sudo ls -l /var/log/secure | grep audit
Making Sense of Chaos
The log file will contain a lot of entries that are probably not of interest. You can browse and scroll through it or use the search function of your text editor to find any use of sudo.
grep -i “sudo” /var/log/sudo Step 2: If you want to find all sudo entries in a specific directory, use the following command: ls -l /var/log/sudo
If you are using a distribution other than Ubuntu, remember to update the path to the log file in your /etc/logrotate.d directory. ..
-e “C:\Users\username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup”
-R “C:\Users\username\AppData\Roaming\Microsoft \Windows \Start Menu\Programs\Startup”
When you check out the computer, you’ll find a series of entries that contain the date, time, computer name, and command used.
Normal Bash
ls -l This would list the contents of the “.bash_history” file in the Home folder.
To run the commands in the terminal, type: ls -l or cd /usr/local/bin
Journalctl
Step 2: To start sudo, type the following command in a terminal: sudo systemctl start sudo systemctl enable sudo journalctl Step 3: To view the contents of the sudo journal, type the following command: journalctl -u
Journalctl is a tool that can be used to track the state of your Linux system. This tool can be helpful if you are constantly switching between different Linux distributions.
To view the sudo logs, you first need to log in as either the root user or an account with superuser privileges. To do this, you can use the following command: journalctl -u root journalctl -s sudo
sudo logs -l
GUI-specific Programs
If they are not, you can install them using the package manager. For Debian and Ubuntu systems, this is aptitude or synaptic. For Fedora and CentOS systems, it is yum or apt-get.
GNOME Log
GNOME Log is the default system logger for distributions that use the GNOME desktop environment. This includes Ubuntu 21.10, 22.04 as well as Fedora 36.
Step 2: The GNOME Log Utility can be found in the Application Menu. From there, you can type “Logs” to search for the GNOME Log Utility.
Once open, the program will present a number of tabs where you can check the log for a particular aspect of your system. To check for your sudo logs, you will need to click “Security”. ..
To get the latest security information for your machine, follow these steps: First, the system will print all of the recent processes that ran with root privileges. From here, you can use the Magnifying Glass icon on the top right corner of the window to search for any log entries related to security issues. ..
To hide all commands and processes run through sudo, type “sudo” at the command prompt.
Final Words
To review sudo Command Usage on Linux, we recommend using the following steps:
- Type sudo at the command prompt. This will start the sudo command.
- Type help at the command prompt to get more information about sudo.
- Type listsudo to see all of the sudo commands that are available on your system.
