Updating security patches in Linux using the command line interface (CLI) typically involves using the package manager specific to your distribution. Here are the general steps to update security patches in Linux using the CLI:
- Log in to your Linux system as the root user or as a user with
sudoprivileges. - Open a terminal window.
- Update the package manager’s repository information using the appropriate command for your distribution. For example, on Ubuntu and Debian-based systems, you can run the following command:
sudo apt-get update
On Red Hat and CentOS-based systems, you can use the following command:
sudo yum updateinfo
- Once the repository information is updated, you can update all installed packages to their latest versions, including security patches, by running the appropriate command for your distribution. For example, on Ubuntu and Debian-based systems, you can run the following command:
sudo apt-get upgrade
On Red Hat and CentOS-based systems, you can use the following command:
sudo yum update
- During the package update process, you may be prompted to confirm the update or to choose how to handle conflicts or other issues. Follow the prompts and enter any necessary information to complete the update process.
- Once the update process is complete, you can check the version of the installed packages to confirm that the latest security patches have been applied. For example, on Ubuntu and Debian-based systems, you can run the following command to check the version of the OpenSSH package:
ssh -V
On Red Hat and CentOS-based systems, you can use the following command:
rpm -q openssh
Note that the specific commands and package names may differ depending on your distribution and version. Be sure to consult the documentation for your specific distribution for the appropriate commands and options. Additionally, it is important to regularly update your system to ensure that it is secure and up-to-date.
