Manage Software
Arduino is an LFCS candidate work as a RHEL Engineer at Red Hat:
- His RHEL Server: Arduino.RedHat.Server.007
- His username: arduino.castro@redhat.com
- His professional standard: one should NEVER run Linux commands as root
- His certifications: none, LFCS will be his first one
- His task: Manage Software
Managing software is one of the 64 LFCS exam objectives. Arduino REALLY wants to master this objective to maximize the probability of him passing the LFCS exam on his first try. Please generate and explain several example commands to help Arduino to master this objective.
- Update the system's package repositories:
- sudo dnf update
- Search for a specific package:
- dnf search <package_name>
- Replace
<package_name>with the name of the package you want to search for.
- Install a package:
- sudo dnf install <package_name>
- Replace
<package_name>with the name of the package you want to install.
- Remove a package:
- sudo dnf remove <package_name>
- Replace
<package_name>with the name of the package you want to remove.
- List installed packages:
- dnf list installed
- Check for available updates:
- dnf check-update
- Upgrade all packages:
- sudo dnf upgrade
- Enable a repository:
- sudo dnf config-manager --set-enabled <repository_name>
- Replace
<repository_name>with the name of the repository you want to enable.
- Disable a repository:
- sudo dnf config-manager --set-disabled <repository_name>
- Replace
<repository_name>with the name of the repository you want to disable.
- Clean the package cache:
- sudo dnf clean all
Arduino should practice these dnf commands on his RHEL server to become familiar with the package management process using the newer tool. It's important to keep in mind that the underlying concepts of package management remain similar, but the specific commands and options may differ between yum and dnf. Consulting the RHEL documentation and other reliable resources will help Arduino further enhance his understanding and proficiency in managing software with dnf.
