Assess your skills in CLI package management, exploring commands, dependency handling, and core ecosystem concepts. This quiz focuses on practical command-line scenarios to test your understanding of package installation, removal, updates, and repository management.
Which command installs the latest version of 'exampletool' globally using a typical CLI package manager?
Explanation: The correct command is 'install exampletool --global' as it installs the package globally, making it available system-wide. 'download exampletool --global' would only fetch the files without installing. 'get exampletool --all' is not a standard package installation syntax and may confuse package fetching with installation. 'deploy exampletool --add' refers to deployment, which is different from package installation. Only the first option aligns with typical CLI package manager commands.
When you want to update all installed packages to the latest versions, which action should you perform in the CLI?
Explanation: Choosing 'upgrade all' ensures that every installed package is updated to the newest versions available. 'remove all' would uninstall the packages, not update them. 'refresh only' typically reloads the metadata about packages without changing installed versions. 'fix all' could attempt repairs but does not guarantee package updates. Therefore, 'upgrade all' is the intended action for upgrading.
If installing a package called 'analytics' also results in the auto-installation of its required libraries, what is this process called in CLI package management?
Explanation: Dependency resolution refers to the process where the package manager automatically installs required libraries along with the main package. 'File extraction' is related to unpacking files but doesn't manage dependencies. 'Manual selection' would require the user to choose libraries explicitly rather than automating the process. 'Checksum verification' ensures data integrity, not dependency installation. The correct technical term is dependency resolution.
Which CLI command safely removes an installed package named 'legacytool' while also cleaning up any unused dependencies?
Explanation: 'remove legacytool --autoremove' uninstalls the specified package and also removes any dependencies no longer needed. 'erase legacytool --keep' suggests retaining files, which would not clean up dependencies. 'delete legacytool --retain' similarly implies keeping components rather than performing cleanup. 'clean legacytool --save' is not a recognized action for package removal. Only the first option handles both removal and cleanup effectively.
How do you add a new repository to your CLI package manager so that additional packages become available for installation?
Explanation: Using 'add-repo <repo-url>' incorporates the new repository into the package manager's sources, allowing access to more packages. 'list-repo <repo-url>' would likely just display known repositories, not add new ones. 'export-repo <repo-url>' suggests moving data out rather than importing a repository. 'scan-repo <repo-url>' may check repositories for updates but does not add them. Therefore, 'add-repo' is the correct choice.
