What must be done after making changes in the CLI to ensure they are saved?

To ensure that changes made in the Command Line Interface (CLI) are saved, executing a commit command is essential. The commit command is utilized in version control systems, such as Git, to capture a snapshot of the changes you have made to the codebase. This step creates a new commit that includes your modifications, allowing these changes to be tracked and managed effectively.

When you perform a commit, it typically includes a message describing the changes, which helps document the development process. This step is crucial because, without committing the changes, they remain in the local working directory and are not officially recorded in the version history, risking loss of work if not properly saved.

While performing a push command sends committed changes to a remote repository, it is not necessary immediately after making changes locally. The version control feature provides tools for managing these changes but does not itself save them without a commit. A validation check is useful for ensuring code quality and integration but does not pertain to saving changes specifically. Therefore, executing a commit is the correct action to secure any modifications made in the CLI.
