You can use the command shell to create and edit batch files (also called scripts) to automate routine tasks. For example, you can use scripts to automate the management of user accounts or nightly backups. You can also use the Windows Script Host, CScript.exe, to run more sophisticated scripts in the command shell. You can perform operations more efficiently by using batch files than you can by using the user interface. Batch files accept all commands that are available at the command line.
