A Batch file (.bat) is a script file used in DOS, OS/2, and Microsoft Windows. It consists of a series of commands to be executed by the command-line interpreter (cmd.exe). Batch files are commonly used to automate routine tasks such as file backups, system configuration changes, and launching programs. Despite being an older technology, they remain relevant for system administration in Windows environments. Batch file samples are used to test Windows command-line utilities and task schedulers. System administrators rely on them to verify that automated maintenance tasks execute without errors. These files are also useful for testing antivirus software, as they ensure that benign automation scripts are not mistakenly flagged as malicious, and for validating legacy system compatibility.
