BAT is a Windows batch script - a plain-text file of MS-DOS / Command Prompt commands run in sequence to automate tasks on Windows. The .bat extension dates back to MS-DOS in 1981; .cmd was added with Windows NT and behaves almost identically. Analyser handles .BAT alongside related formats such as .HTML, .CSS, .JS and more. In Analyser's format library, .BAT sits in the Data & code category.
