What is a .CMD file?
CMD is a Windows command script - the same idea as a .bat file but interpreted by the newer Windows NT command processor (cmd.exe), with a few extra features.
- Did you know
- Windows NT adopted .cmd in 1993 to distinguish its scripts from legacy MS-DOS .bat files that ran under COMMAND.COM, having inherited the extension from OS/2.
- The .cmd extension was introduced with Windows NT to distinguish scripts meant for the newer cmd.exe from legacy DOS .bat files.
- Functionally .bat and .cmd are nearly identical, with .cmd handling a few error-level and command behaviours more consistently.
- What Analyser shows you
- Preview and inspect HTML, CSS, JavaScript, TypeScript, JSON, YAML, XML and Markdown source files, plus Windows scripts. TypeScript (TS, MTS, and .d.ts declaration files) gets a structure readout beside the source: the modules it imports (packages against local files, and which are type-only), the names it exports, what it declares - interfaces, type aliases, enums, classes, functions - a code/comment/blank line breakdown, and how often it steps around the type system with any, as casts, non-null assertions and @ts- suppressions. PowerShell (PS1, PSM1, PSD1) is read for its comment-based help synopsis, #Requires directives, function and parameter counts, CmdletBinding and Authenticode signing; batch/command scripts (BAT, CMD) for the echo state, labels, variables set and the external tools they invoke.
- Open a .CMD file
- Drag a .CMD file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
