Batch filesīatch files have been around since the early days of MS-DOS, and have continued through the most recent Microsoft operating systems. One of the most noticeable differences when using the two shells is that does not support long filenames, thus forcing the use of constructs such as Progra~1 to address directories such as Program Files. is actually a version of 16-bit DOS running in a shell and provides a similar but not identical set of functionality. It is not a DOS shell, and does not provide the same functionality as such shells. CMD.exe is a text-based interface to the operating system. Ultimately, and CMD.exe are two different tools. In the newer 64-bit versions of these operating systems, is not available at the time of this writing, and may continue to be unavailable in the future. and CMD.exeĬ and CMD.exe are the two main shells available in most Microsoft operating systems. Even so, this leaves us with several choices when we need to put together scripts for Windows, including scripting with the standard command interpreters and PowerShell, as well as Cygwin or any other custom solutions we might find installed. On Microsoft operating systems, due to the generally closed nature of the operating system and standard applications and utilities present, we will often only find ourselves with access to the built-in text-based shells. Fortunately, Microsoft operating systems currently have a very well-developed and strong capability to conduct administrative operations from the command line and provide us with tools such as PowerShell to use in our efforts. As penetration testers, we would be foolish to ignore the scripting capabilities of this enormous share of the market. Microsoft operating systems hold 75 percent of the operating system market as of March 2011.
