It is used on the 'echo off' command to prevent that first command from displaying the input and OFF The symbol prevents a command from having input and its prompt displayed. Typically, batch files start with the 'echo off' command, which stops the input and prompt from being displayed during execution, so only the command output is displayed.

When the end of the file is reached, the file exits to the Command Prompt if it was invoked from there, or the console window closes if it was invoked from Windows Explorer or the START command. cmd extension prevents mis-use in older environments.Įxecution starts at the top of the file and ends at the end. cmd files are only interpreted by the Command Prompt, so using the. bat is more recognisable, as it was used in the MS-DOS environment that preceded the Command Prompt, the Command Prompt's interpretations of batch files is very different to the manner of interpreting DOS batch files, and. The script is kept inside a batch file, with the extension.
In order to try to learn about batch files, it is useful to understand Command Prompt commands. Color settings, however, are retained on later editions of Windows NT. Although the batch files are able to manipulate their environment, such as color settings and environment variables, the changes are all temporary, as in a standard Command Prompt session. Batch files can be run from Windows Explorer but the console used to display them closes automatically at the end of the batch file, so a command at the end that prevents instantaneous exit is needed for any remaining output to be read before the console window closes. The file is controlled by a list of commands separated into lines which are run like normal commands would be at the Command Prompt, although some functionality is different. Batch file scripts are not case-sensitive, although strings and data are. The advantages of using batch files are the ease of writing them, the ability to edit the files without compiling anything, their cross-compatibility across Windows NT Operating Systems and their inherent ability to manipulate file systems due to their basis on MS-DOS. The batch files can be considered to be a simple scripting language with logic and jumps. They can be used to automate file-system tasks such as backups or basic installations and can be used with other command-line utilities as well.
In Windows NT (XP, Vista, 7, 8, 10.) one is able to write batch files that are interpreted by the Command Prompt (cmd.exe).
