A batch file may contain any command the interpreter accepts interactively and use constructs that enable conditional branching and looping within the batch file, such as IF, FOR, and GOTO labels. The term "batch" is from batch processing, meaning "non-interactive execution", though a batch file might not process a batch of multiple data.
Traditionally batch files begin with the @echo off statement. This says to the interpreter that echoing of commands should be off during the whole execution of the batch file, thus resulting in a "tidier" output (the @ symbol declares that this particular command (echo off) should also be executed without echo.)
The batch size refers to the number of work units to be processed within one batch operation. Some examples are: The number of lines from a file to load into a database before committing the transaction. The number of messages to dequeue from a queue. The number of requests to send within one payload.
Alternatively, under Multiuser DOS and DR-DOS 7.02 and higher, various internal and external commands support a parameter /B (for "Batch"). [5] This modifies the output of commands to become suitable for direct command line input (when redirecting it into a batch file) or usage as a parameter for other commands (using it as input for another ...

Batch renaming is a form of batch processing used to rename multiple computer files and folders in an automated fashion, in order to save time and reduce the amount of work involved. Some sort of software is required to do this.
A CMD file has a 128-byte header, followed by 1–8 groups of code or data. [2] Each group can be up to 1 megabyte in size. In later versions of the format, CMD files can also contain relocation information and Resident System Extensions (RSXs). [2] The start of the header lists the groups present in the file, and their types.
