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.
Control structures are mostly used inside batch files, although they can also be used interactively. [4] [3]:label Defines a target for GOTO. CALL Executes another batch file and returns to the old one and continues. FOR Iteration: repeats a command for each out of a specified set of files. GOTO Moves execution to a specified label.
Another important use of the echo command is to toggle echoing of commands on and off in batch files. 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 ...

Loops using while, repeat until or do, and for statements; switch a.k.a. case statements, a form of multiway branching; These new language mechanisms replaced equivalent flows which previously would have been written using gotos and ifs. Multi-way branching replaces the "computed goto" in which the instruction to jump to is determined ...
The file extension, double quoted, without leading dot. If a file has multiple extensions, only the last is returned. If the file has no extension, a quoted empty string is returned. @path Full path of the matching item, double quoted, including drive letter, and file extension (if any). @relpath
The term is also used more generally to mean the automated mode of running an operating system shell; each operating system uses a particular name for these functions including batch files (MSDos-Win95 stream, OS/2), command procedures (VMS), and shell scripts (Windows NT stream and third-party derivatives like 4NT—article is at cmd.exe), and ...
file.s is a command-line argument which tells the program rm to remove the file named file.s. Some programming languages, such as C, C++ and Java, allow a program to interpret the command-line arguments by handling them as string parameters in the main function.
