Microsoft released a version of cmd.exe for Windows 9x and ME called WIN95CMD to allow users of older versions of Windows to use certain cmd.exe-style batch files. As of Windows 8, cmd.exe is the normal command interpreter for batch files; the older COMMAND.COM can be run as well in 32-bit versions of Windows able to run 16-bit programs.
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 ...
A batch file is a script file in DOS, OS/2 and Microsoft Windows. It consists of a series of commands to be executed by the command-line interpreter , stored in a plain text file. A batch file may contain any command the interpreter accepts interactively and use constructs that enable conditional branching and looping within the batch file ...
In computing, start is a command of the IBM OS/2, [1] Microsoft Windows [2] and ReactOS [3] command-line interpreter cmd.exe [4] (and some versions of COMMAND.COM) to start programs or batch files or to open files or directories using the default program. start is not available as a standalone program.
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.
If the date argument begins with a minus (-), only files modified on or before the given date are selected (older file / modified earlier). Otherwise, only files modified on or after the given date are selected (younger files / modified later). An explicit plus (+) may be given, but is the default. Note that both modes select files on the given ...
Changes made to the command line environment after SetLocal commands are local to the batch file. EndLocal command restores the previous settings. [17] The Call command allows subroutines within batch file. The Call command in COMMAND.COM only supports calling external batch files. File name parser extensions to the Set command are comparable ...
Note that executing cd from the command line with no arguments has different effects in different operating systems. For example, if cd is executed without arguments in DOS, OS/2, or Windows, the current working directory is displayed (equivalent to Unix pwd). If cd is executed without arguments in Unix, the user is returned to the home directory.
