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.
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 ...
AUTOEXEC.BAT is a system file that was originally on DOS-type operating systems.It is a plain-text batch file in the root directory of the boot device.The name of the file is an abbreviation of "automatic execution", which describes its function in automatically executing commands on system startup; the filename was coined in response to the 8.3 filename limitations of the FAT file system family.
EDIT is a full-screen text editor, included with MS-DOS versions 5 and 6, [1] OS/2 and Windows NT to 4.0 The corresponding program in Windows 95 and later, and Windows 2000 and later is Edit v2.0. PC DOS 6 and later use the DOS E Editor and DR-DOS used editor up to version 7.
COMMAND.COM is the default command-line interpreter for MS-DOS, Windows 95, Windows 98 and Windows Me.In the case of DOS, it is the default user interface as well. [2] It has an additional role as the usual first program run after boot (init process), hence being responsible for setting up the system by running the AUTOEXEC.BAT configuration file, and being the ancestor of all processes.
Under OS/2 and Windows NT, the .CMD file extension is associated with batch scripts for their command processor CMD.EXE.Since binary code will not be executed this way, attempting to run CP/M-86 CMD files under the CMD command processor will not work, but typically only cause mild inconvenience to users.
This was a plain text file with simple key–value pairs (e.g. DEVICEHIGH=C:\\DOS\\ANSI.SYS) until MS-DOS 6, which introduced an INI-file style format. There was also a standard plain text batch file named AUTOEXEC.BAT that ran a series of commands on boot. Both these files were retained up to Windows 98SE, which still ran on top of MS-DOS.
A batch window is "a period of less-intensive online activity", [11] when the computer system is able to run batch jobs without interference from, or with, interactive online systems. A bank's end-of-day (EOD) jobs require the concept of cutover , where transaction and data are cut off for a particular day's batch activity ("deposits after 3 PM ...
