In MS-DOS, a batch file can be started from the command-line interface by typing its name, followed by any required parameters and pressing the ↵ Enter key. When DOS loads, the file AUTOEXEC.BAT, when present, is automatically executed, so any commands that need to be run to set up the DOS environment may be placed in this file.
Although a computer operator may be present, batch processing is intended to mostly operate without human intervention. Therefore, many details must be included in the submitted instructions: which programs to run; which files and/or devices to use for input/output; [2] under which conditions to skip a step.
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.
The console alternatives 4DOS, 4OS2, FreeDOS, Peter Norton's NDOS and 4NT / Take Command which add functionality to the Windows NT-style cmd.exe, MS-DOS/Windows 95 batch files (run by Command.com), OS/2's cmd.exe, and 4NT respectively are similar to the shells that they enhance and are more integrated with the Windows Script Host, which comes ...
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.
Executable files can be hand-coded in machine language, although it is far more convenient to develop software as source code in a high-level language that can be easily understood by humans. In some cases, source code might be specified in assembly language instead, which remains human-readable while being closely associated with machine code ...
Hurricanes are getting stronger, and humans are primarily to blame. A new study from Climate Central adds to a growing body of evidence that human-amplified climate change is indeed leading to ...
Mumu consists of a mix of malicious files and actual utilities. Because of the easily customised nature of this worm, many variants have been discovered, but most are generically detected under the Mumu.A name. The lone exception is Mumu.B, which is detected separately by most antivirus programs. The "standard" Mumu package consists of the ...
