How to write a batch file to copy files from one drive to another

Introduction[ edit ] This book addresses bit Windows commands applicable to modern versions of Windows based on the Windows NT environment.

You can find out which version of cmd. This book first describes using the Windows NT command interpreter, how it receives, parses, and processes commands from users. Then it describes various commands available. To obtain an extensive list of Windows commands and their short summaries, open the command prompt on any Windows computer, and type help.

The subject of this book is also known as "batch programming", even though "batch" refers not only to batch files for MS DOS and Windows command interpreter. Other subject terms include "batch file programming", "batch file scripting", "Windows batch command", "Windows batch file", "Windows command line", "Windows command prompt", and "Windows shell scripting".

Using the Windows command interpreter[ edit ] How a command line is interpreted[ edit ] The parsing of a command line into a sequence of commands is complex, and varies subtly from command interpreter to command interpreter.

There are, however, four main components: Variable substitution A command line is scanned for variable specifications, and any found are replaced with the contents of those variables. Quoting Special characters can be quoted, to remove their special meanings. Syntax Command lines are developed into a sequence of commands according to a syntax.

Redirection Redirection specifications are applied, and removed from the command line, before an individual command in a sequence is executed. Variable substitution[ edit ] Command lines can contain variable specifications. Variable specifications are replaced with values as follows: See also Command-line arguments.

Special names[ edit ] Some variable names are not visible using SET command. To find out about them, type "help set". Special variable names and what they expand to: You can surround a string containing a special character by quotation marks.

A newline can be escaped using caret as well. When you surround the string using quotation marks, they become part of the argument passed to the command invoked.

By contrast, when you use caret as an escape character, the caret does not become part of the argument passed. Enclosing the percent sign in quotation marks or preceding it with caret does not work. No quotes are echoed. Caret needs escaping as well or else it is interpreted as escaping a space.

When after a pipe, a caret used for escaping needs to be tripled to work; the fourth caret is the one being escaped.

The caret at the end of the line escapes the newlines, leading to the three lines being treated as if they were a single line. The space before the first caret is necessary or else 1 gets joined with the following echo to yield 1echo. Using quotes, as in attrib "File 1.

If run from a batch, the percent sign is ignored.A coworker asked me for a script. Here’s the request: would want to copy all files on this list [an attached text document] to another location (doesn’t really matter where for now).

Processing Lists of Data. A nagging problem in batch programming is how to take a list of items in a file and do anything useful with it.

One solution is to use Ed Schwartz' @.COM program or a similar external utility, but there is a way to do it entirely with batch if certain precautions are taken.

Explanation After the header information, the batch file clears the screen and displays a directory listing of the `B' drive so you see what, if any, files are on the drive.

In computing, a cache (/ k æ ʃ / kash, or / ˈ k eɪ ʃ / kaysh in AuE) is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere.A cache hit occurs when the requested data can be found in a cache, while a cache miss occurs when it.

Batch Files What are batch files? Batch files are not programs, pre se, they are lists of command line instructions that are batched together in one file.

For the most part, you could manually type in the lines of a batch file and get the same results, but batch files make this work easy.
