Command Prompt assumes both the role of interpreter and runtime environment. Put simply, a batch file is a computer program or script containing data or tasks that are processed sequentially by Command Prompt.
Back then, data sets were usually stored on punched cards that were processed one card at a time in batches. Batch files allow you to use and run ordinary CMD commands with cmd. You can also use comments , labels , variables , conditions , and queries when writing a batch file.
To convert text files to batch files, you have to use the. In , Microsoft released PowerShell , another framework that allows you to program and execute batch files. It was made open-source and cross-platform in and uses the MIT license.
PowerShell provides an alternative command line interpreter and its own scripting language called PowerShell Scripting Language. Creating your own batch files is useful for automating the execution of recurring command sequences. These sequences might include login processes or what is known as TSR programs T erminate and S tay R esident that you want to run continuously as background processes. As mentioned earlier, text documents are a good starting point for batch scripts. To write your own batch file, all you need is an ordinary text editor.
But you do need to know common system commands and understand how they work in batch files. Here are the most important commands to learn:. For a complete list of the most important commands, see our comprehensive article on batch commands.
An easy introduction to the art of creating batch files is to write a simple script that creates multiple directories on a selected disk on your computer. To save these batch instructions or the script, click File and choose Save As Specify the save location and enter a name for the script with the extension. After you create and save the batch file, you have two options to run it: Either run the script in the familiar Windows Explorer environment or open Command Prompt and run it using a command-line command.
The first option is simpler and easier for beginners because all you have to do is go to the directory where the batch file is located and double-click to run it. If a batch script contains commands that require administrator privileges to execute, you have to run the script as an administrator.
You can customize a batch script at any time , for example if you want to add or remove commands or modify directories. To do this, simply go to the folder containing the command line script and right-click it. Then choose Edit :. With the above step-by-step guide, you can create a wide variety of batch files with an unlimited number of different commands.
However, scripts that you can use more frequently are definitely more useful in the long run. The following example shows how useful batch files can be for creating regular back-ups of any directory:. The three parameters at the end have the following effect:.
The above backup program allows you to copy the source files from the source folder to the destination folder. You can also create a batch file that distributes source data to multiple destination folders , in which case you can use the file type as a selection criterion.
To do this, you need a for loop , which allows a command to run repeatedly with a variable argument:. The PostgreSQL database management system, also known to many as Postgres, has many decades of development behind it. It originally started as a project at Berkeley University in California. Today, the open source database continues to defy solutions from commercial competitors, since the development team is constantly working on its functionality and performance.

In Windows, if the script is executed from an already running command prompt window, the window remains open at the prompt as in MS-DOS; otherwise, the window closes on termination. Variable expansions are substituted textually into the command, and thus variables which contain nothing simply disappear from the syntax, and variables which contain spaces turn into multiple tokens.
This can lead to syntax errors or bugs. The text that is being compared to the variable must also be enclosed in quotes, because the quotes are not special delimiting syntax; these characters represent themselves. The delayed!
In this case, null or multi-word variables do not fail syntactically because the value is expanded after the IF command is parsed:. Another difference in Windows or higher is that an empty variable undefined is not substituted.
As described in previous examples, previous batch interpreter behaviour would have resulted in an empty string. Batch interpreters prior to Windows would have displayed result MyVar is not defined. As a result, each Windows application can implement its own parser to split the entire command line into arguments. Many applications and command-line tools have evolved their own syntax for doing that, and so there is no single convention for quoting or escaping metacharacters on Windows command lines.
Where a string contains quotation marks, and is to be inserted into another line of text that must also be enclosed in quotation marks, particular attention to the quoting mechanism is required:. On Windows and later, the solution is to replace each occurrence of a quote character within a value by a series of three quote characters:. Some characters, such as pipe characters, have special meaning to the command line. However, escaping does not work as expected when inserting the escaped character into an environment variable.
The variable ends up containing a live pipe command when merely echoed. It is necessary to escape both the caret itself and the escaped character for the character display as text in the variable:. No solution was available from Microsoft, but a number of small utility programs, could be installed from other sources. Most such programs are bit.
COM files, so are incompatible with bit Windows. Normally, all printed text automatically has the control characters for carriage return CR and line feed LF appended to the end of each line. It is not possible to have a command prompt that uses a UNC path as the current working directory; e. The command prompt requires the use of drive letters to assign a working directory, which makes running complex batch files stored on a server UNC share more difficult. So to run a batch file on a UNC share, assign a temporary drive letter to the UNC share, and use the UNC share as the working directory of the batch file, a Windows shortcut can be constructed that looks like this:.
When an administrator is logged on and UAC is enabled, and they try to run a batch file as administrator from a network drive letter, using the right-click file context menu, the operation will unexpectedly fail. This is because the elevated UAC privileged account context does not have network drive letter assignments, and it is not possible to assign drive letters for the elevated context via the Explorer shell or logon scripts.
UNC default paths are turned off by default as they used to crash older programs. Batch files use an OEM character set, as defined by the computer, e. Code page File names with characters outside this set do not work in batch files. As with any other programming language, batch files can be used maliciously. Simple trojans and fork bombs are easily created, and batch files can do a form of DNS poisoning by modifying the hosts file.
Batch viruses are possible, and can also spread themselves via USB flash drives by using Windows' Autorun capability. The following command in a batch file will delete all the data in the current directory folder - without first asking for confirmation:.
These three commands are a simple fork bomb that will continually replicate itself to deplete available system resources, slowing down or crashing the system:. The cmd. EXE, which interprets. BAT files, was supported in all and bit versions up to at least Windows There are other, later and more powerful, scripting languages available for Windows. However, these require the scripting language interpreter to be installed before they can be used:. Script files run if the filename without extension is entered.
There are rules of precedence governing interpretation of, say, DoThis if DoThis. From Wikipedia, the free encyclopedia. Batch file Filename extensions. All rights reserved. COM at the bit Windows 7 command prompt. If a network path is specified, PUSHD creates a temporary drive letter that points to that specified network resource and then change the current drive and directory, using the newly defined drive letter.
This is typically added to the start of most batch files. There are other directions you could go with a batch file like this. For example, you might want to have your batch script run the above commands and then dump the output to a text file you can view later. The Command Prompt window will automatically close once the batch file is done running.
However, many batch files are designed to be run non-interactively. For example, you could have a batch file that deletes multiple files or directories whenever you double-click it. However, batch files can actually be significantly more complex than this. This is more like writing an actual small program than a quick and dirty script.
