They can automate everyday tasks, shorten the required time to do something, and translate a complex process into something anyone could operate. Add your commands, starting with echo [off], followed by—each in a new line—title [title of your batch script], echo [first line], and pause.
By Vic Laurie Batch files or scripts are small easy-to-write text files that carry out a series of commands.
They can be simple enough that even the average home computer user can take advantage of them. Systems administrators and power users are well aware of the utility of batch files but the average PC user is generally unacquainted with them or is intimidated by the notion of writing or even running a script.
This is unfortunate since it means that many are foregoing the use of a powerful tool for carrying out routine or repetitive tasks. Although batch files can be quite sophisticated and used for complicated network and system administration, they can also be of the utmost simplicity and very brief.
In this article, I will introduce the batch file and discuss some uncomplicated examples that make basic tasks easier. What is a batch file?
These are simple text files containing some lines with commands that get executed in sequence, one after the other. Files of this type are recognized and executed through an interface sometimes called a shell provided by a system file called the command interpreter.
Constructing a batch file consists of nothing more than opening any text editor like the accessory Notepad, entering some lines containing commands, and saving the file with an extension BAT or CMD.
In Windows XP, Vista, and 7 there is little practical difference between the two extensions. Don't use Wordpad or Word unless you are very careful to save all files in pure text format. The commands themselves are often quite simple and there is no need to learn a programming language.
Those who wish can explore the intricacies that are available with branching and looping but here I will confine the discussion to some straightforward application to everyday tasks.
The focus will be on saving time and effort for some routine stuff like system housekeeping and simple file management. Running a batch file is a simple matter of clicking on it. Batch files can also be run in a command prompt or the Start-Run line. In that case, the full path name must be used unless the file's path is in the path environment.
Constructing a batch file In the following discussion it is assumed that the Introductory page and the page on Commands have been read. The first line in a batch file often consists of this command echo offBy default, a batch file will display its commands as it runs.
The purpose of this first command is to turn off this display.
The command "echo off" turns off the display for the whole script, except for the "echo off" command itself. The "at" sign " " in front makes the command apply to itself as well. This nuance isn't really all that important in the context here but I mention it because it is often seen in scripts.
The scripts we will discuss are very brief and omitting this line won't make any great difference.
However, as a matter of good practice, we will enter it in our scripts. Our first batch file example is going to list all the files in a folder and put the list in a new text file.
We will use the directory command "dir" that is discussed on another page. Open Notepad and enter the line " echo off" without quotes. Next enter another line dir "C: This will give us the two-line file echo offdir "C: Be sure that Notepad is saving as "All files" and not as a text file.
See the figure below. Three important points are illustrated in the example script. Note that complete paths are used for files including the drive letter. Also note the quotes around "C: Paths must be quoted whenever a file or folder name has a space in it.
All that has to be done to use the file is to double-click it. A more general version with arguments The file that we have been discussing is limited to listing one particular folder and putting the list in one particular file.
However, it is easy to make the file able to list whatever folder we want and to put the list wherever we want. Batch files can use arguments or data that is input from the user. This type of situation cannot be clicked directly but should be run in a command prompt. Now you have a little program that will list the contents of a folder whenever you want.I need to move files from one directory to another in windows, and I need to write this in a batch script.
