To make this even more useful, you could then output to another le:

Finally, if you don t want to use les, you can pipe output from one command to another using the | character and send the output of one command to another, for example:
Generating EAN / UCC - 13 In .NET
Using Barcode creation for ASP.NET Control to generate, create EAN13 image in ASP.NET applications.
Command 1 | command 2

22 THE COMMAND PROMPT AND POWERSHELL
Encode Barcode In .NET
Using Barcode generation for .NET Control to generate, create bar code image in VS .NET applications.
This code sends the output from command 1 as the input to command 2 For example, if you want to perform a directory listing of a directory and return only the les that have a certain text string in their name, use the following command:

Code 39 Extended Creation In Visual Studio .NET
Using Barcode maker for .NET framework Control to generate, create Code 39 image in .NET applications.
One common use of the pipe capability is adding | more to the end of a command, which sends the output to the more command The more command displays a screen of output and then waits for the Enter key to be pressed to display an additional line of text This is useful for commands that don t have the capability to slowly display information One nal tip is | clip, which takes the output and sends it to the Clipboard

Multiple Commands
Drawing Code 39 Full ASCII In Visual C#
Using Barcode generator for Visual Studio .NET Control to generate, create Code 3 of 9 image in .NET framework applications.
It is possible to chain commands together with varying levels of complexity The simplest method is to use a single ampersand symbol (&), which simply runs multiple commands consecutively:
GTIN - 12 Creator In Java
Using Barcode drawer for Java Control to generate, create UPC-A Supplement 5 image in Java applications.
command1 & command2
Barcode Scanner In Java
Using Barcode reader for Java Control to read, scan read, scan image in Java applications.

Barcode Generation In .NET Framework
Using Barcode creation for ASP.NET Control to generate, create barcode image in ASP.NET applications.
The Command Prompt and PowerShell
Generating Bar Code In VB.NET
Using Barcode generation for VS .NET Control to generate, create bar code image in VS .NET applications.
Command1 runs rst and then command2 runs, regardless of the success of command1 For example, running netstat & echo %time% would list the active connections and then write out the current time You are not limited to two commands; you can keep adding additional commands, with each command separated by an ampersand If you require a second command to run only if the rst command succeeds, use two ampersand characters (&&) For example, if you run clip with an invalid parameter, the second command will not run:
UCC-128 Printer In Java
Using Barcode generation for Java Control to generate, create GTIN - 128 image in Java applications.
C:\>clip /error && echo worked ERROR: Invalid argument/option - /error Type CLIP / for usage
Printing Code 128B In Java
Using Barcode generation for Java Control to generate, create Code128 image in Java applications.
A working command shows the worked output text:

Using Barcode scanner for .NET framework Control to read, scan read, scan image in VS .NET applications.
C:\>set test=value && echo worked worked
Drawing Code 128A In .NET Framework
Using Barcode creation for ASP.NET Control to generate, create Code-128 image in ASP.NET applications.
Taking the rst example, you can use a double || to run a command only if the previous command fails:

Using Barcode maker for .NET Control to generate, create barcode image in .NET framework applications.
C:\>clip /error || echo not working ERROR: Invalid argument/option - /error Type CLIP / for usage not working
Chaining is ne; however, often you require more complex sequences of commands with more granular logic beyond just success or failure, and you want to run the sequences with ease Files are used with batches of commands known as batch les, which are simply text les with a bat extension (Although a cmd extension also works and is treated the same as a batch le) The commands used before and mentioned in other chapters can all be used in a batch le In its basic form, a batch le can consist of nothing more than a series of commands; for example, a batch le could contain the following:
rem testbat echo Starting batch le hostname
CMDEXE
If testbat is executed, it runs as expected, except every line of the batch le is output to the screen, as shown here:
C:\>testbat C:\>rem testbat C:\>echo Starting batch le Starting batch le C:\>hostname savdalwks01
22 THE COMMAND PROMPT AND POWERSHELL
Output of the actual commands can be suppressed by adding @ to the start of each line or adding echo off to the top of the batch le In fact, normal convention is to add @echo off to the start of batch les to avoid the echo off displaying to screen The batch le now becomes the following:
@echo off rem testbat echo Starting batch le hostname
When executed, you get the output from the commands:
C:\>testbat Starting batch le savdalwks01
In the batch le, you have a line starting with rem, which is simply a remark in the le (also known as a comment) that is used to comment on the le content to help understand its functionality for future editing Although a batch le on its own might be useful, there will also be times that you will want to pass data to be used in its actions For example, you might want to pass a computername, username, or any other value, or perhaps a combination of values The passing of data to a batch le is made possible simply by adding the percent (%) sign to the number of the argument s position when passed to the batch le, with %0 being the actual name of the batch le Let s say you run a batch le as follows:
