I also fixed a syntax error in the usage echo to escape the greater-than and less-than signs. EXE" and to get. I think it is actually taking the parentheses to be part of the strings and they are being compared.
This is the same as the other answers, but uses only one label and puts the usage first, which additionally makes it serve as a kind of documentation commend of the script which is also usually placed at the top:.
Minin 73 1 2 Following are common addresses and ports: CrashPlan for Small Business: Contact your Code42 administrator for the address.

Below are the relational operators available. Logical operators are used to evaluate Boolean expressions. Following are the logical operators available. The only logical operator available for conditions is the NOT operator. Batch Script language also provides assignment operators. Following are the assignment operators available. The date and time in DOS Scripting have the following two basic commands for retrieving the date and time of the system.
Following are some implementations which can be used to get the date and time in different formats. Each of these three standard files, otherwise known as the standard streams, are referenced using the numbers 0, 1, and 2.
Stdin is file 0, stdout is file 1, and stderr is file 2. One common practice in batch files is sending the output of a program to a log file. The following example shows how this can be done. In the above example, the stdout of the command Dir C: If you append the number 2 to the redirection filter, then it would redirect the stderr to the file lists. Following is an example. The pseudo file NUL is used to discard any output from a program.
To work with the Stdin, you have to use a workaround to achieve this. The following example shows how you can redirect the output to a file called lists.
After you execute the below command, the command prompt will take all the input entered by user till it gets an EOF character. Later, it sends all the input to the file lists. By default when a command line execution is completed it should either return zero when execution succeeds or non-zero when execution fails. When a batch script returns a non-zero value after the execution fails, the non-zero value will indicate what is the error number.
We will then use the error number to determine what the error is about and resolve it accordingly. In the batch file, it is always a good practice to use environment variables instead of constant values, since the same variable get expanded to different values on different computers.
Similarly, if we see that the variable userprofile is not defined then we should set the errorlevel code to 9. Now, if the Find. In the following batch file, after calling the Find. If the variable userprofile does not exist, then nothing will be displayed in the console output. In the decision making chapter, we have seen statements which have been executed one after the other in a sequential manner. They are then classified into flow of control statements. There is no direct while statement available in Batch Script but we can do an implementation of this loop very easily by using the if statement and labels.
The "FOR" construct offers looping capabilities for batch files. Following is the general form of the statement.
The above command will produce the following output if the batch file passes the command line arguments of 1,2 and 3 as Test. The break statement is used to alter the flow of control inside loops within any programming language. The break statement is normally used in looping constructs and is used to cause immediate termination of the innermost enclosing loop.
A function is a set of statements organized together to perform a specific task. In batch scripts, a similar approach is adopted to group logical statements together to form a function. In Batch Script, a function is defined by using the label statement. When a function is newly defined, it may take one or several values as input 'parameters' to the function, process the functions in the main body, and pass back the values to the functions as output 'return types'.
Every function has a function name, which describes the task that the function performs. To use a function, you "call" that function with its name and pass its input values known as arguments that matches the types of the function's parameters. Local variables in functions can be used to avoid name conflicts and keep variable changes local to the function. The ability to completely encapsulate the body of a function by keeping variable changes local to the function and invisible to the caller.
This filter can be used to redirect any output to a file. This filter can be used to append any output to a file. Reading of files in a batch script is done via using the FOR loop command to go through each line which is defined in the file that needs to be read.
When a batch file is run, it gives you the option to pass in command line parameters which can then be read within the program for further processing. In Batch Script, it is possible to perform the normal folder based operations that would be expected in any programming language. The listing of folder contents can be done with the dir command. This command allows you to see the available files and directories in the current directory.
If the module name is not specified all loaded modules are displayed. Specifies that the "Column Header" should not show in the output. The above command will get the list of all the processes running on your local system. Following is a snapshot of the output which is rendered when the above command is run as it is. As you can see from the following output, not only do you get the various processes running on your system, you also get the memory usage of each process.
The above command will only fetch those processes whose memory is greater than 40MB. Following is a sample output that can be rendered. Applies a filter to select a set of tasks.
Specifies the image name of the process to be terminated. DOS scripting also has the availability to start a new process altogether.
The above command will run the batch script test. Aliases means creating shortcuts or keywords for existing commands. Create a new file called keys. The below commands creates two aliases, one if for the cd command, which automatically goes to the directory called test. And the other is for the dir command. After which we are setting it to NULL. Because we have set the value of d to NULL, the macro d will deleted.
Windows now has an improved library which can be used in Batch Script for working with devices attached to the system. This is known as the device console — DevCon. Windows driver developers and testers can use DevCon to verify that a driver is installed and configured correctly, including the proper INF files, driver stack, driver files, and driver package. You can also use the DevCon commands enable, disable, install, start, stop, and continue in scripts to test the driver.
DevCon is a command-line tool that performs device management functions on local computers and remote computers. These identifiers are described in detail in device identification strings. Search for devices DevCon can search for installed and uninstalled devices on a local or remote computer by hardware ID, device instance ID, or device setup class. The backslashes are required.
Reboots the system after completing an operation only if a reboot is required to make a change effective. The following command uses the DevCon DriverFiles operation to list the file names of drivers that devices on the system use. The following command uses the DevCon status operation to find the status of all devices on the local computer. It then saves the status in the status. The following command enables all printer devices on the computer by specifying the Printer setup class in a DevCon Enable command.
The following command uses the DevCon Install operation to install a keyboard device on the local computer. The command includes the full path to the INF file for the device keyboard. The Registry is one of the key elements on a windows system. It contains a lot of information on various aspects of the operating system.
Almost all applications installed on a windows system interact with the registry in some form or the other. The Registry contains two basic elements: Registry keys are container objects similar to folders. Registry values are non-container objects similar to files. Keys may contain values or further keys. Keys are referenced with a syntax similar to Windows' path names, using backslashes to indicate levels of hierarchy.
