![]() ![]() Now, just because they are called command line arguments does not mean they can only be used from a console. You type in the name of the program, followed by its arguments that tell the program how it should operate. This same behavior works in Terminal on macOS and Linux as well as any other console environment. Therefore a valid use of the move program would be move test.txt c:\, which would move the test.txt file to the root of the C:\ drive as shown below. Let's use the move program as an example.This command requires two command line arguments the file to move and where you wish to move it. In a graphical user interface, when you want to move a file from one folder to another, you just drag it. On the other hand if you want to move a file from a console command, you need to specify the file and location using command line arguments, which are typed after the program name.įor example, in a Windows Command Prompt, to execute a program you must type its name and press Enter on the keyboard. These programs typically take arguments in order to work properly and these arguments are called command line arguments. Program's arguments are named command line arguments because they are typically used when you type them within a console, command prompt, or terminal. Instead you must add a space so it looks like notepad.exe /s. ![]() For example, notepad.exe/s is not a valid argument because it does not contain a space. It is important to note that you must add a space between the program you want to run and the command line argument. So for example, if we launched Notepad using the command C:\Windows\System32\notepad.exe /s, then /s would be the command line argument we used. Note, in the shortcut Target field below, %windir% means the folder Windows is installed into, which is usually C:\Windows on most PCs.Ī command line argument is simply anything we enter after the executable name, which in the above example is notepad.exe. All this does is start the Notepad.exe program as shown by the Target field in the shortcut properties below. To launch it, you would simply type notepad into the search field and press enter or click on its icon. ![]() For example, the C:\Windows\system32\notepad.exe program is the Windows Notepad. In Windows, when you start a program by clicking on it's icon, or shortcut, it simply runs an executable and the program runs with whatever default settings are programmed into it. In order to understand what a command line argument is, we should show an example of how a program is normally launched. ![]() Depending on the program, these arguments can be used to add more features that includes specifying a file that output should be logged to, specifying a default document to launch, or to enable features that may be a bit buggy for normal use. What are Command Line Arguments and why would you use them?Ĭommand line arguments are extra commands you can use when launching a program so that the program's functionality will change.
