On the Microsoft Windows operating system, the Run command is used to directly open an application or document whose path is known. It functions more or less like a single-line command line interface.
In the GNOME interface, the Run command is used to run applications via terminal commands. It can be accessed by pressing Alt+F2. KDE has similar functionality called KRunner. It is accessible via the same key binds.
Accessing the Run command
Starting with Windows 95, the Run command is accessible through the Start menu and also through the shortcut key ⊞ Win+R. The input field in the dialog will show roughly 40-45 characters (when using Regional Language setting of "English (United States)" and running Windows XP); although more characters than this can be entered, the characters that were first entered are not visible, as they scroll out of view to the left. If the size of the command is longer than this (e.g., if a path is included), the dialog cannot be resized.
Although the Run command is still present in Windows Vista and later, it no longer appears directly on the Start menu by default, in favor of the new search box and a shortcut to the Run command in the Accessories sub-menu.
Uses include bringing up webpages; for example, if a user were to bring up the Run command and type in
http://www.example.com/, the user's default Web Browser would open that page. This allows user to not only launch
http protocol, but also all registered URI schemes in OS and applications associated with them, like
