xrun

xrun is a command-line utility that facilitates the execution of external programs. It is primarily used within the X Window System environment on Unix-like operating systems to launch applications. The utility takes the name of an executable program as an argument and, if successful, starts that program. It can also accept additional arguments that are passed directly to the executed program. xrun is often found in scripting contexts where the automation of launching graphical applications is necessary. It's a simple yet fundamental tool for interacting with the X server and managing application processes. Its existence simplifies the process of invoking programs that are designed to run within a graphical session, making it a useful component for system administrators and developers alike. The command itself is straightforward, requiring only the program name and any subsequent parameters.
