OS

The OS class provides static methods to execute OS commands. It supports both synchronous and asynchronous execution, allowing users to run external programs with optional arguments.

Methods:

• exec(program: string, ...args: string[])
  Executes a program or command synchronously. This method runs the specified program with the provided arguments and waits for it to complete before returning control to the caller.

  • program: The name or path of the program/command to execute.
  • args: (Optional) A list of arguments to pass to the program/command.

• execAsync(program: string, ...args: string[]): Promise<void>
  Executes a program or command asynchronously. This method returns a Promise that resolves when the program completes its execution, allowing other tasks to continue while the program runs. Although javascript is single threaded, this method will execute external programs in a separate thread.

  • program: The name or path of the program/command to execute.
  • args: (Optional) A list of arguments to pass to the program/command.

Example 1

// Synchronously execute a program with arguments
OS.exec('notepad.exe', 'C:/example.txt');

Example 2

OS.execAsync('notepad.exe', 'C:/example.txt')
    .then(()=> console.log('Program finished running'))
    .catch(err => console.error('Error running program:', err));
