  - command
```
Optional<String> command()
```
    Returns the executable pathname of the process.
    
    Returns:
    
    an Optional<String> of the executable pathname of the process
  - commandLine
```
Optional<String> commandLine()
```
    Returns the command line of the process.
    If command() and arguments() return non-empty optionals, this is simply a convenience method which concatenates the values of the two functions separated by spaces. Otherwise it will return a best-effort, platform dependent representation of the command line.
