Viivi Tips

This page summarizes tips in using Viivi.

How to force Viivi to Quit

When Viivi gets out of control or when you want to force Viivi running in the kernel-mode to quit, you can use the key-combination

		[Control]+[C]

By typing once [C]-key with keeping [Control]-key pressed-down in the terminal/CMD window where Viivi was booted-up, the process for the JVM is aborted and hence Viivi is forced to quit on the most platforms.

Note that it is not a safe method but an emergency measure.
Some disadvantages may possibly occur.

Stop and Restart the Screen Scrolling

When you are using Viivi in the kernel-mode, you can miss the output contents scrolling so fast.

In such a case, you can control the screen scrolling with the key-combinations

		[Control]+[S]		Stop the screen scrolling
		[Control]+[Q]		Restart the screen scrolling

Standard I/O Files

The standard input source, the standard output destination, and the standard error-output destination, available in the most platforms, can be seen as special device files prepared in the platforms, respectively.
Typical examples are as follows:

• Special device files for the Unix-like platforms
  

  	standard-input source file				"/dev/stdin"
  	standard-output destination file		"/dev/stdout"
  	standard-error-output destination file	"/dev/stderr"
  			

• Special device files for the Windows platforms
  

  	standard-input source file				"CON"
  	standard-output source file			"CON"
  	standard-error-output source file		"ERR"
  			

	$ viivi -K -e /dev/stdout		for the Unix-like platforms (sh system) ($ is the prompt of sh)
	> viivi -K -e CON			for the Windows platforms (> is the prompt of CMD)
