* NAME
* goodbye.d - demonstrate the END probe
*
* SYNOPSIS
* sudo dtrace -s goodbye.d
*
* DESCRIPTION
* Demonstrates the use of the END probe. Function trace() is
* used to print a string.
*
* NOTES
* - The advantage of trace() is that it is simple and does not
* require a format string. If more control over the output is
* needed, printf() is a good alternative.
*
* - The script needs to be terminated with ctrl-C. In case the
* script is running in the background, get it to run in the
* foreground first by using the fg command and then use ctrl-C
* to terminate the process. Otherwise, typing in ctrl-C will do.
*/
/*
* The END probe fires once when the tracing has terminated.
*/
END

trace("Goodbye");
