echo-test-single-instance.sh script

The echo-test-single-instance.sh script helps you understand the script output format. The script generates a random number between 0 to 100. This number is used as the KM value. The random number value is displayed in text in the annotation. 

This script is available at $PATROL_HOME\..\TRO\Conf\Scripts\Samples directory. The script content is as follows:

#!/bin/sh -f
#=======================================================================================================
# This sample is provided as a 'hello world' kind of script.
# One which help the KM user understand the required format of script output.
# Every time the script is called, it generates a random number in the range of 0..100
# That number is used as value for the KM.
# Annotation is then added printing text converting the digits of that random number into words.
#
# In this case the script is printing in format what would allow a single value with multi-line annotation
# the format is:
# <numeric value>
# <some annotating text>
