linux_run_script_no_jvm_template.sh

#!/bin/bash
# This script will run the program in the same location and with the same
# name as this script (without the .sh). Passing it the same set of command
# line options.

# It also parses the following environment variables
# JAVA_HOME
#    Either JAVA_HOME or JVM_SO_PATH must be set.
#    This must point to the Java home directory.
#    For instance: /usr/lib/jvm/java-6-openjdk
#    This was tested with Oracle's implementation of Java (sun-jdk or open-jdk).

# JVM_SO_PATH
#    Either JAVA_HOME or JVM_SO_PATH must be set.
#    The script will expect to find libjvm.so in 
#    $JAVA_HOME/jre/lib/amd64/client/libjvm.so or
#    $JAVA_HOME/jre/lib/amd64/server/libjvm.so
#    If libjvm.so is not in either locations, the script will fail. In which 
#    case, you should set this variable to the directory containing libjvm.so.

# USE_SYSTEM_LIBS
#    Optional. If set to 1, the system's glibc (and other system dependencies) 
#   will be used instead of the provided versions. 




# get the program name. By convention we will make it so that the 
# script's name is the same as the program name. But with a ".sh" at the end
PROG=$0
#strip the ".sh" at the end of the script name
