Running a Java Programm with a (korn)shell-script
hey everyone,

For my studies i had to write a javaprogram which reads 2 integers from the keyboard and then using the basic operations(addition, division etc) with them. so far no problem. but now i gotta make a shell-script which:

runs the program(compiled with javac)
#!bin/ksh
java Aufgabe1 > test1.log

so far so good. of course it works if i manually type the numbers. result and everything in the logfile are correct.
but i gotta make an inputfile(.txt) in which there are the 2 integers. so i gotta expand my script, reading the integers from the .txt file and running the program with those.

unhappily i got no clue, how to do that. anyone could help me here, plz?

regards simlmf

airport-hostmon

AIRPORT-HOSTMON(1)					      General Commands Manual						AIRPORT-HOSTMON(1)

NAME

       airport-hostmon - Host monitor for the original Apple AirPort Base Station ("Graphite"), the Lucent RG-1000 base station and the Apple Air-
       Port Extreme Base Station

SYNOPSIS

       airport-hostmon

DESCRIPTION

       airport-hostmon allows you to monitor the wireless hosts associated to your base station.

OPTIONS

       airport-hostmon accepts no command-line options. airport-hostmon is a wrapper  script  around  the  HostMonitor.jar  jar  file  located	in
       /usr/share/java/airport-utils.

       You  can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG environ-
       ment variable to 1 to get the debug output from the wrapper script.

ENVIRONMENT VARIABLES

       DEBUG  Set this variable to 1 to get the debug output from the wrapper script.

       JAVACMD
	      The full path to the Java Virtual Machine to use.  By  default,  the  wrapper  uses  JAVACMD;  if  it  is  not  set,  it	looks  for
	      JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can
	      be configured using the Debian alternatives system (see update-alternatives(8)).

       JAVA_HOME
	      The full path where your JDK/JRE is installed.

       JAVA_BINDIR
	      The full path to the directory where the java executable is located.

       JAVA_ARGS
	      Extra command-line arguments to be passed to the Java Virtual Machine.
