Executing Shell Scripts
Hi, I'm pretty new to Unix and I just have a question concerning making a script executable without putting the "sh" command before it. In case it makes the difference I am on an Apple computer using the Terminal. Anyway here is the little test code I wrote followed by the commands I took to try to make it executable on its own.
Script
#! /bin/sh
# comments
echo "blah"
heh that's it, it works when I do enter sh Script
now then the code I tried to use to execute it
chmod u+x Script
pwd ; echo $PATH
and though no errors came up, it didn't work. So any insight would be really appreciated. Thanks.

airport2-portinspector
AIRPORT2-PORTINSPECTOR(1) General Commands Manual AIRPORT2-PORTINSPECTOR(1)
NAME
airport2-portinspector - Port maps inspector for the Apple AirPort Extreme Base Station ("Snow")
SYNOPSIS
airport2-portinspector
DESCRIPTION
airport2-portinspector allows you to inspect the port maps used by the hosts associated with your base station.
OPTIONS
airport2-portinspector accepts no command-line options. airport2-portinspector is a wrapper script around the PortInspector.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.
