How to get path and check in if statement
Hi,

I was wondering if it possible to get the path of a variable and compare that to something. Basically I want to write a script that checks if my $JAVA_HOME is correct and if not then it sets it. So far I have...

Code:
if [[$JAVA_HOME != '/pathhere']]
then
export JAVA_HOME='/pathhere'
echo JAVA_HOME='/pathhere'
fi

Problem is that the script can't seem to understand that I want to compare the path $JAVA_HOME and not what's in there. Anyone know how to just extract the path from that already set variable? 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.
