It expands to the command-line parameters passed to the script. However, it's wrong; it should be in double quotes, like "$@"

Code:

vnix$ cat >script
echo args: "$@"
for f in "$@"; do echo "arg: $f"; done
^D
vnix$ sh ./script foo bar baz
args: foo bar baz
arg: foo
arg: bar
arg: baz

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.
