gij - GNU interpreter for Java bytecode SYNOPSIS
gij [OPTION] ... JARFILE [ARGS...] gij [-jar] [OPTION] ... CLASS [ARGS...] [-cp path] [-classpath path] [-Dname[=value]...] [-ms=number] [-mx=number] [-Xargument] [-verbose] [-verbose:class] [--showversion] [--version] [--help][-?] DESCRIPTION
"gij" is a Java bytecode interpreter included with "libgcj". "gij" is not available on every platform; porting it requires a small amount of assembly programming which has not been done for all the targets supported by gcj. The primary argument to "gij" is the name of a class or, with "-jar", a jar file. Options before this argument are interpreted by "gij"; remaining options are passed to the interpreted program. If a class name is specified and this class does not have a "main" method with the appropriate signature (a "static void" method with a "String[]" as its sole argument), then "gij" will print an error and exit. If a jar file is specified then "gij" will use information in it to determine which class' "main" method will be invoked. "gij" will invoke the "main" method with all the remaining command-line options. Note that "gij" is not limited to interpreting code. Because "libgcj" includes a class loader which can dynamically load shared objects, it is possible to give "gij" the name of a class which has been compiled and put into a shared library on the class path. OPTIONS
-cp path -classpath path Set the initial class path. The class path is used for finding class and resource files. If specified, this option overrides the "CLASSPATH" environment variable. Note that this option is ignored if "-jar" is used. -Dname[=value] This defines a system property named name with value value. If value is not specified then it defaults to the empty string. These system properties are initialized at the program's startup and can be retrieved at runtime using the "java.lang.System.getProperty" method. -ms=number Equivalent to "-Xms". -mx=number Equivalent to "-Xmx". -noverify Do not verify compliance of bytecode with the VM specification. In addition, this option disables type verification which is otherwise performed on BC-ABI compiled code. -X -Xargument Supplying "-X" by itself will cause "gij" to list all the supported "-X" options. Currently these options are supported: -Xmssize Set the initial heap size. -Xmxsize Set the maximum heap size. -Xsssize Set the thread stack size. Unrecognized "-X" options are ignored, for compatibility with other runtimes. -jar This indicates that the name passed to "gij" should be interpreted as the name of a jar file, not a class. --help -? Print help, then exit. --showversion Print version number and continue. --fullversion Print detailed version information, then exit. --version Print version number, then exit. -verbose -verbose:class Each time a class is initialized, print a short message on standard error. "gij" also recognizes and ignores the following options, for compatibility with existing application launch scripts: "-client", "-server", "-hotspot", "-jrockit", "-agentlib", "-agentpath", "-debug", "-d32", "-d64", "-javaagent", "-noclassgc", "-verify", and "-verifyremote".
