-lite

-rich

Perform a detailed stack back-trace that includes, where possible, inlined function calls, parameter names and values, and debug-names. Equivalent to -print inline,params,debug-names.

-print print-option,...

Specify the level of detail to include in a stack back-trace. print-option can be any of:
debug-names: use debug information, such as DWARF, to determine the name of functions
paths: include the full path to source files and libraries
inline: include in-line function in back-trace
locals: to include local variables from each frame
params: include the function parameters
To negate a print-option prefix it with "-".

Standard Frysk Options

-exe

The full path of the executable to read.

-noexe

Do not attempt to read the corresponding executable when loading a core file.

-sysroot directory

The system root directory under which all executables, libraries, and source are located.

-debug class=level...

Set internal debug-tracing of the specified Java class to level (level can be NONE, INFO, WARNING, FINE, and FINEST). If the level is absent, FINE is assumed; if the class is absent, the global level is set.
