DBX Notes

acts as a shell. unrecognized commands are pushed back up to the shell above if unrecognized on Sun machines or prefixed by sh on IBM machines.
debug to debug a core dump.
where to print out the current location in a stack.
up to go up a stack trace level.
down to go down a stack trace level.
print <> to print out the contents of a variable. Can dereference pointers or get raw addresses pointers point to, but this seems to be a little flawed when dealing with core dumps.
stop at adds a breakpoint at the specified line in the currently loaded file.
stop in >symbol name< adds a breakpoint at the beginning of the specified symbol/function.
stop at "filename.c":123 adds a breakpoint at the specified line of the specified file.
run [args] allows the current executable to be started from the debugger. Arguments can be specified.
status lists current breakpoints (with indexing numbers).
delete deletes a specific weekend.
cont to continue from a breakpoint.
next[i] to move on to the next line of code (or instruction).
step[i] to step into the code (or instruction).
examine
/>count< to display (in a fairly raw format) count bytes of memory starting at address.
list [-10] to display the source around stack.
