'''dbx''' is the IRIX debugger used for [[IRIS Development Option]] and [[MIPSPro]] based binaries. It is the primary system debugger, available in the "ProDev Workshop" CDs.

== Cheat Sheet ==
For those unfamiliar, this section explains how to load and use it.

=== Getting Started ===
% dbx [program] – Launch dbx with a program.

% dbx [program] program.core – Load a core dump.

% dbx -I [path] – Add search path for source files.

=== Running Programs ===
run [args] – Run the program with optional arguments.

rerun – Restart program with the same arguments.

kill – Stop the current program.

quit – Exit dbx.

=== Breakpoints ===
stop in function – Break at a function.

stop at file:line – Break at a line.

delete n – Delete breakpoint number n.

status – List breakpoints.

==== GDB Equivalents ====
dbx: stop in func → gdb: break func

dbx: stop at file:line → gdb: break file:line

dbx: status → gdb: info breakpoints

=== Stepping & Execution Control ===
step – Step into.

next – Step over.

cont – Continue.

where – Show call stack.

up / down – Move in the call stack.

==== GDB Equivalents ====
dbx: step → gdb: step

dbx: next → gdb: next

dbx: cont → gdb: continue

dbx: where → gdb: backtrace

=== Examining Variables ===
print var – Show variable.

whatis var – Show type.

dump var – Expand structure contents.

display var – Auto‑print each step.

undisplay var – Remove display.

==== GDB Equivalents ====
dbx: print → gdb: print

dbx: whatis → gdb: ptype

dbx: dump → gdb: print *var or info locals

=== Modifying State ===
assign var = value – Set variable.

call function(args) – Call a function in the debugged program.

==== GDB Equivalents ====
dbx: assign → gdb: set var var=value

dbx: call → gdb: call

=== Source Navigation ===
list – Show code around the current location.

list file:line – Show code for a specific place.

=== Signals ===
ignore signal – Ignore a signal.

handle signal – Let program handle signal.

catchsignal signal – Break when a signal occurs.

==== GDB Equivalents ====
dbx: ignore → gdb: handle SIGX ignore

dbx: catchsignal → gdb: catch signal

=== Core Files ===
debug [program] program.core – Load executable + core.

where – Inspect stack.

dump var – Inspect state.

=== Useful Misc Commands ===
help – Show help.

help topic – Help on a specific topic.

sh command – Run a shell command.
