Debugger commands:

  apropos           -- List debugger commands related to a word or subject.

  breakpoint        -- Commands for operating on breakpoints (see 'help b' for

                       shorthand.)

  command           -- Commands for managing custom LLDB commands.

  disassemble       -- Disassemble specified instructions in the current

                       target.  Defaults to the current function for the

                       current thread and stack frame.

  expression        -- Evaluate an expression on the current thread.  Displays

                       any returned value with LLDB's default formatting.

  frame             -- Commands for selecting and examing the current thread's

                       stack frames.

  gdb-remote        -- Connect to a process via remote GDB server.

                       If no host is specifed, localhost is assumed.

                       gdb-remote is an abbreviation for 'process connect

                       --plugin gdb-remote connect://<hostname>:<port>'

  gui               -- Switch into the curses based GUI mode.

  help              -- Show a list of all debugger commands, or give details

                       about a specific command.

  kdp-remote        -- Connect to a process via remote KDP server.

                       If no UDP port is specified, port 41139 is

                       assumed.

                       kdp-remote is an abbreviation for 'process connect

                       --plugin kdp-remote udp://<hostname>:<port>'

  language          -- Commands specific to a source language.

  log               -- Commands controlling LLDB internal logging.

  memory            -- Commands for operating on memory in the current target

                       process.

  platform          -- Commands to manage and create platforms.

  plugin            -- Commands for managing LLDB plugins.

  process           -- Commands for interacting with processes on the current

                       platform.

  quit              -- Quit the LLDB debugger.

  register          -- Commands to access registers for the current thread and

                       stack frame.

  reproducer        -- Commands for manipulating reproducers. Reproducers make

                       it possible to capture full debug sessions with all its

                       dependencies. The resulting reproducer is used to replay

                       the debug session while debugging the debugger.

                       Because reproducers need the whole the debug session

                       from beginning to end, you need to launch the debugger

                       in capture or replay mode, commonly though the command

                       line driver.

                       Reproducers are unrelated record-replay debugging, as

                       you cannot interact with the debugger during replay.

  script            -- Invoke the script interpreter with provided code and

                       display any results.  Start the interactive interpreter

                       if no code is supplied.

  session           -- Commands controlling LLDB session.

  settings          -- Commands for managing LLDB settings.

  source            -- Commands for examining source code described by debug

                       information for the current target process.

  statistics        -- Print statistics about a debugging session

  swift-healthcheck -- Provides logging related to the Swift expression

                       evaluator, including Swift compiler diagnostics. This

                       makes it easier to identify project misconfigurations

                       that result in module import failures in the debugger.

                       The command is meant to be run after a expression

                       evaluator failure has occurred.

  target            -- Commands for operating on debugger targets.

  thread            -- Commands for operating on one or more threads in the

                       current process.

  trace             -- Commands for loading and using processor trace

                       information.

  type              -- Commands for operating on the type system.

  version           -- Show the LLDB debugger version.

  watchpoint        -- Commands for operating on watchpoints.
