| 命令命令命令命令命令 | 作用 | 原文 |
|---|---|---|
| apropos | 列出与单词或主题相关的调试器命令。 | List debugger commands related to a word or subject. |
| breakpoint | 操作断点的命令(请参阅“help b”以方便速记)。 | Commands for operating on breakpoints (see 'help b' for shorthand.) |
| command | 自定义LLDB命令管理命令。 | Commands for managing custom LLDB commands. |
| disassemble | 反汇编当前目标中的指定指令。默认为当前线程和堆栈帧的当前函数。 | Disassemble specified instructions in the current target. Defaults to the current function for the current thread and stack frame. |
| expression | 计算当前线程上的表达式。使用LLDB的默认格式显示任何返回值。 | Evaluate an expression on the current thread. Displays any returned value with LLDB's default formatting. |
| frame | 用于选择和检查当前线程的堆栈帧的命令。 | Commands for selecting and examing the current thread's stack frames. |
| gdb-remote | 通过远程GDB服务器连接到一个进程。如果没有指定主机，则假定为localhost。 | Connect to a process via remote GDB server. If no host is specifed, localhost is assumed. |
| gui | 切换到基于GUI的诅咒模式。 | Switch into the curses based GUI mode. |
| help | 显示所有调试器命令的列表，或给出有关特定命令的详细信息。 | Show a list of all debugger commands, or give details about a specific command. |
| kdp-remote | 通过远程KDP服务器连接到一个进程。如果没有指定UDP端口，则假定端口为41139。 | Connect to a process via remote KDP server. If no UDP port is specified, port 41139 is assumed. |
| language | 特定于源语言的命令。 | Commands specific to a source language. |
| log | 控制LLDB内部日志记录的命令。 | Commands controlling LLDB internal logging. |
| memory | 用于操作当前目标进程中的内存的命令。 | Commands for operating on memory in the current target process. |
| platform | 管理和创建平台的命令。 | Commands to manage and create platforms. |

| process | 用于与当前平台上的进程交互的命令。 | Commands for interacting with processes on the current platform. |
| quit | 退出LLDB调试器。 | Quit the LLDB debugger. |
| register | 用于访问当前线程和堆栈帧的寄存器的命令。 | Commands to access registers for the current thread and stack frame. |
| reproducer |
用于操作复制程序的命令。 重新生成程序可以捕获带有所有依赖项的完整调试会话。 生成的复制器用于在调试调试器时重播调试会话。 因为复制器需要从头到尾的整个调试会话，所以您需要以捕获或重播模式启动调试器，通常通过命令行驱动程序。 复制器是不相关的记录重播调试，因为在重播期间您不能与调试器交互。 |
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 | 使用提供的代码调用脚本解释器并显示任何结果。如果没有提供代码，则启动交互式解释器。 | Invoke the script interpreter with provided code and display any results. Start the interactive interpreter if no code is supplied. |
| settings | LLDB设置管理命令。 | Commands for managing LLDB settings. |
| source | 用于检查由当前目标进程的调试信息描述的源代码的命令。 | Commands for examining source code described by debug information for the current target process. |

Show variables for the current stack frame. Defaults to all arguments and local variables in scope. Names of argument, local, file static and file global variables can be specified. Children of aggregate variables can be specified such as 'var->child.x'. The -> and [] operators in 'frame variable' do not invoke operator overloads if they exist, but directly access the specified element. If you want to trigger operator overloads use the expression command to print the variable instead. It is worth noting that except for overloaded operators, when printing local variables 'expr local_var' and 'frame var local_var' produce the same results. However, 'frame variable' is more efficient, since it uses debug information and memory reads directly, rather than parsing and evaluating an expression, which may even involve JITing and running code in the target program. |
