lldb 的帮助系统是回答此类问题的好方法：

(lldb) help command
     Commands for managing custom LLDB commands.

Syntax: command <subcommand> [<subcommand-options>]

The following subcommands are supported:

      alias   -- Define a custom command in terms of an existing command.  Expects 'raw' input (see 'help raw-input'.)
      delete  -- Delete one or more custom commands defined by 'command regex'.
      history -- Dump the history of commands in this session.
                 Commands in the history list can be run again using "!<INDEX>".   "!-<OFFSET>" will re-run the command that is <OFFSET> commands from the end of the list (counting the current command).
      regex   -- Define a custom command in terms of existing commands by matching regular expressions.
      script  -- Commands for managing custom commands implemented by interpreter scripts.
      source  -- Read and execute LLDB commands from the file <filename>.
      unalias -- Delete one or more custom commands defined by 'command alias'.

For more help on any particular subcommand, type 'help <command> <subcommand>'.

command source 看起来很有希望：

(lldb) help command source 
     Read and execute LLDB commands from the file <filename>.

Syntax: command source <cmd-options> <filename>

Command Options Usage:
  command source [-e <boolean>] [-c <boolean>] [-s <boolean>] <filename>

       -c <boolean> ( --stop-on-continue <boolean> )
            If true, stop executing commands on continue.

       -e <boolean> ( --stop-on-error <boolean> )
            If true, stop executing commands on error.

       -s <boolean> ( --silent-run <boolean> )
            If true don't echo commands while executing.

     This command takes options and free-form arguments.  If your arguments resemble option specifiers (i.e., they start with a - or --), you must use ' -- ' between the end of the command options and the beginning of the arguments.

还有一个apropos 命令将在帮助中搜索关键字。不幸的是，apropos command 返回的点击次数过多，对您的情况特别有用。 apropos file 的噪音要小一些，但仅查看命令子命令可能是最简单的。 help 不带参数将列出顶级命令，这也可能有助于您入门。

注意，当你从命令行启动它时，你也可以告诉 lldb 获取一个随机的命令文件（使用-s 选项）。要了解有关 lldb 命令行选项的更多信息，请运行：

 > lldb --help
