shorthand.)

command alias hp help. 用hp 替换help命令
disassemble --显示汇编代码 d di dis 等缩写都可以
expression -- 显示变 量的值
ex n
frame :
info 用法 frame info 显示一些当前线程信息
select frame select 显示当前调试线程位置信息
variable frame var 显示当前调试线程局部变量信息
kdp-remote -- Connect to a process via remote KDP server. If no UDP
port is specified, port 41139 is assumed.
language -- Commands specific to a source language.
log -- Commands controlling LLDB internal logging.
memory --操作当前进程内存 mem read &result 读取变量result中的值 mem read -c 100 &result 显示100字节
platform -- Commands to manage and create platforms.
plugin -- lldb插件管理
process -- Commands for interacting with processes on the current
platform.
quit -- 退出lldb
register -- 读写寄存器值
script -- Invoke the script interpreter with provided code and
display any results. Start the interactive interpreter
if no code is supplied.
settings -- Commands for managing LLDB settings.
source -- 通过调试信息展示源文件信息
target -- Commands for operating on debugger targets.
thread -- Commands for operating on one or more threads in the
current process.
type -- Commands for operating on the type system.
version -- Show the LLDB debugger version.
watchpoint -- Commands for operating on watchpoints.
Current command abbreviations (type 'help command alias' for more info):
add-dsym --增加符号表
attach -- 附加进程
b 设置断点
bt 显示当前栈信息，frame中有的命令功能相同
c 继续运行当前进程中的所有线程
call 直接调用表达示 比如 call 1+1
continue -- Continue execution of all threads in the current process.
detach -- Detach from the current target process.
di dis 显示反汇编代码
display -- Evaluate an expression at every stop (see 'help target
stop-hook'.)
down -- Select a newer stack frame. Defaults to moving one frame, a
numeric argument can specify an arbitrary number.
env -- Shorthand for viewing and setting environment variables.
exit -- 退出
f -- Select the current stack frame by index from within the current
thread (see 'thread backtrace'.)
file -- Create a target using the argument as the main executable.
finish -- Finish executing the current stack frame and stop after
returning. Defaults to current thread unless specified.
image -- Commands for accessing information for one or more target
modules.
j -- Set the program counter to a new address.
jump -- Set the program counter to a new address.
kill -- Terminate the current target process.

into a function whose name matches the TargetFunctionName.
step -- Source level single step, stepping into calls. Defaults to
current thread unless specified.
