命令缩写
lldb命令的缩写:所有命令都支持任意前缀字符的缩写,只要不产生混淆
lldb中的命令,可以缩写
比如:
print
常见缩写是:
p
但其实底层逻辑是:
从第一个字母p到最后一个字母t,缩写到任意位置都是可以的
前提是,只要不(和其他命令的前缀)产生混淆
举例
printp- 是
lldb专门为print保留的p,所以可以用p- 否则按道理,也会和其他
process等命令产生冲突,也不能把print缩写为p
- 否则按道理,也会和其他
- 是
pr- 和
process的pr是一样的前缀字符lldb无法确定是哪个,所以就属于会产生冲突、混淆- 所以不能用
pr
- 和
pri- 可以
prin- 可以
print- 可以 所以总体结论就是:
print- 可以用特定的缩写:
p - 也可以用其他普通的,不产生冲突的缩写:
pri、prin、print
- 可以用特定的缩写:
breakpoint
断点de的命令
breakpoint
可以缩写/简写为:
breakpoin
breakpoi
breakpo
breakp
break
brea
bre
br
而不能用:
b- 特殊:属于lldb中专门保留的特定的缩写
- 含义是:以某种特定的格式去添加断点
- 特殊:属于lldb中专门保留的特定的缩写
-》有了上面的缩写逻辑,则普通的:
breakpoint list
就可以写为:
breakpoin list
breakpoi list
breakpo list
breakp list
break list
brea list
bre list
br list
都是可以的,都是等价的
子命令也支持缩写
当然命令的子命令,参数,也是同样支持缩写
比如此处
br list
的list也可以缩写:
br lis
br li
br l
只要不产生冲突即可
此处就是breakpoint的子命令中,上述缩写不会冲突混淆即可。
注:
此处可以用help breakpoint去查看,breakpoint有哪些子命令
(lldb) help breakpoint
Commands for operating on breakpoints (see 'help b' for shorthand.)
Syntax: breakpoint <subcommand> [<command-options>]
The following subcommands are supported:
clear -- Delete or disable breakpoints matching the specified source
file and line.
command -- Commands for adding, removing and listing LLDB commands
executed when a breakpoint is hit.
delete -- Delete the specified breakpoint(s). If no breakpoints are
specified, delete them all.
disable -- Disable the specified breakpoint(s) without deleting them. If
none are specified, disable all breakpoints.
enable -- Enable the specified disabled breakpoint(s). If no breakpoints
are specified, enable all of them.
list -- List some or all breakpoints at configurable levels of detail.
modify -- Modify the options on a breakpoint or set of breakpoints in
the executable. If no breakpoint is specified, acts on the
last created breakpoint. With the exception of -e, -d and -i,
passing an empty argument clears the modification.
name -- Commands to manage name tags for breakpoints
read -- Read and set the breakpoints previously saved to a file with
"breakpoint write".
set -- Sets a breakpoint or set of breakpoints in the executable.
write -- Write the breakpoints listed to a file that can be read in
with "breakpoint read". If given no arguments, writes all
breakpoints.
For more help on any particular subcommand, type 'help <command> <subcommand>'.
其中可见,breakpoint的子命令:
clearcommanddeletedisableenablemodifynamereadsetwrite
不会和上面的缩写lis、li、l,有冲突和混淆
-》所以你会看到,很多人常把:
breakpoint list
写成:
br l
就是这个目的:
- 尽量用缩写
- -》减少输入的字符数
- -》提高调试效率
- -》减少输入的字符数
其他常见缩写
其他常用缩写:
expression->e、expbreakpoint=br== 特殊写法:bbreakpoint set->br sbreakpoint list->br l- 举例
breakpoint delete 1->br del 1breakpoint disable 1->br dis 1breakpoint enable 1->br en 1breakpoint set --name main->br s -n main->b mainbreakpoint set --name foo --condition '(int)strcmp(y,"hello") == 0'- ->
br s -n foo -c '(int)strcmp(y,"hello") == 0'
- ->
disassemble->dis- 举例
disassemble -s 0x1167b1974->dis -s 0x1167b1974
- 举例
register->regregister read->reg r- 举例
register r x0->reg r x0
- 举例
image->imimage lookup=im loo- 举例
image lookup --address 0x1ec4->im loo -a 0x1ec4
- 举例
memory->mem
