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
print
p
- 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:
clear
command
delete
disable
enable
modify
name
read
set
write
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
、exp
breakpoint
=br
== 特殊写法:b
breakpoint set
->br s
breakpoint list
->br l
- 举例
breakpoint delete 1
->br del 1
breakpoint disable 1
->br dis 1
breakpoint enable 1
->br en 1
breakpoint set --name main
->br s -n main
->b main
breakpoint 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
->reg
register read
->reg r
- 举例
register r x0
->reg r x0
- 举例
image
->im
image lookup
=im loo
- 举例
image lookup --address 0x1ec4
->im loo -a 0x1ec4
- 举例
memory
->mem
