ngrep如何使匹配表达式不区分大小写？

Question

从手册页引用

match expression
A  match  expression  is either an extended regular expression, or if the -X
option is specified, a string signifying a hexadecimal value.   An  extended
regular  expression  follows  the  rules  as  implemented  by  the GNU regex
library.  Hexadecimal expressions can optionally be preceded by `0x'.  E.g.,
`DEADBEEF', `0xDEADBEEF'.

对于（e）grep，我使用-i，但是如何写一个不区分大小写的ngrep匹配表达式？

e.g。

sudo ngrep -xqtd lo0 select port 3306

不匹配mysql --protocol=tcp -e "Select 1"？
