如何使用grep匹配双引号

Question

I thought I knew this(or at least how to google for it)!

But I can't figure out how to match double quotes using grep when searching for patterns in text file. I tried to escape the double quotes symbol with a backslash, but it doesn't seem to work.

>cat trial.txt  
"Bill" is here and "Ben" is there

> grep -iE "and \"ben\" is" trial.txt
Unmatched ".

How do I get this to work?

使用单引号来考虑每个字符的字面含义。

grep 'and "Ben" is' trial.txt
