使用GSUB替换为两个双引号双引号？ [英] Using gsub to replace a double quote with two double quotes?

问题描述

我试着写AWK的脚本（除其他事项外）取代了双引号的所有实例有两个连续的双引号。但由于某些原因，我似乎无法正确地逃过我的双引号。

I'm trying write a script in awk that (among other things) replaces all instances of double quotes with two consecutive double quotes. But for some reason, I can't seem to escape my double quotes properly.

因此​​，例如：

Mary had a "little" lamb

将成为

Mary had a ""little"" lamb

感谢好心！

推荐答案

您可以做到这一点是这样的：

You can do it like this:

echo 'Mary had a "little" lamb' | awk '{ gsub(/"/, "&&") } 1' 

输出：

Mary had a ""little"" lamb

的 1 末调用awk的默认块 {$打印0} 。

The 1 at the end invokes awk's default block { print $0 }.

它甚至与SED短：

echo 'Mary had a "little" lamb' | sed 's/"/&&/g'
