如何逃避awk的单引号里面的printf [英] how to escape single quote in awk inside printf

问题描述

我要做到以下

awk 'BEGIN {FS=" ";} {printf "'%s' ", $1}'

但逃逸单引号这样不起作用

But escaping single quote this way does not work

awk 'BEGIN {FS=" ";} {printf "\'%s\' ", $1}'

如何做到这一点？感谢您的帮助。

How to do this? Thanks for help.

推荐答案

这或许你要找的是什么：

This maybe what you're looking for:

awk 'BEGIN {FS=" ";} {printf "'\''%s'\'' ", $1}'

也就是说，'\\''关闭打开的 ，然后打印文字 通过转义它最后打开 。

That is, with '\'' you close the opening ', then print a literal ' by escaping it and finally open the ' again.
