awk - 如何在 AWK 中替换正则表达式？

Question

用 AWK 脚本替换正则表达式的最简单方法是什么？
我的目标是搜索模式：

/a|b/

在句子中：

I read a book "GAWK: Effective AWK Programming", but I can not figure it out.

并将其替换为：

ABC/a|b/ABC

所以结果将是：

I reABCaABCd ABCaABC ABCbABCook "GAWK: Effective AWK ProgrABCaABCmming", but I cABCaABCn not figure it out.

Answer 1

您可以尝试：

$ awk '{ gsub(/[ab]/,"ABC&ABC")}1' file 
I reABCaABCd ABCaABC ABCbABCook "GAWK: Effective AWK ProgrABCaABCmming", ABCbABCut I cABCaABCn not figure it out.

文件在哪里：

I read a book "GAWK: Effective AWK Programming", but I can not figure it out.
