Perl +仅当匹配行中的两个单词时，一行才更改字符串

发布于 2024-10-06 10:02:38 字数 319 浏览 3 评论 0原文

我的文件中有以下行，

    <getTheIP ConnectType='INFO' Host='machine_num_1' VirtualIp='12.34.3.9'/>

我需要将 IP 12.34.3.9 更改为其他 IP，例如 3.4.5.6 但前提是我的第一个单词匹配 ConnectType 和第二个单词匹配 machine_num_1

请告知我如何使用 perl 单行命令来做到这一点（我需要运行这个bash 脚本中的 perl 行命令）

I have the following line in file

    <getTheIP ConnectType='INFO' Host='machine_num_1' VirtualIp='12.34.3.9'/>

I need to change the IP 12.34.3.9 to other IP for example 3.4.5.6
but only if I have in line the first word match ConnectType and the second word match machine_num_1

Please advice how I can do that with perl one line commnand ( I need to run this perl line command from bash script)
