文本替换字符串，搞不定了还是要向大佬们学习一下

mir620

{"hostname": "host1", "ip": "192.168.1.1", "username": "zzz", "password": "zzz", "ssh_port": 22},
{"hostname": "host2", "ip": "192.168.1.2", "username": "zzz", "password": "zzz", "ssh_port": 22},
{"hostname": "host3", "ip": "192.168.1.3", "username": "zzz", "password": "zzz", "ssh_port": 22}


想把用户名替换为：aaa
密码替换为：bbb
端口为：2222
账号密码端口不是固定的

ip 比较好用正则匹配已经知道咋搞了

还有最后一个字段，在做端口替换的时候，最后一行没有, 号

哎，多少年了，还是学艺不精。需要想大佬们学习啊

legs

1. perl -pe's#username": "\K[^"]+(.*?word": ")[^"]+(.*?port": )\d+#aaa$1bbb${2}2222#'

复制代码

daixubinbin

1. awk 'gsub(/22}/,"2222}"){$6="\"aaa\",";$8="\"bbb\","}6' test

方法还是不错的，但是。端口号、用户名、密码都不是固定的。

方案不错，厉害了但是这个perl命令最新化安装的操作系统不带这个命令，如果要使用的话，还必须安装，但是客户的环境系统平台  千千万，客户不可能为了咋。去安装这个命令。而且有些金融行业。还没有网络。 想要都适配还是非常困难的
不过还是谢谢，大佬。牛逼
