问题描述

我目前使用的/串/ new_string / g的来通过一些的CSV文件,但是我运行到在以下情况下难度:

I'm currently using 's/string/new_string/g' to go through some CSV files, however I'm running into difficulty in the following scenario:

我要替换192.168.0.11的实例,但它也赶上192.168.0.111的实例

I want to replace instances of '192.168.0.11', however it's also catching instances of '192.168.0.111'.

我怎样才能确保SED只待价而沽192.168.0.11,而不是192.168.0.111?我显然有重复这对于很多变数,所以一些易于扩展将AP preciated。

How can I ensure sed only grabs '192.168.0.11' and not '192.168.0.111'? I'll obviously have to repeat this for many variables, so something easily scalable would be appreciated.

谢谢!

推荐答案

我不知道你正在使用正则表达式是,但如果你想192.168.0.11的精确匹配,你可以使用:
S / \\< 192 \\ .168 \\ .0 \\ 0.11 \\> //摹

I'm not sure what the regex you are using is, but if you want an exact match of '192.168.0.11' you can use: s/\<192\.168\.0\.11\>//g
