基于正则表达式的匹配和替换与纳米? [英] Regex-based matching and sustitution with nano?

问题描述

我知道 nano 的搜索和替换功能，但它是否能够使用正则表达式进行匹配和替换(特别是使用匹配的一部分的替换)?如果是这样，您能否提供一些使用的语法示例(用于匹配和替换)?

I am aware of nano's search and replace functionality, but is it capable of using regular expressions for matching and substitution (particularly substitutions that use a part of the match)? If so, can you provide some examples of the syntax used (both for matching and replacing)?

我开始学习 Perl 风格的正则表达式，但我发现文本编辑器有时会提出自己的语法.

I cut my teeth on Perl-style regular expressions, but I've found that text editors will sometimes come up with their own syntax.

推荐答案

您需要在全局 nanorc 文件中添加或取消注释以下条目(在我的机器上，它是 <代码>/etc/nanorc):

You need to add, or un-comment, the following entry in your global nanorc file (on my machine, it was /etc/nanorc):

set regexp

然后启动一个新终端并按 CTRL + / 并进行替换，现在应该可以识别正则表达式.

Then fire up a new terminal and press CTRL + / and do your replacements which should now be regex-aware.

搜索conf->(S+):

替换为1_conf

按 a 替换所有出现的:

Press a to replace all occurrences:
