例如，我必须找到以10.191 ||开头的IP。 10.192 || 10.193 || 10.194

现在我正在使用以下代码查找特定的IP ruby.file

file_path = './file.txt'
string = '10.195.0.168'
File.open(file_path) do |f|
    f.readlines.each { |line|
        if line[string]
            puts line
            puts string
        end
    }
end

Answer 1

您可以使用此正则表达式查找您以开头的所有IP，“ IP开头为10.191 || 10.192 || 10.193 || 10.194” ，

\b10\.19[1-4]\.\d+\.\d+

Answer 2

您可以使用grep。

puts File.readlines("file.txt").grep(/ 10\.19[1-4][^\s]+ /)
