查找信用卡号并在设定位置替换字符

Question

我有一个包含信用卡号码（16个字符）的文件，我想找到它们并用＆＃34; X＆＃34;除了前6个和后4个数字。

sed -i 's/\([345]\{1\}[0-9]\{3\}\|6011\)\{1\}[ -]\?[0-9]\{4\}[ -]\?[0-9]\{2\}[-]\?[0-9]\{2\}[ -]\?[0-9]\{1,4\}/\XXXXXX/g' foobar.csv

将轻松找到文件中包含的所有信用卡，并将其替换为＆＃34; XXXX＆＃34;

但是我想找到信用卡并用＃34; X＆＃34;替换字符串中的字符串7-12，因此该文件将包含像123456XXXXXX7890这样被屏蔽的信用。

示例输入行：

jam peanut boat handbag on the shore in Tuesday 4548640040302006 in the morning jimmy

示例输出行：

jam peanut boat handbag on the shore in Tuesday 454864XXXXXX2006 in the morning jimmy

Answer 1

尝试使用GNU sed来匿名化信用卡号码：

sed -i 's/\(\([345]\{1\}[0-9]\{3\}\|6011\)\{1\}[ -]\?[0-9]\{2\}\)[0-9]\{2\}[ -]\?[0-9]\{2\}[-]\?[0-9]\{2\}[ -]\?\([0-9]\{1,4\}\)/\1XXXXXX\3/g' file

输入：

jam peanut boat handbag on the shore in Tuesday 4548640040302006 in the morning jimmy
jam peanut boat handbag on the shore in Tuesday 454864XXXXXX2006 in the morning jimmy

输出到文件：

jam peanut boat handbag on the shore in Tuesday 454864XXXXXX2006 in the morning jimmy
jam peanut boat handbag on the shore in Tuesday 454864XXXXXX2006 in the morning jimmy
