Question

I have a textfile like so:

marc_webber
john_grisham
rahmin_darfur
firstname_lastname

我希望这一产出也一样(如“万象”这样的双重名称):

Webber, Marc, marc_webber
Grisham, John, john_grisham
Darfur, Rahmin, rahmin_darfur
LastName, FirstName, firstname_lastname

So I want to split the strings at the _, move the last name to the beginning and comma delimit first name and the concatenated name to the end (and maybe even capitalize the first letter). This would be fairly easy with a programming language, but I want to know whether it is possible using Notepad++ s find and replace feature with regular expressions.
Basically I would need to create variables for the first name and the last name and string them together again in the end.

Answer 1

除临时工作外(在方案设计师笔记本中测试......):

Find Pattern:

((w+)_(w+))

<>Replace>:

3, 2, 1

Answer 2

这对我来说是使用<代码>的<>。 (我猜测,由于可能支持常规表述,它也在附注pad++中工作):

$ sed -r  s/(w+)_(w+)/u2, u1, /  file.txt
Webber, Marc, marc_webber
Grisham, John, john_grisham
Darfur, Rahmin, rahmin_darfur
Lastname, Firstname, firstname_lastname

实现资本化,如你的例子,是使用<代码>u<>/代码>。

详情请见。
