  • 工作学习 / IT技术讨论 / 再说一个面世时曾经被问的问题 -guest:guest; 2001-4-10 {258} (#43252@0)
    有一段文本，例如

    I'm a student
    I lived in Canada,
    I don't like this stupid country,
    but I'd like to live here.

    用一个vi命令，把它变成
    I'm a student
    I lived in Canada,
    I don't like this stupid country,
    but I'd like to live here.

      用一个vi命令，把它变成
      __I'm a student
      __I lived in Canada,
      __I don't like this stupid country,
      but I'd like to live here.

      __代表空格
      • 1,$s/^/^_/ （ _代表空格） -pasu(InTheSky); 2001-4-10 (#43262@0)
        • 第2个^多于了吧？ -guest:guest; 2001-4-10 {38} (#43267@0)
          当时我是没回答上，不过工作还是找到了。
          • 面试嘛，安全起见，呵呵，我也记不清了，因为好久没有用了。看来我们是同行，注册个ID吧，咱们多交流交流。 -pasu(InTheSky); 2001-4-10 (#43340@0)

      • :1,$s/^I/_I/g -hotpot(麻辣烫); 2001-4-10 (#43276@0)
        • you're right. 忘了看but那句不用改了。 -pasu(InTheSky); 2001-4-10 (#43343@0)
      • I should be : 1, $ s/^I/ I/ -lumlumq(lumlum); 2001-4-11 (#44005@0)
    • 什么命令也不用，呵呵，这不是一样的嘛！ -pasu(InTheSky); 2001-4-10 (#43257@0)
      • Sorry. a simple question: where should I input these characters "$s/^/^_/ "? In EDIT mode or some other modes? tks. -howru(How are you?); 2001-4-11 (#43993@0)
        • Press Esc, and then press Enter. "1,$" means apply the following command from the first line to the last line. Don't break it into two parts. -pasu(InTheSky); 2001-4-11 (#43997@0)
