是否可以在vim中替换匹配的模式？

Question

Every time before I replace pattern1 with pattern2 , I usually use /pattern1 to confirm the regex is the right one. When doing the actual substitution, however, I have to use :%s/pattern1/pattern2/g (Suppose I need to do the global replacement). This is annoying and may fail due to typos.

So is there a convenient way to substitute the matched pattern1 ?

Answer 1

// is last search :%s//replacement/g will do what you want.

however you could also think about %s/pattern1/pattern2/gc or %s/p1/p2/gn

Answer 2

The null string in the first half of the s command defaults to the last searched pattern.

So

g/fred/s//mary/g

changes all instances of fred to mary.

Answer 3

只需使用一个空模式：

:%s//pattern2/g

Answer 4

I think that:

:.,.+3s//repl/g

should replace every occurence of the current pattern in the next 3 lines with repl.

Answer 5

您可以使用:%s/pattern/replace/c （注意尾随c ），vim会要求您进行确认。
