计算 Vim 中的出现次数而不标记缓冲区已更改 [英] Counting occurrences in Vim without marking the buffer changed

问题描述

为了知道模式在当前缓冲区中存在多少次，我这样做:

In order to know how many times a pattern exists in current buffer, I do:

:%s/pattern-here/pattern-here/g

它给出了模式出现的次数，但显然很麻烦，而且还有设置已更改"状态的副作用.

It gives the number of occurrences of the pattern, but is obviously cumbersome and also has the side-effect of setting the 'changed' status.

有没有更优雅的计数方式?

Is there a more elegant way to count?

推荐答案

为避免替换，将第二个模式留空，并添加n"标志:

To avoid the substitution, leave the second pattern empty, and add the "n" flag:

:%s/pattern-here//gn

这被描述为官方提示.
