问题描述

What do f and t commands do in vim and exactly how they work?

推荐答案

遇到此类问题的第一站应该是 vim 的内部帮助，:h f 和 :h t.但是，在这种情况下，如果没有示例，这些条目有点神秘.假设我们有这一行(^ = 光标位置):

Your first stop with questions like these should be vim's internal help, :h f and :h t. However, in this case, those entries are a bit cryptic without an example. Suppose we had this line (^ = cursor position):

The quick brown fox jumps over the lazy dog.
^

这些命令在一行中查找字符.所以 fb 会将光标放在此处:

These commands find characters on a line. So fb would place the cursor here:

The quick brown fox jumps over the lazy dog.
          ^

t 与 f 类似，但将光标放在前面的字符上.所以 tb 会给你:

t is like f but places the cursor on the preceding character. So tb would give you:

The quick brown fox jumps over the lazy dog.
         ^

您可以将这些命令记为 find 和 till.此外，您可以在命令前添加一个数字以移动到该字符的第 n 个出现处.例如，3fb 将移动到光标右侧的第三个 b.我的例句只有一个b，所以光标根本不会移动.

You can remember these commands as find and till. Also, you can prepend the commands with a number to move to the nth occurrence of that character. For example, 3fb would move to the third b to the right of the cursor. My example sentence only has one b though, so the cursor wouldn't move at all.
