我知道(:%s/apple/orange/g)在vim中的简单搜索和替换命令,我们找到所有'苹果'并用'orange'替换它们.
但是有可能在vim中做这样的事情吗?在文件中找到所有'Wheat'并在跳过下一个单词后添加"store"(如果有的话)?
示例:原始文件内容:
Wheat flour
Wheat bread
Rice flour
Wheat

搜索和替换后:
Wheat flour store

Rice flour

这是使用该global命令的最佳时机.它将命令应用于与给定正则表达式匹配的每一行.
*:g* *:global* *E147* *E148*
:[range]g[lobal]/{pattern}/[cmd]
Execute the Ex command [cmd] (default ":p") on the
lines within [range] where {pattern} matches.

在这种情况下,命令是norm A store和正则表达式wheat.所以把它们放在一起,我们有

现在,您可以使用substitute命令执行此操作,但我发现global更方便,更易读.在这种情况下,你有:
:%s/Wheat.*/& store

意思是:
:%s/ " On every line, replace...
Wheat " Wheat
.* " Followed by anything
/ " with...
& " The entire line we matched
store " Followed by 'store'
