用于在 vim 中搜索和替换的正则表达式
问题描述：
我有一个包含多个条目的文件，如下所示:
I have a file which has multiple entries like this:
Abcd:abcd:*sometext*:klm:xyz/abc
Abcd:abcd:R%fs90uw:klm:xyz/abc
现在，我想将klm"替换为qrs"，仅用于那些行中包含sometext"字符串的行.
Now, I want to replace "klm" with "qrs" for only those lines which have the "sometext" string in the line.
如何使用 vim 中的搜索和替换功能执行此操作?
How can I do this using the search and replace feature in vim?
谢谢！

:g 是你的朋友:
:g/sometext/s/klm/qrs/g
