regex - vim 正则表达式 : deleting character based on position

Question

这类似于问题VIM: insert or delete data based on position

我试图在文件中每一行的位置 7 处替换(而不仅仅是插入)所需的文本。根据上述问题的解决方案中提供的正则表达式，我尝试了:

a. %s/\%=7c/text/  (failed error message - illegal character)
b. %s/\%7c/text/g   (says correct amount of lines / changes were made BUT blank space is still there after "text")
c. %s/\%7c/text/ (same as b)

Answer 1

/%7c 将插入到字符 7

您希望匹配如下，以便它包含下一个字符:

%s/\%7c./text/
