如何在vi / vim编辑器中替换多行中的特定字符串

Question

我在文件中包含以下几行：

|other words in line| abcd_1234.xyz |other words in line|

|other words in line| abcd_2345.xyz |other words in line|

|other words in line| abcd_3456.xyz |other words in line|

|other words in line| abcd_4567.xyz |other words in line|

我想将以上几行更改为

|other words in line| q |other words in line|

|other words in line| q |other words in line|

|other words in line| q |other words in line|

|other words in line| q |other words in line|

我尝试过:%s/abcd*.xyz/q/g，但这似乎不起作用。请任何人建议如何解决此问题。

Answer 1

尝试以下操作：

:%s/(abcd_[0-9]{4}\.xyz)/q/g 

Answer 2

如果我们可以指望有空格和|，那么您可以使用：

:%s/\|(.*)\| (abcd_.*) \|(.*)\|/\1q\3
