Question

我的初始档案是

192.168.210.12
192.168.210.13
192.168.210.14
192.168.210.15
192.168.210.16
192.168.210.17
192.168.210.18
192.168.210.18

替换模式为%s/\(192.168.210.[0-9]\+\)/\"ssh\ myuser@\1\ -i\ ~\/Documents\/my_key\"/g

运行上面的命令后，我得到了以下文件。

"ssh myuser@192.168.210.12 -i /Documents/my_key"
"ssh myuser@192.168.210.13 -i /Documents/my_key"
"ssh myuser@192.168.210.14 -i /Documents/my_key"
"ssh myuser@192.168.210.15 -i /Documents/my_key"
"ssh myuser@192.168.210.16 -i /Documents/my_key"
"ssh myuser@192.168.210.17 -i /Documents/my_key"
"ssh myuser@192.168.210.18 -i /Documents/my_key"
"ssh myuser@192.168.210.18 -i /Documents/my_key"

在致电:u然后同样替换之后，我得到以下内容：

"ssh myuser@192.168.210.12 -i "ssh myuser@192.168.210.12 -i /Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.13 -i "ssh myuser@192.168.210.13 -i /Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.14 -i "ssh myuser@192.168.210.14 -i /Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.15 -i "ssh myuser@192.168.210.15 -i /Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.16 -i "ssh myuser@192.168.210.16 -i /Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.17 -i "ssh myuser@192.168.210.17 -i /Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.18 -i "ssh myuser@192.168.210.18 -i /Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.18 -i "ssh myuser@192.168.210.18 -i /Documents/my_key"/Documents/my_key"

再次，我打电话：你和替换，它提供以下输出

"ssh myuser@192.168.210.12 -i "ssh myuser@192.168.210.12 -i "ssh myuser@192.168.210.12 -i /Documents/my_key"/Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.13 -i "ssh myuser@192.168.210.13 -i "ssh myuser@192.168.210.13 -i /Documents/my_key"/Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.14 -i "ssh myuser@192.168.210.14 -i "ssh myuser@192.168.210.14 -i /Documents/my_key"/Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.15 -i "ssh myuser@192.168.210.15 -i "ssh myuser@192.168.210.15 -i /Documents/my_key"/Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.16 -i "ssh myuser@192.168.210.16 -i "ssh myuser@192.168.210.16 -i /Documents/my_key"/Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.17 -i "ssh myuser@192.168.210.17 -i "ssh myuser@192.168.210.17 -i /Documents/my_key"/Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.18 -i "ssh myuser@192.168.210.18 -i "ssh myuser@192.168.210.18 -i /Documents/my_key"/Documents/my_key"/Documents/my_key"
"ssh myuser@192.168.210.18 -i "ssh myuser@192.168.210.18 -i "ssh myuser@192.168.210.18 -i /Documents/my_key"/Documents/my_key"/Documents/my_key"

但是，当我从模式中删除~时（即使用此%s/\(192.168.210.[0-9]\+\)/\"ssh\ myuser@\1\ -i\ \/Documents\/my_key\"/g），它会表现出预期效果。

~上这种不寻常的替换行为的原因是什么。

Answer 1

来自:h :s

magic   nomagic   action   
  ~   \~      replaced with the {string} of the previous substitute  s~
 \~    ~      replaced with ~                                         s/\~

应用于您的替换表达式，~将被替换为先前替换的字符串。

当模式具有波形时，正则表达式在vim中递归替换
