Question

我有以下字符串

Local intf     Local circuit              Dest address    VC ID      Status
-------------  -------------------------- --------------- ---------- ----------
Gi36/1         Eth VLAN 3018              181.181.181.181 3018       UP

我想替换包含＆＃34; linuxserver＆＃34;等字符的所有行。在它。

我在下面的vi中尝试过。

:%s/.*linuxserver.*//g

但是，在更换之后，我的输出为

    Local intf     Local circuit              Dest address    VC ID      Status
    -------------  -------------------------- --------------- ---------- ----------
    Gi36/1         Eth VLAN 3018              181.181.181.181 3018       UP
    10.65.220.180#
    --- 19:58:22 ---
    //A new line here
    //A new line here
    //A new line here    
    //A new line here    
    +++ 19:58:22 +++
    Local intf     Local circuit              Dest address    VC ID      Status

我希望它如下所示，

Local intf     Local circuit              Dest address    VC ID      Status
    -------------  -------------------------- --------------- ---------- ----------
    Gi36/1         Eth VLAN 3018              181.181.181.181 3018       UP
    10.65.220.180#

    Gi36/1         Eth VLAN 3018              181.181.181.181 3018       UP

我怎么能做到这一点？提前谢谢。

Answer 1

尝试：

:g/linuxserver/d

见

:help global

了解更多信息。

Answer 2

:global命令最适合您的问题（:g/linuxserver/d），但这就是为什么vim为您提供空行而不是删除它们的原因。 .与新行不匹配（请参阅:help :regex）：

.   (with 'nomagic': \.)                */.* */\.*
    Matches any single character, but not an end-of-line.

\n  matches an end-of-line              */\n*
    When matching in a string instead of buffer text a literal newline
    character is matched.

因此，为了删除这些行，请按以下步骤更改正则表达式：

:%s/.*linuxserver.*\n//

哦，/g修饰符在你的情况下没有意义，因为你已经匹配整行（.* ... .*）。

使用vim中的regex替换字符和换行符
