我问了一个问题，将字符串插入到文本文件中的列表变量中[使用 sed]

其中@RomanPerekhrest 向我展示了不同的正则表达式语法。

\(=([^)]*\))可以捕获[^)]*为组 1 。这让我很困惑。

这\(([^\)]*)\)在我看来是正确的，但它在 sed 中被破坏了。

所以我想知道如何让 sed 使用正则表达式语法标准作为 python 或 javascript（许多语言的通用标准）。

我想通过脚本添加zsh-autosuggestions插件。~/.zshrc

原文：

plugins=(git)

或者

 plugins=(git
 some1
 some2)

目标 ：

plugins=(git
zsh-autosuggestions)

  1. 这行不通。

    sed -i  's/^plugins=\(([^\)]*)\)/plugins=\(\1\nzsh-autosuggestions\n\)/' ~/.zshrc

    我很困惑，我认为这([^\)]*) 是第 1 组，但为什么它不起作用

  2. 但删除第一组() 

    sed -i  's/^plugins=\([^\)]*\)/plugins=\(\1\nzsh-autosuggestions\n\)/' ~/.zshrc

    结果是

    plugins=((git
zsh-autosuggestions
)
)

    我已经逃脱了()by \，为什么它变成了第 1 组？

  1. 我以前ssh-copy-id root@c199成功过。
  2. 我可以在ssh root@c199没有密码提示的情况下登录
  3. 我想由另一个用户自动登录ufo （远程机器有这个用户）

  4. ssh-copy-id ufo@c199 问我输入密码，

    /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
ufo@c199's password:

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'ufo@c199'"
and check to make sure that only the key(s) you wanted were added.

  5. 但是通过ssh ufo@c199仍然提示输入密码登录。

我尝试通过 ssh 在 msys2（在 Windows 上）上登录远程 centos，我发现有很多相同的行，例如

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCs7RTfvn83Rxdmvgfh+F4kUlM5FzIUb9rRHaqq11xKIW1gztn/+G4tr+OWl4o6GTW2Z361hIi

zEQOMi6S9zM/yRiD0XZrbmzYfNkoXA03WTmMR/DynVvX2nV /c/Users/xxxx/.ssh/id_rsa

在 centos 中/home/ufo/.ssh/authorized_keys，

我已将 .ssh 用户的文件夹权限更改为 700 并将 authorized_keys 文件更改为 644 。

相同的ssh密钥，无提示ssh root@c199登录，但ssh ufo@c199提示输入密码..

更新

ssh ufo@c199 -vv输出：
