本文提供了一种在没有编辑权限的情况下，使用 Vim 保存文件的方法。通过使用 `:w! sudo tee` 命令，可以在不需要 sudo 权限的情况下将修改的内容保存到目标文件中，从而避免了常见的 ‘E212: Can’t open file for writing’ 错误。

Save a file you edited in vim without the needed permissions (no echo)

Write a file you edited in Vim but that you do not have the permissions to write to (unless you use sudo.) Same as #1204 but without the echo to stdout that I find annoying.

不用sudo等来保存一个需要编辑权限的文件，保存一个你在写的文件文件，你发现你没有权限去写（除非你用sudo），此时使用下面的命令就可以解决

下面的命令解释，写文件到一个命令，tee读取stdin，写到stdout和文件中，由于使用了sudo，所以可以写回文件，个人测试不用>/dev/null也可以直接就stdout到文件了

:w !sudo tee > /dev/null %

文章评论部分：

:w !sudo tee %

Save a file you edited in vim without the needed permissions

I often forget to sudo before editing a file I don't have write permissions on. When you come to save that file and get the infamous "E212: Can't open file for writing", just issue that vim command in order to save the file without the need to save it to a temp file and then copy it back again.

command W :execute ':silent w !sudo tee % > /dev/null' | :edit!

Save a file you edited in vim without the needed permissions

Calls sudo tee like all the other lines, but also automatically reloads the file.

Optionally you can add

command Wq :execute ':W' | :q

and

command WQ :Wq

to make quitting easier
