使用vim編輯檔案時遇到沒有許可權的解決辦法

Save a file you edited in vim without the needed permissions (no echo)原文地址：http://www.commandlinefu.com/commands/view/5147/save-a-file-you-edited-in-vim-without-the-needed-permissions-no-echoSave 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等來儲存一個需要編輯許可權的檔案，儲存一個你在寫的檔案檔案，你發現你沒有許可權去寫（除非你用sudo），此時使用下面的命令就可以解決

下面的命令解釋，寫檔案到一個命令，tee讀取stdin， 寫到stdout和檔案中，由於使用了sudo，所以可以寫迴文件，個人測試不用>/dev/null也可以直接就stdout到檔案了:w !sudo tee > /dev/null %文章評論部分：: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
