须藤回声＆QUOT;东西＆QUOT; ＆GT;＆GT;在/ etc / privilegedFile不工作...是否有别的选择吗？ [英] sudo echo "something" >> /etc/privilegedFile doesn't work... is there an alternative?

问题描述

这是一个pretty简单的问题，至少现在看来似乎应该是，大约在Linux中sudo的权限。

This is a pretty simple question, at least it seems like it should be, about sudo permissions in Linux.

有很多时候，我只是想将一些东西附加到 / etc / hosts中或类似的文件，但最终没有能够因为两个＆GT; 和＆GT;方式＆gt; 是不允许的，即使有根

There are a lot of times when I just want to append something to /etc/hosts or a similar file but end up not being able to because both > and >> are not allowed, even with root.

有什么方法来完成这项工作，而无需苏或须藤苏成根？

Is there someway to make this work without having to su or sudo su into root?

推荐答案

使用三通：

echo 'deb blah # blah' | sudo tee --append /etc/apt/sources.list

请一定要避免引号内的报价。

Make sure to avoid quotes inside quotes.

要避免打印数据传回控制台：

To avoid printing data back to the console:

echo 'deb blah # blah' | sudo tee --append /etc/apt/sources.list > /dev/null
