Append to /etc/apt/sources.list
提问by RyanScottLewis
I'm creating some scripts to streamline application installations and I need to append to the end of /etc/apt/sources.list
我正在创建一些脚本来简化应用程序安装，我需要附加到 /etc/apt/sources.list 的末尾
This code below append to files in ~ but not in /etc/apt/
下面的代码附加到 ~ 中的文件，但不在 /etc/apt/ 中
echo "deb http://ppa.launchpad.net/person/ppa/ubuntu karmic main" >> /etc/apt/sources.list

This will work:
这将起作用：
sudo sh -c "echo 'deb http://ppa.launchpad.net/person/ppa/ubuntu karmic main' >> /etc/apt/sources.list"
However, instead of editing /etc/apt/sources.list, it is simpler to add a new *.listfile to /etc/apt/sources.list.d.
但是，与编辑 相比/etc/apt/sources.list，将新*.list文件添加到/etc/apt/sources.list.d.
For example,
例如，
echo 'deb http://ppa.launchpad.net/person/ppa/ubuntu karmic main' >/tmp/myppa.list sudo cp /tmp/myppa.list /etc/apt/sources.list.d/ rm /tmp/myppa.list

make sure to have a backup file
确保有备份文件
echo "foo" | sudo tee -a /etc/apt/sources.list
However, I would reallyrecommend you create a new .list and then use this method to append, store it in /etc/apt/sources.list.d/
但是，我真的建议您创建一个新的 .list，然后使用此方法进行附加，将其存储在/etc/apt/sources.list.d/
