问题描述
我正在关注生成 SSH 密钥，它说
sudo apt-get install xclip
下载并安装 xclip.如果您没有 apt-get，您可能需要使用其他安装程序(例如 yum)
Downloads and installs xclip. If you don't have apt-get, you might need to use another installer (like yum)
xclip -sel 剪辑 <~/.ssh/id_rsa.pub
将 id_rsa.pub 文件的内容复制到剪贴板
Copies the contents of the id_rsa.pub file to your clipboard
但是在我运行后xclip -sel clip <~/.ssh/id_rsa.pub 我得到 Error: Can't open display: (null)问题是什么?我用谷歌搜索，但一无所获
But after I runxclip -sel clip < ~/.ssh/id_rsa.pub I get Error: Can't open display: (null)What is the problem? I googled around but found nothing about it
推荐答案
DISPLAY=:0 xclip -sel clip <~/.ssh/id_rsa.pub 对我不起作用(ubuntu 14.04)，但你可以使用:
DISPLAY=:0 xclip -sel clip < ~/.ssh/id_rsa.pub didn't work for me (ubuntu 14.04), but you can use :
cat ~/.ssh/id_rsa.pub
获取你的公钥
