以上是我每次在 Ubuntu 16.04 中打开新终端时出现的文本。

我该如何关闭它？我把我的电脑借给了别人，他们把它还回来时，电脑还是这个样子。

答案1

.bashrc您可以通过从终端命令运行以下命令来清除文件中的最后 3 行。该命令将备份您的文件.bashrc，以便.bashrc.bak在出现问题时可以将其移回：

cp ~/.bashrc ~/.bashrc.bak; for i in $(seq 3); do sed -i '$d' ~/.bashrc; done

关闭您的终端，然后当您打开一个新终端时，您将不再看到该消息。

希望这可以帮助！

答案2

正如评论中指出的那样，您的问题在于shuf有人在您的 ~/.bashrc 文件中输入的命令。您可以通过打开终端并运行以下命令，轻松地从您提供的配置文件中删除所有有问题的行

grep -v "shuf" ~/.bashrc | tee ~/.bashrc

这应该会删除shuf.bashrc 文件中包含的所有行。
