终端在加载时无响应，直到按 CTRL+C 才能输入任何内容

我在 Ubuntu 10.04 中使用终端时遇到问题。当我启动它时，它挂起了，如下所示：

终端

我无法执行任何操作，直到按下Ctrl+ C：

我不记得这是什么时候开始的。可能出了什么问题？看起来每次加载时终端都在加载或处理某些内容。我该如何诊断和解决这个问题？

编辑：

以下是 ~/.bashrc 的内容：

一开始设置 -x 告诉我它会尝试不停地重复此操作：

+++++++++++++++++++ line=' acroread gpdf xpdf'
+++++++++++++++++++ list=("${list[@]}" $line)
+++++++++++++++++++ read line

答案1

您正在.profile从进行获取.bashrc，但.profile已经在获取.bashrc（这是正确的方法），因此您陷入了无限循环。请勿.profile从 进行获取.bashrc。

答案2

查看~/.bash_profile或~/.bashrc查找可能“卡住”的程序（或者，更可能的是，等待您输入某些内容；小心grep缺少文件参数之类的情况）。如有必要，您可以set -x在任一程序的顶部添加，以便 shell 在运行它之前向您显示它正在运行的内容。

答案3

您最近是否编辑过您的.bashrc（或类似的文件）？其中的内容将在提示出现之前执行。您可以通过按 Ctrl-C 终止正在发生的一切，这表明某些东西正在运行。

我建议在文件浏览器中打开主文件夹，显示隐藏文件（Ctrl-H）并按“修改日期”排序。然后查看较新的文件。如果最近更改了任何文件，其名称类似于.bashxyz或，.bash_xyz那么您可以重命名它们并尝试重新启动终端。启动终端时将生成文件的新版本。如果这样可以解决问题，那么您可以比较新文件和重命名文件以查看更改。

需要留意的其他文件名是.profile和.inputrc。

另一种方法是启动一个终端并（按下 Ctrl-C 后）top在终端中运行。然后启动第二个终端并查看正在运行的内容。
