如果我站在我的主目录中，按ls然后按Tab然后我会得到一个文件列表。但是，如果我尝试这样做，/etc/elasticsearch那么我就不会得到文件列表。
有什么方法可以实现我想要的，或者有什么解释为什么不能完成？

无论我如何尝试，我最终都会使用 nodejs 4.2.6。是笑话吗？

我的项目只有 20% 的测试覆盖率。https://coveralls.io/github/montao/opsh
我想为语法错误添加一个测试。我无法从简单的 oneliner shell 命令接收输出“语法错误”。你能帮我举一些例子吗？
ctrl+y 粘贴文本并不总是有效（虽然它在 emacs 和终端中有效）。有什么东西总是有效的，所以我从另一个程序复制时不必右键单击并在终端中选择粘贴？我认为有一个程序用于例如将文件内容复制到剪贴板然后粘贴它。
我可以从安装位置成功运行/opt/clion-2017.2.1/bin/clion.sh，但如何更新启动器中显示的内容？在启动器中，它仍然链接到旧的 2017.1.1。
我尝试将我的默认 shell 更改为我自己的 shell opsh（The Open Shell），但它不起作用：

$ make OPENSSL=/usr/local/ssl

我该怎么办？
我想编译并执行一个需要外部 dll 的 C# 程序。在 Visual Studio 中，我们只需添加...引用。使用 Ubuntu 16.04 的相应方法是什么？我使用微软的SDK。
由于我遇到了特定标头的构建问题，我计划重新安装标头并重试。我找不到有关重新安装标头的任何信息。仅删除或清除然后重新安装类似于任何其他软件包是否安全？
也就是说，sudo apt-get remove linux-headers-$(uname -r)?

碰巧我必须以非 sudoer 的标准用户身份登录时安装新程序。然后我必须从 GNOME 登录显示以另一个用户身份登录，这有点麻烦。
还有另一种方法吗？
如果我以不在 sudoer 组中的标准用户身份登录，则似乎无法发出sudo命令。我尝试了pkexec一切，但我能做的唯一方法sudo是以 sudo 用户身份登录。

Thank you for your help.
我想知道这个命令是什么时候引入的，它是某个官方 linux 的一部分还是特定于 ubuntu 的？如何在我的命令行历史记录中搜索我以前使用过的命令？
我使用 MS exchange webmail，我有一个网络日历，我的会议就在那里预订。现在我想知道一种方法，当会议（或几分钟前）有重点时，我可以获得弹出提醒。现在，如果我在我的网络邮件/日历的网页上，我只会看到会议的弹出窗口。
我想要类似于桌面松弛的功能，无论我打开哪个窗口，当我收到消息时都会收到弹出提醒。
有没有办法实现我想要的？我尝试了一些插件，包括 thunderbird 31.8.0 和 lightning 3.3.3 以及 exchange provider 插件，然后什么都不可能，我什至无法添加服务器 url。
