我有这个我想要理解的遗留 Linux shell 脚本代码。我将不胜感激任何解释:
if [[ -e $fileName]]; then
我很好奇双括号是什么意思?

我收到一条通知说我需要安装更新,然后我点击了是,但从那时起,由于未满足的依赖关系,我在右上角看到了这个停止标志。当我运行时:
sudo apt-get install -f
我得到一堆要删除的包,然后:
The following extra packages will be installed:
collada-dom2.4-sp-dev
The following NEW packages will be installed:
collada-dom2.4-sp-dev
当我单击是时:

任何帮助将不胜感激,谢谢。
我有一个相机应用程序,我试图在 sudo 下运行:但我收到此错误
cannot connect to x server
问题是当我不使用 sudo 时,程序可以正常打开。但是,此应用程序的某些部分仍然需要管理员权限。
由于它是一个 GUI 应用程序,我尝试使用 gksudo 然后它打开一个窗口询问密码,但在输入密码后应用程序返回并且 GUI 没有打开!
我也试过
sudo xhost local:root
并得到:
xhost: unable to open display""
我正在使用 lubuntu 14.04
我正在尝试运行一个程序,但该程序抱怨说error while loading shared libraries: libQt3Support.so.4: cannot open shared object file: no such file or directory
我可以看到其余需要的 Qt 库都在那里,只有这个没有找到。我做了find / -name libQt3Support.so.4
但是这没有返回任何东西......很可能它丢失了。
我试图在我的电脑上安装 14.04(双启动)。
我是 Linux 新手,我真的不想放弃我的 Windows 操作系统。任何建议将不胜感激。我收到此错误消息“未定义根文件系统”
