ubuntu常用指令

1.pwd：顯示當前路徑

2. rm -rf * :刪除當前資料夾內的所有內容

3.make -j3：4個CPU時，最快速度make

4.find / -name “ ×××” ：全盤尋找×××

5.mv aa  bb：將aa更名為bb

6.cp 檔案  待移動位置：複製

複製資料夾：cp  -r  檔案  待移動位置

7.make clean 刪除之前make生成的一些檔案

8.catkin_init_workspace 初始化工作區

9. sudo apt-get check檢查是否有包有異常

10.  /home/david/MySoft/Eigen3/Eigen/src/Core/util/Macros.h 裡面可檢視當前eigen的使用版本。

11.python --version  檢視當前python版本

12.切換python2和python3：

echo alias python=python2 >> ~/.bashrc

source ~/.bashrc  //指定為python2

echo alias python=python3 >> ~/.bashrc

source ~/.bashrc  //指定為python3

13.不同版本的OpenCV間相互切換

不同版本的OpenCV編譯好後，都會生成一個 OpenCVConfig.cmake，這個檔案中指定了對應庫函式和標頭檔案的位置。在本教程的情況下，OpenCV2對應的OpenCVConfig.cmake在/usr/local/opencv2/share/OpenCV，OpenCV3對應的OpenCVConfig.cmake在/usr/local/opencv3/share/OpenCV。因此，如果要使用那個版本的OpenCV只需要將對應版本OpenCVConfig.cmake的路徑寫入CMakeLists.txt即可。這就是說，當自己所寫的程式使用到OpenCV3時，在 FIND_PACKAGE( OpenCV REQUIRED ) 前，新增set(OpenCV_DIR “/usr/local/opencv3/share/OpenCV”) 這樣計算機就找到OpenCV3的對應標頭檔案和庫檔案了，如果使用OpenCV2，那麼新增set(OpenCV_DIR “/usr/local/opencv2/share/OpenCV”)在FIND_PACKAGE( OpenCV REQUIRED ) 前就好。比如下面是一個使用OpenCV3的例子。

CMAKE_MINIMUM_REQUIRED( VERSION 2.8)
PROJECT(useOpenCV)
set(OpenCV_DIR "/usr/local/opencv3/share/OpenCV") 
FIND_PACKAGE(OpenCV REQUIRED)
INCLUDE_DIRECTORIES(${OpenCV_INCLUDE_DIRS})
add_executable(useOpenCV useOpenCV.cpp)
TARGET_LINK_LIBRARIES(useOpenCV ${OpenCV_LIBRARIES})

14.pkg-config --modversion opencv ：檢視opencv版本

15.E: 有未能滿足的依賴關係。請嘗試不指明軟體包的名字來執行“apt-get -f install”(也可以指定一個解決辦法)

直接在終端輸入sudo apt-get --fix-broken install即可解決問題。

16.第二次血的教訓：sudo apt-get autoremove libtiff5-dev 不能隨便用！！！

zp@zp:~/opencv-3.3.1/build$ sudo apt-get autoremove libtiff5-dev

我選了是！！！！

好了重新走一波安裝吧【手動微笑】萬幸的是，這次解除安裝了哪些安裝包還知道，可以一個一個地重新安裝回來。筆芯筆芯。
