4.2 Editing ~/.bashrc to use shortcut command using alias

$ gedit ~/.bashrc

~/.bashrc를 수정하여 단축키를 설정할 수 있다.

use alias alias [shortcut]='[command]' ex) alias sb='source ~/.bashrc'

파일을 수정한 후, terminal을 재시작하거나 $ source ~/.bashrc 명령어를 이용하여 ~/.bashrc 의 수정사항을 적용할 수 있다.

위 이미지대로 수정 후 한번 적용하였다면, 앞으로는 $ source ~/.bashrc 를 $ sb 로 실행할 수 있다

4.3 Terminator

$ sudo apt install terminator -y

Ctrl + Shift + E split vertically

Ctrl + Shift + O split horizontally

Ctrl + Shift + W close window

Alt + Arrow move between window

MS Teams

5. Install ROS Melodic

$ sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
$ sudo apt install curl
$ curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -
$ sudo apt update
$ sudo apt install ros-melodic-desktop-full
$ echo "source /opt/ros/melodic/setup.bash" >> ~/.bashrc
$ source ~/.bashrc
$ sudo apt install python-rosdep python-rosinstall python-rosinstall-generator python-wstool build-essential
$ sudo rosdep init
$ rosdep update

추가적으로 carvis repository 내부의 catkin_ws에 있는 패키지들은 개별적으로 apt나 github를 이용하여 다시 다운받은 후 build하는 것을 추천

6. Install Anaconda & create env

Download anaconda https://www.anaconda.com/products/distribution

$ cd ~/Downloads/
$ sha256sum Anaconda3-2022.05-Linux-x86_64.sh # downloaded file name, tab key will help autofill existing file
$ bash Anaconda3-2022.05-Linux-x86_64.sh
$ source ~/.bashrc
(base)$ conda --version # check version
(base)$ conda search python # check available python version
(base)$ conda create -n vision python=3.7
(base)$ conda activate vision
(vision)$ conda deactivate
(base)$ 

sha256sum is for validating installer file, refer to Anaconda hashes

6.1 Anaconda auto activation setting

$ conda config --set auto_activate_base false # auto activation off

$ conda config --set auto_activate_base true # auto activation on

Terminal을 켰을 때 (base) 환경으로 자동 시작 설정

Terminal을 재시작하면 적용된다

6.2 Difference between conda and default terminal

기본에서 실행하면 python=2.7, python3=3.6, (base)에서는 python=3.9, (vision)에서는 python=3.7을 확인할 수 있다.

7. Python setting
