[ROS 2] 단축 명령어 alias 설정하기

PC 환경을 ROS2에 맞게 변경해보자

export MY_ROS2_WS='ros2_ws'
source ~/ros2_ws/install/local_setup.bash;
alias cw="cd ~/${MY_ROS2_WS}";
alias cs="cd ~/${MY_ROS2_WS}/src";
alias cb="cw && colcon build --symlink-install";
alias cbp="cw && colcon build --symlink-install --packages-select"
