Hi @evaristobayonagomez,

Glad to hear that you just finished the Python course.

To move to different folders in the shell, use the cd Linux command, and the roscd ROS shortcut. Here some examples below:

user:~$ pwd # show the current directory (folder)
/home/user
user:~$ ls # list the content of a directory
catkin_ws
user:~$ cd catkin_ws/ # change to the specified subdirectory
user:~/catkin_ws$ ls
build  devel  src
user:~/catkin_ws$ cd src
user:~/catkin_ws/src$ ls
CMakeLists.txt  ardrone_action_client.py  services_quiz          test.cpp  topics_quiz      will_this_save_on_timeout
Untitled.txt    my_custom_srv_msg_pkg     sos_service.py         test.py   unit2
actions_quiz    my_package                sos_service_client.py  test2.py  unit_3_services
user:~/catkin_ws/src$ pwd
/home/user/catkin_ws/src
user:~/catkin_ws/src$ cd .. # move one level up in the directory tree
user:~/catkin_ws$ pwd
/home/user/catkin_ws
user:~/catkin_ws$ roscd topics_quiz # change to the folder of an existing package
user:~/catkin_ws/src/topics_quiz$ pwd
/home/user/catkin_ws/src/topics_quiz
user:~/catkin_ws/src/topics_quiz$ ls
CMakeLists.txt  launch  package.xml  src

You can learn more at http://www.learnshell.org/. Also, we are going to release a FREE Linux basics course soon.

I hope this helps. Keep pushsing your ROS learning!
