A Quick Introduction to the Linux Terminal¶
As explained earlier, you'll be working extensively with the Linux Terminal throughout this lab course. An idle WSL-ROS terminal instance will look like this:
Here, the presence of the $
symbol indicates that the terminal is ready to accept a command. Text before the $
symbol has two parts separated by the :
symbol:
- Text to the left of the
:
tells us the name of the Linux user ("student" in this case) followed by the WSL-ROS version that you are working with. - Text to the right of the
:
tells us where in the Linux Filesystem we are currently located (~
means "The Home Directory", which is an alias for the path:/home/student/
).
If you don't see the $
symbol at all, then this means that a process is currently running. To stop any running process enter Ctrl+C
simultaneously on your keyboard.
