Let’s start working with file system of the ROS. You need to have a Linux operating system where ROS is installed and workspace has been made.

You need 3 important commands to access your package and know what the files are in your ros file system.

rospack, roscd, rosls

rospack:it will help finding you your desired package. For example if you look for roscpp pakage your command should be

  $ rospack find roscpp

Which will return the roscpp path in the ros system.

roscd: it can be used to know the current ros path also to change ros directory, the command

  $ roscd

will return you the current ros path. If you want to change the directory to roscpp package you should command

  $ roscd roscpp

Which will give you the path for roscpp.
