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.
rosls: it is the ros file listing command, you can command this to know the existing files in the specified ros package.
$ rosls roscpp_tutorials
