I have installed ROS2 distribution eloquent follow RoS guideline by debian package , but I want to check which version of eloquent has been installed , can anyone help me through this?
You ROS version is ROS2, and your Distro is Eloquent.
If you are looking for a semantic version number (a number like "X.Y.Z"), they are associated to the individual packages that were installed.
When installing ros2 through debian packages, (apt-get install), it installs a bunch of packages onto your computer with each package having their own different version number.
If you are looking to use ROS2, eloquent has reached it's end-of-life, so you should consider either:
As you probably know, there is no roscore in ros2, so I don't know what the alternative would be. If you're looking to find the version for a specific package, and you know the name of that package, you can do something like below:
Eg. Replace rviz2 with the package you're trying to see
ros2 pkg xml rviz2 | grep version
To see all packages on your system, you can use ros2 pkg list
