So I am trying to create a bash/executable, and it in I need to know the version number of Ubuntu on the system. All the ways I have found online consist of lsb_release -r, however I cannot output this into a variable.

Is there any way to get the current version of Ubuntu and save as a variable in a shell executable?

Var=$(lsb_release -r)

echo "$Var"

Should do the trick.

For the numeric portion only add this:

NumOnly=$(cut -f2 <<< "$Var")

echo "$NumOnly"

  so yes thank you, it does work, it outputs Release: 18.04. However is there a way to just get the number? I want to be able to use this variable in an if/else function in the script. The purpose of the if/else is to download the correct version of my application for the distro of ubuntu.
