Solution

  • Strings can be concatenated by simply creating a new string and expanding the values of the previous string variables directly within it.

    value="${variable} let's expand some more vars ${other_variable}"

    You must always wrap variable expansions in double quotes, otherwise your string will end at the first encountered whitespace character in the variables, which is a very common mistake.

    Note that there should be no spaces around the = in an assignment.
