You probably want to do something like

my $var = `command`;

Notice that the single quotes were replaces by backticks. There are certain problems with using backticks, but it's usually OK to use them to run a simple and safe command.

Also, your current code will only capture v09.11. If you want to capture v09.11-e020, use this:

my ($exp) = $var =~ m/(v\d{2}\.\d{2}-[a-z]\d{3})/;

    I'm getting the following error:

    Unmatched ( in regex; marked by <-- HERE in m/( <-- HERE v\d{2}\.\d{2}(a-z\d{3})/

      You probably only need one opening bracket in the beginning and one closing in the end:

      m/(v\d{2}\.\d{2}-[a-z]\d{3})/

      Brackets should usually match - for every opening bracket there must be one closing bracket.
