[Solved] new to Perl – having trouble with a floating point comparison

by


That code you have isn’t Perl. Here’s what might look more like Perl:

my $vmVersion = `defaults read '/Applications/VMware Fusion.app/Contents/Info' CFBundleShortVersionString`;
if ($vmVersion > 8.4) {
    print "compliant";
} else {
    print "update required";
}

Note two things:

  1. Version numbers are not floating point numbers. You should really use a semantic version library, such as SemVer, for version comparison.
  2. Your messages should probably include newline characters (\n). Without those, when a user runs your program, their prompt will print in a funny location afterwards. 🙂
