Subject: Question about 'unless' (negated if)

Using this snippet:

    dir.each { |str|
        ftp.get(str) unless str.index('d') == 0
        system("mkdir " + lpath + str.split('/').index(str.length-1))
        system("cd " + lpath + str.split('/').index(str.length-1))
        }


Will system be called both times all the time, or will the first one
be called only when the unless condition is satisfied, or will both
calls only be enacted when the unless condition is satisfied?  I've
seen examples that used else statements with unless calls, but I'm not
sure if this is needed here or not.  Unless is new to me :)
