我用这段代码来检查用户的输入（总是数字）是偶数还是奇数，但是脚本总是返回“Even”

read -p "Enter a number: " x
if ((x % 2 == 0));
   then echo "Even"; 
   else echo "Odd"; 
fi

我使用这个测试：

def solution(x)
  puts("Number: #{x}")
  run_shell(args: [x]).strip
end

describe "Solution" do
  it "should print 'Even' for even numbers" do
    [0, 2, 4, 78, 100000, 1545452, -2, -10, -123456]
      .each { |x| expect(solution(x)).to eq('Even') }
  end
  
  it "should print 'Odd' for odd numbers" do
    [1, 3, 5, 77, 100001, 1545455, -1, -3, -9, -12345]
      .each { |x| expect(solution(x)).to eq('Odd') }
  end
end
