我有一份与以下内容相同的报告:
gold 1 1986 USA Americal Eagle
gold 1 1908 Austria-Hungary Franz Josef 100 Korona
silver 10 1981 USA Ingot
gold 1 1984 Switzerland ingot
gold 1 1979 RSA Krugerrand
gold 0.5 1981 RSA Krugerrand
gold 0.1 1986 PRC Panda
silver 1 1986 USA Liberty dollar
gold 0.25 1986 USA Liberty 5-collar piece
silver 0.5 1986 USA Liberty 50-cent piece
silver 1 1987 USA Constitution dollar
gold 0.25 1987 USA Constitution 5-dollar piece
gold 1 1988 Canada Maple Leaf
我想提取如下报告:
Gold pieces: 9
Weight of gold pieces: 6.10
Value of gold pieces: 9729.50
这是我制作的代码:
BEGIN{}
$1 ~/^gold$/
{
goldWeight += $2
++goldCounter
}
END{
printf "Gold Pieces:\t\t%d\n" , goldCounter
printf "Weight of gold pieces:\t\t%1.2f\n" , goldWeight
printf "Value of gold pieces:\t\t%1.2f\n" , goldWeight*1771.00
}
该代码不起作用。我的问题在哪里?
