上面这个数据库的记录内容包括姓名、电话号码和最近3个月的竞选捐款数额。
.打印在第二个月捐款超过100美元的人的姓和名。
awk -F: '$4>100{print $1}' lab3.data
.打印在最后一个月捐款少于85美元的人的姓名和电话号码
awk -F: '$5<85{print $1,$2}' lab3.data
.打印第一个月捐款额在75~150美元之间的人。
awk -F: '$5>=75 && $5<=150 {print $1}' lab3.data
.打印这3个月的捐款总额不超过800美元的人。
awk -F: '$3+$4+$5 <= 800 {print $1}' lab3.data
.打印月均捐款额大于200美元的人的姓名和电话号码。
awk -F: '$3+$4+$5 > 600{print $1,$2}' lab3.data
.打印不在916区的人的姓。
awk -F"[ :]" '$3 !~ "916"{print $2}' lab3.data
.打印每条记录，并在记录前加上其记录号。
awk '{print NR,$0}' lab3.data
.打印每个人的姓名和捐款总额。
awk -F: '{print $1,$3+$4+$5}' lab3.data
.把Chet第二个月的捐款额加上10
awk -F: '/Chet/{$4=$4+10} {print $0}' lab3.data
.把 Nancy McNeil的名字改成Louise McInnes
awk -F: '/Nancy McNeil/{$1="Louise Mclnnes"} {print}' lab3.data

11.写出一个awk脚本输出以下信息
