1 awk 'BEGIN {FS=":"} {print $2}' awkdata
2 awk 'BEGIN {FS=":"} {if($1~/Dan/) print $2}' awkdata
3 awk 'BEGIN {FS=":"} {if($1~/Susan/) print $1,$2}' awkdata
4 awk '{if($1~/^D/) print $1}' awkdata
5 awk '{if($1~/^[C,E]/) print $1}' awkdata       
6 awk 'length($1)=="4" {print $1}' awkdata
7 awk 'BEGIN{FS=":"} {OFS=""} {print $2," ",$1}' awkdata |  awk '{if($1~/\[916/) print $3}'
8 awk 'BEGIN{FS=":"} {OFS="$"} {if($1~/Mike/) print "",$3,$4,$5}' awkdata
9 awk 'BEGIN{FS=":"} {OFS=""} {print $2," ",$1}' awkdata | awk '{print $4","$3}'
10
#!/bin/awk -f
BEGIN {FS=":"}
{if($1~/Savage/) print $1,$2}
{if($1~/Chet/) print $3,$4,$5}
{if($3~/250/) print $1}

第9题是显示姓，后面的例子怎么是显示名在前呢？题目本身有问题
第10题很奇观，排列的顺序太乱了。。。

KornLee
