我需要otput文件

0.020003 3 
0.325978 5 
0.203582 43 
0.509831 103 

每一行重複在原始文件中和錯誤的輸出文件中

Answer 1

我的回答仍然是來自這個問題有效：duplicate

awk '!a[$2]||a[$2]>$1 {a[$2]=$1} END {for (i in a) print a[i],i}' file 
0.325978 5 
0.509831 103 
0.203582 43 
0.020003 3 

而且這個工程：

awk '!a[$2]++' file 
0.020003 3 
0.203582 43 
0.325978 5 
0.509831 103
