算第几周有下面几个参数， 我先用 %V来算。 你可以自己调整

1.        %U     week number of year, with Sunday as first day of week (00..53)
   
2. 
   
3.        %V     ISO week number, with Monday as first day of week (01..53)
   
4. 
   
5.        %W     week number of year, with Monday as first day of week (00..53)
   

复制代码

1. while read a b c d ; do   mon=${b:0:2};   day=${b:2};   week=$(date -d "$mon/$day" +%V);   echo $a $week $c $d; done < infile |awk '{a[$1 FS $2]++}END{for (i in a) if (a[i]>1) print  i,a[i]}' |sort -k2n
   
2. 
   
3. id4 29 2
   
4. id1 30 2
