11l楼的有错误，试试这个
awk '{if($2!=99)next;getline var;
if(index(var,$1)&&index(var,"147"))print $1}' 111
chr1_217
chr1_5663

your code got the some bug
# it is not a good idea to use getline and index function for this case

$ cat FILE
chr1_217 99
chr1_217 99
chr1_217 147
chr1_217 99
chr1_5663 99
chr1_5663 147
chr1_15663 99
chr1_156633 1477

$ awk '$1==s1&&s2==99&&$2==147{print $1}{s1=$1;s2=$2}' FILE
chr1_217

$ awk '{if($2!=99)next;getline var;
if(index(var,$1)&&index(var,"147"))print $1}' FILE

a[$1]=a[$1]?a[$1]$22
先判断a[$1]是否为真
如果为真，就是相当于执行 a[$1]=a[$1]?a[$1]$2
如果为假，就是相当于执行 a[$1]=$2

Kotokz

1. a[$1]=a[$1]?a[$1]$2:$2

复制代码

if a[$1] != null
then a[$1] = a[$1]$2
else a[$1] = $2
