如何提取相同的所有行然后输出文本文件
像下面格式的
chr00:1061 chr00 1061 . C T . PASS DP=42;SS=1;SSC=4;GPV=4.6506E-10;SPV=3.462E-1 GT:GQ:DP:RD:AD:FREQ:DP4 0/1:.:19:9:10:52.63%:5,4,8,2 0/1:.:23:8:14:63.64%:4,4,7,7

使用 awk 按行输出，然后拼接在输出。参考下面 demo 脚本，试一下能不能满足要求

#!/bin/bash
filePath1="/home/dxx/demo1.txt"
filePath2="/home/dxx/demo2.txt"
fileNum=`wc -l ${filePath1} | awk '{print $1}'`

i=0
while true
do
    
    demo1Line=`awk 'NR=='"$i"'{print $0}' $filePath1`
    demo2Line=`awk 'NR=='"$i"'{print $0}' $filePath2`

    echo $demo1Line $demo2Line

    i=`expr $i + 1`
    if [ $i -gt $fileNum ]; then
        break
    else
       
        continue
    fi
done
