我有两个文本文件:
文件 1:
#CHROM POS ID REF ALT
1 61442 rs2531261 A G
1 924629 rs28622096 A G,T
1 974662 rs2465135 G T
1 995481 rs9442393 T G
文件 2
#CHROM POS ID REF ALT FORMAT
1 61442 rs2531261 A G GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
1 924629 rs28622096 A G,T GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
1 974662 rs2465135 G T GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
1 987909 rs34235844 G GTG GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
1 995481 rs9442393 T G GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
我想根据第 3 列 (ID) 合并文件。我的输出文件应如下所示:
输出:
#CHROM POS ID REF ALT FORMAT
1 61442 rs2531261 A G GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
1 924629 rs28622096 A G,T GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
1 974662 rs2465135 G T GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
1 995481 rs9442393 T G GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
我想用awk
。
答案1
看起来你想筛选根据文件 1 中的 ID 查找文件 2(而不是合并文件):
$ awk 'NR==FNR {a[$3] = 1; next} $3 in a' file1 file2
#CHROM POS ID REF ALT FORMAT
1 61442 rs2531261 A G GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
1 924629 rs28622096 A G,T GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
1 974662 rs2465135 G T GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
1 995481 rs9442393 T G GT:GL:GQ:DP:CGA_RDP:EHQ:HQ:CGA_CEGL:PS:CGA_CEHQ:AD
