推荐答案

您需要读取压缩文件，如下所示:

You need to read them compressed files like this:

awk '{ ... }' <(gzip -dc input1.vcf.gz) <(gzip -dc input2.vcf.gz)

尝试一下:

awk 'FNR==NR { sub(/AA=\.;/,""); array[$1,$2]=$8; next } ($1,$2) in array { print $0 ";" array[$1,$2] }' <(gzip -dc input1.vcf.gz) <(gzip -dc input2.vcf.gz) | gzip > output.vcf.gz
