在awk下面，我试图RSTRING根据另一个变量的值$VCF在file. 的值$VCF已被提取，RSTRING当前是所有以 开头的行R_2019。我想要得到的是RSTRING根据$VCF找到的地方设置的。谢谢 ：）。

文件

xxx_0000 19-0004-La-Fi
xxx_0001 19-0005-Last-Firs
xxx_0003 19-0008-LastN-FirstN
xxx_0005 190320-Control
R_2019_00_00_xxxx-000-v5.6_xxxxx

xxx_0007 19-0000-LastName-FirstName
xxx_0009 19-0001-Las-Fir
xxx_0011 190319-Control
R_2019_00_00_xxxx-00-v5.6_xxxxx

如果$VCF=19-0008-LastN-FirstN

想要的 

RSTRING=R_2019_00_00_xxxx-000-v5.6_xxxxx

如果$VCF=19-0008-Las-Fir

想要的 

RSTRING=R_2019_00_00_xxxx-00-v5.6_xxxxx

awk

awk -v ref="$VCF" 'match($0, ref) {print "$RSTRING"}' file
