     CDS             complement(6865961..6867109)

这里的目标是获取第一个文件第一列的每个数字，并查看该数字是否出现在第二个文件中。如果是，我想打印 file2 中匹配项正上方的行:“/locus_tag”

例如，如果在 file1 中我们有 6864294，并且该数字也出现在 file2 上，那么我想打印:/locus_tag="HCH_06747"

Answer 1

这是一个粗略的示例:

awk '
NR==FNR {                                    # hash file 1 to a
    a[$1]
    next
}
{
    q=$0                                     
    while(match($0,/[0-9]+/)) {              # find all numeric strings
        if((substr($0,RSTART,RLENGTH) in a)) # test if it is in a
            print p                          # and output previous record p
        $0=substr($0,RSTART+RLENGTH)         # remove match from record
        }
    p=q                                      # store current record to p
}' file1 file2

                     /locus_tag="HCH_06747"
