Intersecting text files by its location from a list

问题

I need to intersect the a file from a list of locations as like this

File 1

cat02 2 5
cat02 2 3
cat03 2 3

File2

cat02 1 xxx xxx
cat02 2 xxx sss www
cat02 3 swe ede rrr
cat02 4 aqw ede efd
cat02 5 aws ede as
cat02 6 aqw
cat03 1 aaa
cat03 2 wer
cat03 3 ddddd

expected output

cat02 2 xxx sss www
cat02 3 swe ede rrr
cat02 4 aqw ede efd
cat02 5 aws ede as
cat02 2 xxx sss www
cat02 3 swe ede rrr
cat03 2 wer
cat03 3 ddddd

For this purpose I used this code

awk 'FNR==NR{
start[$1]=$2
till[$1]=$3
next}$2>=start[$1] && $2<=till[$1]' File1 File2

But if I am trying to grep two ranges for cat02 I only get the output for the last range read instead of both ranges:

$ awk 'FNR==NR{
start[$1]=$2
till[$1]=$3
next}$2>=start[$1] && $2<=till[$1]' file1 file2
cat02 2 xxx sss www
cat02 3 swe ede rrr
cat03 2 wer
cat03 3 ddddd

回答1:

$ cat tst.awk
NR==FNR {
    vals[$1,$2] = $0
    next
}
{
    for (i=$2; i<=$3; i++) {
        key = ($1 SUBSEP i)
        if (key in vals) {
            print vals[key]
        }
    }
}

$ awk -f tst.awk File2 File1
cat02 2 xxx sss www
cat02 3 swe ede rrr
cat02 4 aqw ede efd
cat02 5 aws ede as
cat02 2 xxx sss www
cat02 3 swe ede rrr
cat03 2 wer
cat03 3 ddddd

回答2:

$ awk 'NR==FNR {s[$1]=$2;e[$1]=$3;next} 
                $2>=s[$1] && $2<=e[$1]' file1 file2

cat02 2 xxx sss www
cat02 3 swe ede rrr
cat02 4 aqw ede efd
cat02 5 aws ede as
cat03 2 wer
cat03 3 ddddd

actually it's the identical code with yours, perhaps your line endings is a problem. You can see with cat -A file.
