嵌套AWK数组的替代方案？

Question

file1 is

foo"blahblah#AAA17"blahblah
foo"blahblah#BBB64"blahblah
foo"blahblah#CCC53"blahblah
foo"blahblah#DDD59"blahblah
foo"blahblah#EEE22"blahblah
foo"blahblah#FFF49"blahblah

file2 is tab-separated and is

AAA17   something9197
BBB64   something333
CCC53   something268
DDD59   something5050
EEE22   something4643
FFF49   something2

I want to add some text to each of the lines in file1. The text will include field 2 from file2, as shown below. Using gawk I can get the desired result with nested arrays:

awk -F"\t" 'FNR==NR {arr1[$1]=$2; next} {split($0,arr2,"#|\"")} {print $0": moomoo "arr1[arr2[3]]}' file2 file1
foo"blahblah#AAA17"blahblah: moomoo something9197
foo"blahblah#BBB64"blahblah: moomoo something333
foo"blahblah#CCC53"blahblah: moomoo something268
foo"blahblah#DDD59"blahblah: moomoo something5050
foo"blahblah#EEE22"blahblah: moomoo something4643
foo"blahblah#FFF49"blahblah: moomoo something2

Is there a simple way to do this that does not involve nested arrays?

Note that the two files might have their lines shuffled - not in order as shown here.

Answer 1

All you need is:

$ awk 'NR==FNR{arr[$1]=$2;next} {print $0 ": moomoo", arr[$3]}' file2 FS='[#"]' file1
foo"blahblah#AAA17"blahblah: moomoo something9197
foo"blahblah#BBB64"blahblah: moomoo something333
foo"blahblah#CCC53"blahblah: moomoo something268
foo"blahblah#DDD59"blahblah: moomoo something5050
foo"blahblah#EEE22"blahblah: moomoo something4643
foo"blahblah#FFF49"blahblah: moomoo something2

Your solution looks quite good already, assuming the files aren't too large. "Nested arrays" is not time-penalizing the way "nested loops" are. But there is a another way to do it using the builtin join , although I don't know if I'd call it "simpler":

cat file1|awk -F"#|\"" '{print $3,$0": moomoo"}'|sort >file3
sort file2|join file3 -|cut -d " " -f 2-
