从bash中的连接变量定义数组

Question

Outside of the code I posted below I defined an array fanrp0[1] and fanrp0[2] I did the same for fans 0 through 3. I'm trying to make fstat change and echo each of the fans in two arrays.

    for (( f=1; f<=2; f++ ))
     do
       for (( f2=0; f2<=3; f2++ ))
        do
          fstat="${(fanrp$f2)[$f]}"
          echo $fstat
        done
     done

Answer 1

If fanrp0 , fanrp1 , fanrp2 , and fanrp3 are all arrays, you can write your loops as

for (( f=1; f<=2; f++ ))
do
  for (( f2=0; f2<=3; f2++ ))
  do
    x="fanrp$f2[$f]"
    fstat="${!x}"
    echo $fstat
  done
done

Since f2 is used only to generate the array names, a slightly cleaner syntax would be

for f in {1..2}; do
  for arr in fanrp{0..3}; do
    x="$arr[$f]"
    fstat=${!x}
    echo $fstat
  done
done
