Wrote a casually, can consult

 #!/bin/bash 
A=0 
B=1 
Fibo=(0, 1) 
Sum=1 
Echo "fibo list 1:" $a 
Echo "fibo list 2:" $b 
For ((I=3; i<=20; i++)); 
Do 
Let a + c=$$b; 
A=$b; 
B=$c; 
Fibo=(${fibo (@)} $c); 
Let d=$I - 1; 
Echo "fibo list" $I ":" ${fibo [$d]}. 
Let the sum=$sum + ${fibo [$d]}. 
The done 
Echo "fibo 20 sum is:" $sum
