I have this Fibonacci script

#!/bin/bash
if (test $# -ne 1) then
 echo "Use: 0ドル number"
exit 1 fi
for c in ‘seq 1 1ドル‘
do
 if (($c == 1))
 then
n0=1;
 echo "fibonacci(1)=$n0";
 elif (($c == 2));
 then
n1=1;
 echo "fibonacci(2)=$n1";
 else
 n=$(($n0+$n1));
 echo "fibonacci($c)=$n";
 n0=$n1;
 n1=$n;
fi done
type here

I have to made a substitution of the expression evaluation $(($n0+$n1))with the shell command expr $n0 + $n1.

I Rembember that to assign the output of a command to a varible i have to made command > output.txt but I don’t know how to apply it on this exercise. Thank you so much for your help.
