Please help me writing a shell programming using if else, all possibile code using [[ ]], [ ], (( )).
I tried but it does not work (you can check my previous question Arithmetic binary operators -gt, -lt give error but work in a shell script).

Here is the C version:

int i = 10, n = 20;

if (i < n)
    printf("i smaller");
else if (i > n)
    printf("n smaller");
else
    printf("same");

I wrote this simple script it works too but shows an error

clear
echo Enter 1st number
read n1
echo Enter 2nd number
read n2
echo MUlti is `expr $n1 \* $n2`;
if [$n1 -lt $n2]
then
 echo $n1 'is bigger than' $n2
else
 echo $n2 'is bigger than' $n1
fi

output

Enter 1st number
5
Enter 2nd number
10
MUlti is 50
./script.sh: line 7: [5: command not found
10 is bigger than 5
