[solved] how to check if two arrays are equals?

how to compare to arrays to check if each elements of the first are the same of the second?

Code:

 
for ((i=0;i<$LENGTH;i++)) ; do
    for (j=0;j<$LENGTH;j++)) ; do
        if [ ${ARR1[i]} == ${ARR2[j]} ]
            echo "Are the same";
        fi;
    done;
done;

i try this but it doesn't work

if i make this code doesn't work:

Code:

A=${ARR1[@]};
B=${ARR2[@]};
if [ $A == $B ] ; then
    echo "Are the same" ;
fi;

error is :

Code:

./script: line 3: [: too many arguments

why???

I solved with this code:

Code:

A=${ARR1[@]};
B=${ARR2[@]};
if [ "$A" == "$B" ] ; then
    echo "Are the same" ;
fi;
