For most shell languages neither of those statements make an array. You cannot have spaces on any side of the = character:

bash array:
Code:
var_1=( "array element 1"  "array element 2")

ksh array:

Code:
set -A var_1 "array element 1"  "array element 2"

The answer to your question is No, there is no single command, you have to program a couple of pipes:

one way assuming you have the arrays already and they are array and array2:
Code:
echo ${array1[*]} | tr -s ' ' '\n' > file1
echo ${array2[*]} | tr -s ' ' '\n' > file2
diff file1 file2

I am assuming you want real differences. If you simply want to know if they are equal:


Code:
if [  "${array1[*]}" = "${array2[*]}"  ] ; then
   echo "same"
else 
  echo "different"
fi

Not sure what you wanted, really.
