Compare two array

Hi all,
I have two identical arrays.
$a = 0,1,2,3
$b = 0,1,2,3

I need to know if the arrays is identical

if ($a -eq $b) this is doesn't working

Thanks,
Didi

I believe you can use compare-object.

I have used compare-object successfully.$a = 1,2,3
$b = 1,3,4
$c = compare-object $a $b
$c
write-host "Objects inly exist in the first file"
$c | % { if ($_.SideIndicator -match '<=') {$_.InputObject}}

write-host "Objects inly exist in the second file"
$c | % { if ($_.SideIndicator -match '=>') {$_.InputObject}}


$a = "a","b","c"
$b = "a","c","d","e"
$d = compare-object $a $b
$d

write-host "Objects only exist in the first file"
$d | % { if ($_.SideIndicator -match '<=') {$_.InputObject}}

write-host "Objects only exist in the second file"
$d | % { if ($_.SideIndicator -match '=>') {$_.InputObject}}

FYI, when two arrays are the same, compare-object returns null.
