Updating hash table values in a 'foreach' loop in PowerShell

Question

I\'m trying to loop through a hash table and set the value of each key to 5 and PowerShell gives an error:

$myHash = @{}
$myHash[\"a\"] = 1
$myHash[\"b\"] =          


        

Answer 1

Use clone:

foreach($key in ($myHash.clone()).keys){
    $myHash[$key] = 5
}

Or in the one-liner:

$myHash = ($myHash.clone()).keys | % {} {$myHash[$_] = 5} {$myHash}
