Merge-Hashtable [-Main] <hashtable> [-Overrides] <hashtable[]> [-Force] [<CommonParameters>]

ALIASES

This cmdlet has the following aliases, {{Insert list of aliases}}

DESCRIPTION

This function takes a primary hashtable ($Main) and merges it with one or more override hashtables ($Overrides). Overrides are applied in order, with later values replacing earlier ones if the same key exists. If the -Force switch is used, values will be overridden even if they are empty or $null. The resulting hashtable is returned.

EXAMPLES

EXAMPLE 1

$Main = @{ Key1 = 'Value1' Key2 = 'Value2' } $Override1 = @{ Key2 = 'Override2' } $Override2 = @{ Key3 = 'Value3' } $Main | Merge-Hashtable -Overrides $Override1, $Override2

Output:

Name                           Value
----                           -----
Key1                           Value1
Key2                           Override2
Key3                           Value3

Merges $Main with two override hashtables, applying overrides in order.

EXAMPLE 2

$Main = @{ Key1 = 'Value1' Key2 = 'Value2' } $Override = @{ Key2 = '' Key3 = 'Value3' } $Main | Merge-Hashtable -Overrides $Override -Force

Output:

Name                           Value
----                           -----
Key1                           Value1
Key2
Key3                           Value3

Forces overriding even if the value is empty.
