[switch] $NoInheritance - Powershell Code

Hi All,

I am trying to understand this line of code, what exactly is the [switch] $NoInheritance ? how does it work?

function DoPermissions
{
    param( $permissionGroup, $folder, $level, [switch] $NoInheritance)
}

Open in new window

Thank you in advance

A switch is an optional parameter without (explicit) value (in fact it is a boolean). If left out when calling the function, it is $false, if you call with -NoInheritance it is $true.
You can call it with an explicit value, which you might want to do if the default value differs from $false, by e.g. using -NoInheritance:$false.

ok I kind of get it, if do dopermissions --NoInheritance it will:

switch (noinheritance)
{
Pattern 1 {Statement block}
Pattern 2 {Statement block}
Pattern n {Statement block}
}

is this correct?

No. [switch] and switch are totally different kind of things. $NoInheritance just has the values $false or $true, depending on what has been provided or left out at calling the function.
