PowerShell pass a switch to a function with Invoke-Command -
i'm having difficulties passing switch -cleanfolders function using invoke-command. found this, don't know how implement it's not targeted function.
calling function works fine:
delete-oldfiles $target $olderthandays $server -cleanfolders invoke-command -computername "$server" -authentication credssp -credential $credentials -scriptblock ${function:delete-oldfiles} -argumentlist ($target, $olderthandays, $server) but doesn't work @ all:
invoke-command -computername "$server" -authentication credssp -credential $credentials -scriptblock ${function:delete-oldfiles} -argumentlist ($target, $olderthandays, $server, -cleanfolders) full script:

try this:
$sb = { function delete-oldfiles { #... } delete-oldfiles $args[0] $args[1] $args[2] -cleanfolders:$args[3] } invoke-command -computername $server -authentication credssp ` -credential $credentials -scriptblock $sb ` -argumentlist ($target, $olderthandays, $server, $true)
