debugging - Powershell don't pass Verbosity level to called functions -

consider following script:

function a{     [cmdletbinding()]     param()     write-verbose "a verbose"     write-host "a normal" }  function b{     [cmdletbinding()]     param()      write-verbose "b verbose"     write-host "b normal"      }  b -verbose 

if invoke function 'b' verbose parameter switch specified, function 'a' (that called in 'b') called implicit verbose parameter. there way avoid this? (in other words, call 'b' verbose switch , 'a' without it).

if want suppress verbose output a outside function b, can use $psdefaultparametervalues variable, starting powershell v3.

function a{     [cmdletbinding()]     param()     write-verbose "a verbose"     write-host "a normal" }  function b{     [cmdletbinding()]     param()      write-verbose "b verbose"     write-host "b normal"      }  $psdefaultparametervalues['a:verbose'] = $false b -verbose 

for powershell v2, have set verbose $false when call a b function.

function b{     [cmdletbinding()]     param()      write-verbose "b verbose"     write-host "b normal"      -verbose:$false }
