Cmdlet of the week

• Write-Verbose
  • Use in parameter section of functions and combine with an If statement to enable or disable verbose logging.

  Function Get-Foo {
  Param ( [switch] $Verbose )
  If ($Verbose) { $VerbosePreference = "Continue" }
  Write-Verbose "My verbose stuff goes here
  Write-Verbose "and is not seen at all unless"
  Write=Verbose "I supply the -verbose switch"
  }

One-Liners

• write-verbose "$(Get-Date -f 's') my log entry goes here"

Gotchas

• Problems occur when a brackets "[" are in your filenames.
  • Stamp ACL onto Directory Tree thread on Powershell Community forum
• Careful with following the $_ automatic variable by a colon
  • Out-Host "This $_:won't work right."
  • Out-Host "This ${_}:will."
