Write-​Verbose

Writes text to the verbose message stream.

Syntax

Write-Verbose
     [-Message] <String>
     [<CommonParameters>]

Description

The Write-Verbose cmdlet writes text to the verbose message stream in Windows PowerShell. Typically, the verbose message stream is used to deliver information about command processing that is used for debugging a command.

By default, the verbose message stream is not displayed, but you can display it by changing the value of the $VerbosePreference variable or using the Verbose common parameter in any command.

Examples

Example 1: Write a status message

PS C:\> Write-Verbose -Message "Searching the Application Event Log."
PS C:\> Write-Verbose -Message "Searching the Application Event Log." -Verbose

These commands use the Write-Verbose cmdlet to display a status message. By default, the message is not displayed.

The second command uses the Verbose common parameter, which displays any verbose messages, regardless of the value of the $VerbosePreference variable.

Example 2: Set $VerbosePreference and write a status message

PS C:\> $VerbosePreference = "Continue"
PS C:\> Write-Verbose "Copying file $filename"

These commands use the Write-Verbose cmdlet to display a status message. By default, the message is not displayed.

The first command assigns a value of Continue to the $VerbosePreference preference variable. The default value, SilentlyContinue, suppresses verbose messages. The second command writes a verbose message.

Notes

  • Verbose messages are returned only when the command uses the Verbose common parameter. For more information, see about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216).
  • In Windows PowerShell background jobs and remote commands, the $VerbosePreference variable in the job session and remote session determine whether the verbose message is displayed by default. For more information about the $VerbosePreference variable, see about_Preference_Variables (http://go.microsoft.com/fwlink/?LinkID=113248).
