New-TemporaryFile

Creates a temporary file.

Syntax

New-TemporaryFile
   [-WhatIf]
   [-Confirm]
   [<CommonParameters>]

Description

This cmdlet creates temporary files that you can use in scripts.

The New-TemporaryFile cmdlet creates an empty file that has the .tmp file name extension. This cmdlet names the file tmp<NNNN>.tmp, where <NNNN> is a random hexadecimal number. The cmdlet creates the file in your TEMP folder.

This cmdlet uses the Path.GetTempPath() method to find your TEMP folder. This method checks for the existence of environment variables in the following order and uses the first path found:

  • On Windows platforms:

    1. The path specified by the TMP environment variable.
    2. The path specified by the TEMP environment variable.
    3. The path specified by the USERPROFILE environment variable.
    4. The Windows directory.
  • On non-Windows platforms: Uses the path specified by the TMPDIR environment variable.

Examples
