.SYNOPSIS
|
|
Demonstrates how to write a command that works with paths that do
|
|
not allow wildards and do not have to exist.
|
|
.DESCRIPTION
|
|
This command does not require a LiteralPath parameter because the
|
|
Path parameter can handle paths that use wildcard characters. That's
|
|
because this command does not "resolve" the supplied path. This command
|
|
also does not verify the path exists because the point of the command is
|
|
to create a new file at the specified path.
|
|
.EXAMPLE
|
|
C:\PS> New-File -Path xyzzy[1].txt -WhatIf
|
|
This example shows how the Path parameter can handle a path that happens
|
|
to use the wildcard chars "[" and "]" and does not exist to start with.
