Vista - redirection operators as syntactic suger

Bruce Payette has written

myScript > file.txt
is just syntactic sugar for
myScript | out-file -path file.txt

What would be the equivalent PowerShell statements for the other
output redirection operators?
2>
2>&1

Hi Larry,

Those are implemented in PowerShell as is.

See:

Get-Help about_redirection

Or the rather better help file from 2.0:

Yeah, as Chris said, all of those are built-in to PowerShell and work
just as expected. I've been wracking my brain trying to think of a
out-file equivalent for the others ....

1) myScript > file.txt
myScript | Out-File file.txt
2) myScript >> file.txt
myScript | Out-File file.txt -Append


Sadly, although they implemented the 2> and 2>& operators, and ADDED
"warning" and "verbose" and "debug" output pipes .... they didn't add
any redirection operators for the new pipes, nor did they add anything
beyond those 2> and 2>& for controlling the output of those...

Until PowerShell 2.0

In 2.0, if you have CmdletBinding you can use variable redirection for
the Warning and Error pipes, but not Verbose or Debug.

-WarningVariable $outWarning
-ErrorVariable $outError

So basically, if myScript.ps1 had a first line:
[CmdletBinding()]

You could do all sorts of variations on this:

myScript -OutVariable +output -ErrorVariable +output
Out-File file.txt -InputObject $output
