Vista - Process all the files

I have down the general processing of a single file and I can rewrite the
original file.

get-content test.data | foreach{ $_ -replace "cat","dog" } | set-content
test.data

Now I can't wrap my head around the next pipeline jump and do this for all
the files..

gci | % { gc $_ | % {$_ -replace "dog","cat" } | Set-Content $_ }

thats rewritng ontop of itsself!

Can you one-liner these things?

gci | % { $file = $_; gc $file | % {$_ -replace "dog","cat" } | Set-Content
$file }

thing down the line. The first time you use $_ it has a file as its
value. After you use Get-Content, though, each subsequent $_ refers
to an individual line.

dir | %{$filename = $_.Name; gc $_ | %{$_ -replace 'dog', 'cat'} | Set-
Content $filename}

should work, but I haven't tested it. The important thing is to keep
in mind what the $_ means in each case.

In a case like this it might even be more readable just to give up on
the one-liner and do a

foreach ($file in dir) {
gc $file | %{$_ -replace 'dog', 'cat'} | Set-Content $_
}

Readability goes a long way, especially if you ever want to pass your
knowledge along.
