Vista - Powershell - outer variable

get-childitem -recurse
| where { $_.Extension -eq ".csproj" }
| foreach { Get-Content $_.FullName
| foreach { $_.Length } }

This prints the line size of every line in a csproj (pretty pointless true).
How can I also output a outer variable (so to speak) when I've dived further.
So for example let's say for pointeless reasons I wanted to have it print the
filename too so I would get:

Dog.csproj: 10 Dog.csproj: 50 Dog.csproj: 4 Cat.csproj: 100 Cat.csproj: 440

I figure I want to do something like this but this does not work obviously,
(and yes the example is pointless)

PS C:\Projects>
get-childitem -recurse
| STORE THIS IN $filename | where { $_.Extension -eq ".csproj" }
| foreach { Get-Content $_.FullName
| foreach { $filename ":" $_.Length } }

I played with tee-object and outputvariable but I'm a bit lost. If a
powershell guru could answer it would help, also if you could recommend a
book or resource that explains the language syntax fundamentals rather than
API monkey stuff of COM/WMI/VB etc.. (that seems most of what I came across)
it would be most appreciated. Thanks

Hello Matt,

Ths will output the file name with a collection of line lengths in the Lines
column:

get-childitem -recurse -filter *.csproj | select @{n="FileName";e={$.FullName}},@{n="Lines";e={
$(cat $_.FullName).count}}

FYI

Mmm perhaps Log Parser
data parsing and charting!
Pointless -perhaps not at all,
for after doing little pointless
Log Parser data parsing
one might be ready for much larger
Log Parser data parsing!

$filename = "about_globbing.help.txt"
$title = "Char counts information for`n$filename"

LogParser.exe "SELECT
REPLACE_IF_NULL(STRLEN(Text), 0) AS CharsPerLine,
COUNT(*) AS LineCountsWithEqualCharCounts
INTO testChart.gif
FROM '$pshome\$filename'
GROUP BY CharsPerLine
ORDER BY LineCountsWithEqualCharCounts DESC " `
-i textline -stats off -o chart `
-values on -chartType Area -chartTitle $title

invoke-item testChart.gif

Exit

For more help, ask any PowerShell user or MVP or
any IIS user or MVP (where Log Parser comes from,
notice that there is no need to have IIS installed in
order to use Log Parser within the Windows admin's
automation tool, powershell.exe) or just perhaps:

LogParser.exe -h

Have fun data parsing
and perhaps charting
within powershell.exe!

Not sure if i see it right.

$files = get-childitem -recurse -filter *.csproj
foreach ($file in $files)
{
""
"Filename: {0}" -f $($file.Fullname)
"=" * ($($File.FullName.Length) + 10)
$content = gc $file.FullName
$i = 1
foreach ($line in $content)
{
" {2} Line {0,4}: {1,5} Chars" -f $i, $Line.Length, $($file.Name)
$i++
}
}

You'd need an temp variable for that -as Matthias and BJ already pointed out- but you can also get that data from the Microsoft.PowerShell.Commands.MatchInfo object Select-String returns:

Select-String '^' *.csproj |
% {"$($_.filename) [$($_.lineNumber)] : $($_.line.length)"}

I'd also recommend Bruce Payette's book.
