Vista - Help creating powershell CMNDLET to find all large files and folde

Help creating powershell CMNDLET to find all large files and folders on a
system. Before I begin, I know C++, Java, and batch file programming, but
Powershell is brand new to me.

I have a server that I want to automate the following three items on:

-Find top 20 largest directories
-Find top 20 largest files
-Find all media (MP3, OOG, MPG, ect) that is not supposed to be there.

I know have come up with a couple commands to do this, I am stuck with the
two needs. Here is what I came up with:

#1. [Finds media]

Get-ChildItem C:\ -recurse -include *.mp3,*.wma,*.wmv,*.mov,*.mpg,*.ogg|
Sort-Object length -descending

#2. [Finds all files puts largest first]

Get-ChildItem C:\ -recurse -include | Sort-Object length -descending

So with the given information, here is what I need:

#1. How do I run these two commands and output it to a file? I used to use a
">" in dos to write screen to file, and then use copy t.txt + s.txt to
combine them.

#2. These commands get ALL files but I only want to show the TOP 20 largest.
Is there a way to do this with the sort option? The Get-EventLog (system
-newest 5 | Sort-Object eventid) made it easy and gave us the "newest 5"
method.

#3. I want to email the results to an email alias (jason@cje.com for
expample). I usually use a "start run mailto:jason@cje.com" in my DOS batch
scripts.

HELP! I really want to get this going for work. I love Powershell and it's
robustness but I am still learning it.

Thanks for any help you can provide.

Run each command and "append" output using "out-file" using "-Append"
switch.

Get-ChildItem C:\ -recurse -include
*.mp3,*.wma,*.wmv,*.mov,*.mpg,*.ogg | sort length -descending | out-
file -Append output.txt
Get-ChildItem C:\ -recurse -include | Sort-Object length -descending |
out-file -Append output.txt

You can retrieve top 20 records using "select-object" cmdlet's "-
First" parameter
Get-ChildItem C:\ -recurse -include | Sort-Object length -descending |
select -first 20

PowerShell CX(Community Extension) Project on http://www.CodePlex.com/PowerShellCX
has a cmdlet called "Send-SmtpMail" which you can use to send emails
of the output.


I am sure that others have much better ways to accomplish the above
tasks that others can come up with surely
In the meantime, hope the above can help you to get started a bit.

Thanks so much

There is no way to tell sort that you only want the top 20 items so it will
collect all the items and then sort them. You can probably improve
performance by writing your own filter which only holds 20 items at a time.
