Scripting maintenance jobs

This is super simple in Powershell

a) get-ChildItem <PathToStartSearch> -rec | Where-Object{$_.name -match "tmp"} | foreach{$_.fullnname}
Example: get-ChildItem \\server1\c$ -rec | Where-Object{$_.name -match "tmp"} | foreach{$_.fullnname}

b) get-ChildItem <PathToStartSearch> -rec |Where-Object{(!$_.PSIsContainer) -and ($_.Length -eq 0)} | foreach{$_.fullname}
Example: get-ChildItem \\server1\c$ -rec |Where-Object{(!$_.PSIsContainer) -and ($_.Length -eq 0)} | foreach{$_.fullname}

c) get-ChildItem <PathToStartSearch> -rec |Where-Object{(!$_.PSIsContainer) -and ($_.Length -ge 10mb)} | foreach{$_.fullname}
Example: get-ChildItem \\server1\c$ -rec |Where-Object{(!$_.PSIsContainer) -and ($_.Length -ge 10mb)} | foreach{$_.fullname}

d) $files = @{}
   get-ChildItem c:\test -rec | Where-Object{(!$_.PSIsContainer)} | foreach{if(!($files."$_.Name")){$files."$_.Name" = $_.FullName}else{write-Host $_.FullName}}
Example:
$files = @{}
get-ChildItem c:\ -rec | Where-Object{(!$_.PSIsContainer)} | foreach{if(!($files."$_.Name")){$files."$_.Name" = $_.FullName}else{write-Host $_.FullName}}

If I run these scripts, will they also check mapped network drives on the local machine?
Or do they have to be run from the server?

They run locally, but the can be run against any server or local.

<PathToStartSearch> can be a local path or a UNC. These commands also do recursive checks.. if you do NOT want that... remove -rec

I got them to work by typing them into the PowerShell command line but how can I stick them into a file and run the script with the servername as an argument? I would like to schedule a task every Friday to do a keyword search on server3 to find tmp files..

For example: I could save it in a batch file which captures the output into a file and runs automatically at 6:00pm. Is there a way to save the script in a file and execute by entering "powershell myscript.ps" or executing the script with the least human interaction possible?

Thanks!

sure.... you can even set the script up as a schedule tasked if you wish.

Anyone know how I could launch a script from a C# windows app? I actually think that powershell will work out perfect, but I need a way of controlling the scripts from a program. If I could call the script from a menu that would be great.

Thanks!

I have been trying to use these scripts on another pc and I downloaded powershell. Windows goes through the motions of installing but says that it can't install until all other versions of powershell are taken off. In Add/Remove programs, powershell is not listed.  How can I fix this issue so that I can run my powershell scripts?
