How to create several zip folders (function) from my output? - powershell

Question

I am trying to zip all folders I find in my folder called services.
I use Get-Childitem to find these folders and I want to add the function after the pipeline, but it doesn't work out the way I want.
The zip file should have the same name as the folder itself, so I tried to give the name with "$.FullName" and destinationpath is the folder "C:\com\$.Name"
Here is my script :
Get-ChildItem "C:\com\services" | % $_.FullName
$folder = "C:\com\services"
$destinationFilePath = "C:\com"
function create-7zip([String] $folder, [String] $destinationFilePath)
{
[string]$pathToZipExe = "C:\Program Files (x86)\7-Zip\7zG.exe";
[Array]$arguments = "a", "-tzip", "$destinationFilePath", "$folder";
& $pathToZipExe $arguments;
}

Answer 1

First. Declare variables like folder and destination path.
Second. Change your 7zip folderpath as mine is in (Program Files).
#declare variables
$folder = "C:\com\services"
$destPath = "C:\destinationfolder\"
#Define the function
function create-7zip{
param([String] $folder,
[String] $destinationFilePath)
write-host $folder $destinationFilePath
[string]$pathToZipExe = "C:\Program Files\7-Zip\7z.exe";
[Array]$arguments = "a", "-tzip", "$destinationFilePath", "$folder";
& $pathToZipExe $arguments;
}
Get-ChildItem $folder | ? { $_.PSIsContainer} | % {
write-host $_.BaseName $_.Name;
$dest= [System.String]::Concat($destPath,$_.Name,".zip");
(create-7zip $_.FullName $dest)
}
$_.PSIsContainer will find only the folders, constructing destination path variable $dest and then calling the function. I hope this helps.

If I understand you correctly, you want to pipe the output of gci into your Create-7Zip function, and have the function create a zip file named after each directory you're passing in, like this:
gci | ?{ $_.PSIsContainer } | Create-7Zip
To do this you'll need the cmdlet you're writing to support taking values from the pipeline, which you do with a [Parameter] attribute in your list of params().
function Create-7Zip
{
param(
[Parameter(ValueFromPipeline=$True)]
[IO.DirectoryInfo]$Directory #we're accepting directories from the pipeline. Based on the directory we'll get the zip name
);
BEGIN
{
$7Zip = Join-Path $env:ProgramFiles "7-Zip\7z.exe"; #get executable
}
PROCESS
{
$zipName = $("{0}.zip" -f $Directory.Name);
$7zArgs = Write-Output "a" "-tzip" $zipName $directory.FullName; #Q&D way to get an array
&$7Zip $7zArgs
}
}
Usage:
#Powershell 3.0
get-childitem -directory | Create-7Zip
#Powershell 2
get-childitem | ?{ $_.PSIsContainer } | Create-7Zip
You'll see the output of 7zip; you can capture this information by piping it to somewhere else.
