powershell - How might I update this code to run a second time but only on a zip archive already unzipped? -

here code using:

# don't include "\" @ end of $newsource - stop script # matching first-level subfolders $ignore = "somename" $files = gci $newsource -recurse | {     $_.extension -match "zip||prd" -and $_.fullname -notlike $ignore } foreach ($file in $files) {     $newsource = $file.fullname     # join-path standard powershell cmdlet     $destination = join-path (split-path -parent $file.fullname) $file.basename     write-host -fore green $destination     $destination = "-o" + $destination     # start-process needs path exe , arguments passed     # separately. can add -wait have process complete before     # moving next     start-process -filepath "c:\program files\7-zip\7z.exe" -argumentlist "x -y $newsource $destination" -wait } 

however, once finished need go through new directories , unzip .prd files created after unzipping .zip archives. need here tries aren't working , unzip , overwrite unzipped .prd , .zip files.

i already told you $_.extension -match "zip||prd" matches all extensions, because of empty string between 2 | characters in regular expression (all strings contain empty string).

also, -notlike , -like operators behave -ne , -eq operators when comparing value pattern doesn't have wildcards in it, second condition match files full name isn't exactly "somename".

change this:

$ignore = "somename" $files = gci $newsource -recurse | {     $_.extension -match "zip||prd" -and $_.fullname -notlike $ignore }

into this:

$ignore = "*somename*" $files = gci $newsource -recurse | {     $_.extension -match "zip|prd" -and $_.fullname -notlike $ignore }

and code should expect.

as alternative build list of paths want ignore

$ignore = 'c:\path\to\first.zip',           'c:\other\path\to\second.zip',           'c:\some\file.prd',           ... 

and use -notin (powershell v3 or newer) or -notcontains operator exclude files:

$_.fullname -notin $ignore $ignore -notcontains $_.fullname 

---

as side note, i'd use call operator , splatting instead of start-process invoking 7zip.exe:

$destination = join-path (split-path -parent $file.fullname) $file.basename $params      = 'x', '-y', $newsource, "-o$destination" & "${env:programfiles}\7-zip\7z.exe" @params 

---

to extract .prd files extracted zip archives add step loop.

foreach ($file in $files) {     ...     & "${env:programfiles}\7-zip\7z.exe" @params     get-childitem $destination | where-object {         $_.extension -eq 'prd'     } | foreach-object {         # extract matching file here, procedure         # same files in outer loop     } } 

you may want wrap code building destination path , extracting file in function reads paths from pipeline , calls recursively if destination path contains .prd files.

function invoke-unzip {     [cmdletbinding()]     param(         [parameter(             mandatory=$true,             valuefrompipeline=$true,             valuefrompipelinebypropertyname=$true         )]         [validatescript({test-path -literalpath $_})]         [string]$fullname     )      $newsource = $fullname     ...     & "${env:programfiles}\7-zip\7z.exe" @params     get-childitem $destination |         where-object { $_.extension -eq 'prd' } |         invoke-unzip }
