PowerShell to Search Hash Table Values with -notlike or -notmatch - powershell

Question

I'm attempting to search a hash table for keys that have values that are -notlike or -notmatch 'Snagit'. I am able find an exact match with -notcontains.
Data Example:
Name Value
Host1 FireFox,Snagit 7,Chrome
Host2 Internet,Chrome
Host3 Snagit 5,Internet,Stuff
Code Example:
$global:Csv = Import-Csv -LiteralPath $global:ConvertedSNWReport
$global:hash = #{}
Import-Csv -LiteralPath $global:ConvertedSNWReport | ForEach-Object {
$global:hash[$_.'Computer name'] += #($_.Application)
}
$global:Results = $hash.GetEnumerator() | Where-Object {
$_.Value -notmatch '*Snagit*'
}

Answer 1

You can nest your Where-Object statements to accomplish this:
$results = $hash.GetEnumerator() |Where-Object {
-not($_.Value |Where-Object {$_ -like '*snagit*'})
}
If any of the items in the individual value array matches snagit, the expression will evaluate to $false and the hashtable entrt will be skipped. Conversely, if no items match snagit, it will evaluate to $true
As Ansgar just reminded me, the nested Where-Object statement isn't actually necessary when evaluating strings, since -like doubles as a filter operator on collections:
$results = $hash.GetEnumerator() |Where-Object {
-not($_.Value -like '*snagit*')
}
