I have an directory full of Log´s
My current code is
(Get-ChildItem -Path |Select-string -Pattern -AllMatches).matches.count
That will get me an 8 as output. But i want a list of all Logs with an hit and how many was in them.
Like This: "File2020.09.02 17"
How can i do that?

Answer 1

try something like this:
$files = Get-Childitem -Path 'C:\xyz' -File
$out = foreach ($file in $files){
$content = Get-Content $file
$matchCount = ($content | Select-String -Pattern 'xyz' -AllMatches).matches.count
[PSCustomObject]#{
Filename = $file
Matches = $matchCount
}
}
$out

Since Select-String returns MatchInfo objects with a Filename property, you can use Group-Object to group objects by Filename. Group-Object inherently counts the occurrences of any passed properties.
Select-String -Path $path -Pattern $pattern -AllMatches |
Group-Object -Property FileName | Foreach-Objecet {
"{0} {1}" -f $_.Name,$_.Count
}
Group-Object's Name property contains the value of the grouped properties. Its Count property lists the number of occurrences where those grouped properties match among the piped in objects.
You can use a hash table to track the number of hits in your files.
$tracker = #{}
Select-String -Path $path -Pattern $pattern -AllMatches | Foreach-Object {
if ($tracker.Contains($_.Filename)) {
$tracker[$_.Filename]++
} else {
$tracker[$_.Filename] = 1
}
}
$tracker.GetEnumerator() | Foreach-Object {
"{0} {1}"-f $_.Key,$_.Value
}
