Powershell output formatting? - powershell

Question

I have a script that scans for a specific folder in users AppData folder. If it finds the folder, it then returns the path to a txt file. So we can see the computer name and username where it was found.
I would like to be able to format the what is actually written to the text file, so it removes everything from the path except the Computer and User names.
Script:
foreach($computer in $computers){
$BetterNet = "\\$computer\c$\users\*\AppData\Local\Google\Chrome\User Data\Default\Extensions\gjknjjomckknofjidppipffbpoekiipm"
Get-ChildItem $BetterNet | ForEach-Object {
$count++
$betternetCount++
write-host BetterNet found on: $computer
Add-Content "\\SERVERNAME\PowershellScans\$date\$time\BetterNet.txt" $_`n
write-host
}
}
The text files contain information like this
\\computer-11-1004S10\c$\users\turtle\AppData\Local\Google\Chrome\User Data\Default\Extensions\gjknjjomckknofjidppipffbpoekiipm
\\computer-1004-24S\c$\users\camel\AppData\Local\Google\Chrome\User Data\Default\Extensions\gjknjjomckknofjidppipffbpoekiipm
\\computer-1004-23S\c$\users\rabbit\AppData\Local\Google\Chrome\User Data\Default\Extensions\gjknjjomckknofjidppipffbpoekiipm

Answer 1

If you have each line in a form of the string $string_containing_path then it is easy to split using split method and then add index(1) and (4) that you need:
$afterSplit = $string_containing_path.Split('\')
$stringThatYouNeed = $afterSplit[1] + " " + $afterSplit[4]
You can also use simple script that will fix your current logs:
$path_in = "C:\temp\list.txt"
$path_out= "C:\temp\output.txt"
$reader = [System.IO.File]::OpenText($path_in)
try {
while($true){
$line = $reader.ReadLine()
if ($line -eq $null) { break }
$line_after_split_method = $line.Split('\')
$stringToOutput = $line_after_split_method[1] + " " + $line_after_split_method[4] + "`r`n"
add-content $path_out $stringToOutput
}
add-content $path_out "End"
}
finally {
$reader.Close()
}

If you split your loop into two foreach loops, one for computer and user directory it would be easier to output the name of the user directory.
$output = foreach($computer in $computers){
$UserDirectories = Get-ChildItem "\\$computer\c$\users\" -Directory
foreach ($Directory in $UserDirectories) {
$BetterNet = Get-ChildItem (Join-Path $Directory.fullname "\AppData\Local\Google\Chrome\User Data\Default\Extensions\gjknjjomckknofjidppipffbpoekiipm")
Add-Content "\\SERVERNAME\PowershellScans\$date\$time\BetterNet.txt" "$computer $($Directory.name)`r`n"
write-host BetterNet found on: $computer
$BetterNet
}
}
$output.count
