Output on the basis of folder and file name - windows

Question

I have some directories structure like below, where the last folder name will be the current date changing everyday, as below:
D:\data\Backup\WINDOWSDATA\18-03-2015
D:\data\Backup\LINUXDATA\18-03-2015
D:\data\Backup\UBUNTUDATA\18-03-2015
Under each date folder (18-03-2015) there will be maximum four .dat files having different time stamps in their names, as given below:
BKP_DS_FETCHER_6AM.dat
BKP_DS_FETCHER_10AM.dat
BKP_DS_FETCHER_2PM.dat
BKP_DS_FETCHER_6PM.dat
I am trying to generate following results in an output.txt file on the basis of simple logic that is if .dat file is there for a particular time, there should come Success otherwise Failed in output.txt for example as below:
output.txt:
FOLDER_NAME 6AM 10AM 2PM 6PM
WINDOWSDATA Success Failed Success Success
LINUXDATA Success Success Failed Success
UBUNTUDATA Failed Success Success Success
Please can somebody help me show the way to achieve it (in Batch or Powershell) ?

Answer 1

Push-Location D:\data\Backup
$todayDir = Get-Item (get-date -Format 'dd-MM-yyyy') -ErrorAction SilentlyContinue
if($todayDir)
{
Push-Location $todayDir
$logResult = #{}
dir -Directory | foreach {
$logResult.($_.Name) = $_.Name | Get-ChildItem -Filter '*.dat' |
foreach {
$isMatch = $_.Name -match 'BKP_DS_FETCHER_(?<hour>.*).dat$'
if($isMatch) {
$Matches.hour
}
}
}
$hourProperties = ($logResult.Values | foreach {$_}) | Sort-Object | Get-Unique
$logResult.Keys | foreach {
$obj = New-Object pscustomobject
$obj | Add-Member -MemberType NoteProperty -Name 'FOLDER_NAME' -Value $_
foreach($p in $hourProperties) {
$v=$null
if($logResult[$_] -contains $p) {
$v = 'Success'
}
else {
$v = 'Failed'
}
$obj | Add-Member -MemberType NoteProperty -Name $p -Value $v
}
$obj
} | Format-Table
Pop-Location
}
Pop-Location

Answer 2

Here is a way to do it in PowerShell:
$date = Get-Date -Format 'yyyy-MM-dd'
$basePath = 'D:\data\Backup\'
$outputPath = 'D:\data\Backup\output_' + $date + '.txt'
$baseFileName = 'BKP_DS_FETCHER_[HOUR].dat'
$hours = #( '6AM', '10AM', '2PM', '6PM' )
function Check-Folder( $folderName )
{
$resultLine = New-Object -TypeName System.Object
$resultLine | Add-Member -MemberType NoteProperty -Name 'FOLDER_NAME' -Value $folderName
foreach( $h in $script:hours )
{
$path = $script:basePath + $folderName + '\' + $script:date + '\' + $script:baseFileName.Replace('[HOUR]',$h)
#Write-Host $path
if( Test-Path -Path $path )
{
$resultLine | Add-Member -MemberType NoteProperty -Name $h -Value 'Success'
}
else
{
$resultLine | Add-Member -MemberType NoteProperty -Name $h -Value 'Failed'
}
}
return $resultLine
}
$results = #()
$results += Check-Folder 'WINDOWSDATA'
$results += Check-Folder 'LINUXDATA'
$results += Check-Folder 'UBUNTUDATA'
$results | Format-Table -AutoSize | Out-File -FilePath $outputPath
Output will look like this:
FOLDER_NAME 6AM 10AM 2PM 6PM
----------- --- ---- --- ---
WINDOWSDATA Success Failed Success Success
LINUXDATA Failed Failed Failed Failed
UBUNTUDATA Failed Success Failed Failed
