根据文件夹和文件名输出

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

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

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
