Function New-OutputFile { <# .SYNOPSIS Function intended for preparing a PowerShell object for output files like reports or logs. .DESCRIPTION Function intended for preparing a PowerShell custom object what contains e.g. file name for output/create files like reports or log. The name is prepared based on prefix, middle name part, suffix, date, etc. with verification if provided path exist and is it writable. Returned object contains properties - OutputFilePath - to use it please check examples - as a [System.IO.FileInfo] - ExitCode - ExitCodeDescription Exit codes and descriptions - 0 = "Everything is fine :-)" - 1 = "Provided parent path <PATH> doesn't exist" - 2 = "The result name contains unacceptable chars" - 3 = "Provided patch <PATH> is not writable" - 4 = "The file <PATH>\\<FILE_NAME> already exist - can be overwritten" - 5 = "The file <PATH>\\<FILE_NAME> already exist - can't be overwritten" .PARAMETER ParentPath The folder path what will be used as the parent path for the new created object. When non existing path will be provided the error code will be returned. By default output files are stored in the current path. .PARAMETER OutputFileNamePrefix Prefix used for creating output files name .PARAMETER OutputFileNameMidPart Part of the name which will be used in midle of output file name .PARAMETER OutputFileNameSuffix Part of the name which will be used at the end of output file name .PARAMETER IncludeDateTimePartInOutputFileName Set to TRUE if report file name should contains part based on date and time - format yyyyMMdd-HHmm is used .PARAMETER DateTimePartInOutputFileName Set to date and time which should be used in output file name, by default current date and time is used .PARAMETER DateTimePartFormat Format string used to format date and time in output file name. .PARAMETER OutputFileNameExtension Set to extension which need to be used for output file, by default ".txt" is used .PARAMETER NamePartsSeparator A char used to separate parts in the name, by default "-" is used .PARAMETER BreakIfError Break function execution if parameters provided for output file creation are not correct or destination file path is not writables .EXAMPLE PS \> (Get-Item env:COMPUTERNAME).Value WXDX75 PS \> $FileNeeded = @{ ParentPath = 'C:\USERS\UserName\'; OutputFileNamePrefix = 'Messages'; OutputFileNameMidPart = (Get-Item env:COMPUTERNAME).Value; IncludeDateTimePartInOutputFileName = $true; BreakIfError = $true } PS \> $PerServerReportFileMessages = New-OutputFile @FileNeeded PS \> $PerServerReportFileMessages | Format-List OutputFilePath : C:\users\UserName\Messages-WXDX75-20151021-001205.txt ExitCode : 0 ExitCodeDescription : Everything is fine :-) PS \> New-Item -Path $PerServerReportFileMessages.OutputFilePath -ItemType file Directory: C:\USERS\UserName Mode LastWriteTime Length Name ---- ------------- ------ ---- -a---- 21/10/2015 00:12 0 Messages-WXDX75-20151021-001205.txt The file created on provided parameters. Under preparation the file name is created, provided part of names are used, and availability of name (if the file exist now) is checked. .EXAMPLE $FileNeeded = @{ ParentPath = 'C:\USERS\UserName\'; OutputFileNamePrefix = 'Messages'; OutputFileNameMidPart = 'COMPUTERNAME'; IncludeDateTimePartInOutputFileName = $false; OutputFileNameExtension = "csv"; OutputFileNameSuffix = "failed" } PS \> $PerServerReportFileMessages = New-OutputFile @FileNeeded PS \> $PerServerReportFileMessages.OutputFilePath | Select-Object -Property Name,Extension,Directory | Format-List Name : Messages-COMPUTERNAME-failed.csv Extension : .csv Directory : C:\USERS\UserName PS \> ($PerServerReportFileMessages.OutputFilePath).gettype() IsPublic IsSerial Name BaseType -------- -------- ---- -------- True True FileInfo System.IO.FileSystemInfo PS \> Test-Path ($PerServerReportFileMessages.OutputFilePath) False The funciton return object what contain the property named OutputFilePath what is the object of type System.IO.FileSystemInfo. File is not created. Only the object in the memory is prepared. .OUTPUTS System.Object[] .LINK https://github.com/it-praktyk/New-OutputObject .LINK https://www.linkedin.com/in/sciesinskiwojciech .NOTES AUTHOR: Wojciech Sciesinski, wojciech[at]sciesinski[dot]net KEYWORDS: PowerShell, File, FileSystem CURRENT VERSION - 0.9.9 - 2017-05-16 HISTORY OF VERSIONS https://github.com/it-praktyk/New-OutputObject/VERSIONS.md LICENSE Copyright (c) 2016 Wojciech Sciesinski This function is licensed under The MIT License (MIT) Full license text: https://opensource.org/licenses/MIT #> [cmdletbinding()] [Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSUseShouldProcessForStateChangingFunctions','')] [OutputType([System.Object[]])] param ( [parameter(Mandatory = $false)] [String]$ParentPath = ".", [parameter(Mandatory = $false)] [String]$OutputFileNamePrefix = "Output", [parameter(Mandatory = $false)] [String]$OutputFileNameMidPart = $null, [parameter(Mandatory = $false)] [String]$OutputFileNameSuffix = $null, [parameter(Mandatory = $false)] [Bool]$IncludeDateTimePartInOutputFileName = $true, [parameter(Mandatory = $false)] [Nullable[DateTime]]$DateTimePartInOutputFileName = $null, [Parameter(Mandatory = $false)] [String]$DateTimePartFormat = "yyyyMMdd-HHmmss", [parameter(Mandatory = $false)] [String]$OutputFileNameExtension = ".txt", [parameter(Mandatory = $false)] [alias("Separator")] [String]$NamePartsSeparator = "-", [parameter(Mandatory = $false)] [Switch]$BreakIfError ) $params = @{ ObjectType = 'File' ParentPath = $ParentPath OutputObjectNamePrefix = $OutputFileNamePrefix OutputObjectNameMidPart = $OutputFileNameMidPart OutputObjectNameSuffix = $OutputFileNameSuffix IncludeDateTimePartInOutputObjectName = $IncludeDateTimePartInOutputFileName DateTimePartInOutputObjectName = $DateTimePartInOutputFileName DateTimePartFormat = $DateTimePartFormat OutputFileNameExtension = $OutputFileNameExtension NamePartsSeparator = $NamePartsSeparator BreakIfError = $BreakIfError } $Result = New-OutputObject @params Return $Result } |
