Powershell rename using variable - powershell

Hi am not able to rename a file using the below code. Please help me on this
$date = Get-Date -format "yyyyMMdd"
$path='D:\Users\user\Desktop\Working\'
$fn = $path+'xxx_'+$date+'.txt'
$tn = $path+'yyy'+$date+'.dat'
Rename-Item -Path $fn -NewName $tn
Am getting the below error.
Rename-Item : Cannot process argument because the value of argument "path" is not valid. Change the value of the
"path" argument and run the operation again.
At line:1 char:1
+ Rename-Item -Path $fn -NewName $tn
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Rename-Item], PSArgumentException
+ FullyQualifiedErrorId : Argument,Microsoft.PowerShell.Commands.RenameItemCommand

I'd use Join-Path and Test-Path
$date = Get-Date -format "yyyyMMdd"
$path='D:\Users\user\Desktop\Working\'
$fn = Join-Path $path ("xxx_{0}.txt" -f $date)
$tn = Join-Path $path ("yyy_{0}.txt" -f $date)
If ((Test-Path $fn) -and !(Test-Path $tn)){
Rename-Item -Path $fn -NewName $tn
} else {
"{0} exists is {1}, `n{2} not exists is {3}" -f $fn,(Test-Path $fn),$tn,(!(Test-Path $tn))
}
There is no output on a successful rename, on error the output is like:
D:\Users\user\Desktop\Working\xxx_20180606.txt exists is False,
D:\Users\user\Desktop\Working\yyy_20180606.txt not exists is False

Why is my Powershell script suddenly failing with an error? It's been working for months with no changes

The script included below is now suddenly failing because of the following error. I have not made any changes to it and it's been working for months.
Rename-Item : Cannot bind argument to parameter 'Path' because it is null.

$ndate=get-date ((get-date).adddays($fileday)) -Format "yyyyMMdd"
$nyear=get-date ((get-date).adddays($fileday)) -Format "yyyy"

$file = gci ($filename)
Rename-Item $file $newfilename
Set-Location $curdir
$err=cscript "C:\ImportScripts\FedEx Script\FedExScript.vbs"
if ($err -eq 0) {
cscript "C:\ImportScripts\upscleanuptemp.vbs"
Set-Location $unc
mv $newfilename .\$nyear
Set-Location $curdir

}

Set-Location $unc
Rename-Item $newfilename $file
Set-Location $curdir
}
}
else {

Set-Location $curdir
}
Solved.
Needed to adjust $fileday modifying integer because filename was not matching, as noted in my comments.

Append string in file name using powershell

I am trying to append string in the file name.
$cstzone = [System.TimeZoneInfo]::FindSystemTimeZoneById("India Standard Time")
$csttime = [System.TimeZoneInfo]::ConvertTimeFromUtc((Get-Date).ToUniversalTime(), $cstzone)
$d = Get-Date $csttime -f "dd-MM-yyyy"
$t = Get-Date $csttime -f "HH:mm"
Write-Host "Date : " $d
Write-Host "Time : " $t
gci C:\Result.jtl | % { rename-item –Path $_.FullName –Newname ( $_.basename + $t + $_.extension) }
Expected
Result_14:42.jtl
Error
rename-item : Cannot rename the specified target, because it represents a path or device name.

You can't have colons in file names, they are reserved for drive letters. You can use a tostring to get date in different format:
(Get-Date).ToString("hh-mm")

Test-Path - Illegal characters in path when using a variable

I m fairly new to PowerShell and I apologize in advance if this is a dumb question.
I am trying to construct a new destination/filename where I take the old filename and increment its prefix with +1
$destination = Split-Path -Path 'C:\Users\tom\Desktop\test\0_InstalledPrograms.log'
$file = split-path "C:\Users\tom\Desktop\test\0_InstalledPrograms.log" -Leaf
$array = $file -split '_'
$prefix = $array[0] + 1
$suffix = $array[1]
$newFile = $prefix + '_' + $suffix
$newFile = Out-String -InputObject $newFile
$destination = $destination + '\' + $newFile
Test-Path $destination
Test-Path : Illegal characters in path.
At C:\Users\tom\Desktop\incrementFileName.ps1:18 char:1
+ Test-Path $destination
+ ~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (C:\Users\lgranc...dPrograms.log
:String) [Test-Path], ArgumentException
+ FullyQualifiedErrorId : ItemExistsArgumentError,Microsoft.PowerShell.Commands.TestPathCommand
False
This statement:
$newFile = Out-String -InputObject $newFile
adds a new line (CR+LF) to the string, and is completely unnecessary ($newFile is already a string).
Remove that line and it'll work :)
You can do it easily as follows:
$file = "C:\Users\tom\Desktop\test\0_InstalledPrograms.log"
$splittedName = (Split-Path $file -leaf).split('_')
$newFileName = [string]([int]$splittedName[0] + 1) +'_'+ $splittedName[1]
Move-Item -Path $file -Destination (Join-Path (Split-path $file) -ChildPath $newFileName)

Moving files older than into subfolders

I'm trying to move old files into folders based on creation date. The setup is that the script should check a folder for files older than 5 years and then put them in folders sorted by year with subfolders for each month.
$SourceDir = "C:\Test"
$DestinationDir = "C:\Archive\Test\"
$limit = (Get-Date).AddYears(-5)
$files = Get-ChildItem $SourceDir * | Where-Object {
!$_.PSIsContainer -and $_.CreationTime -lt $limit
}
foreach ($file in $files) {
$Directory = $DestinationDir + "" + $file.CreationTime.Date.ToString('yyyy') + "\" + $file.CreationTime.Date.ToString('MM-MMM')
if (!(Test-Path $Directory)) {
New-Item $directory -Type Directory
}
Move-Item $file.FullName $Directory
I get this error
PS C:\Scripts> .\SortIntoMonths5Year.ps1
You cannot call a method on a null-valued expression.

Fixed it myself
$SourceDir = "C:\Test"
$DestinationDir = "C:\Archive\Test\"
$files = get-childitem $SourceDir * | Where-Object {$_.LastWriteTime -lt (Get-Date).AddYears(-5)}
#$files = get-childitem $SourceDir *
foreach ($file in $files)
{
$Directory = $DestinationDir + "" + $file.LastWriteTime.Date.ToString('yyyy') + "\" + $file.LastWriteTime.Date.ToString('MM-MMM')
if (!(Test-Path $Directory))
{
New-Item $directory -type directory
}
Move-Item $file.fullname $Directory
}

Move-Item to correct Destination

The Script:
Creates a list of folders based on the filenames in the scripts root directory, each folder breaks down the name by "Year/Month/Day"
Moves each file to the designated folder
Error Message:
CategoryInfo : ObjectNotFound:
(S:\Data\TECHNOL...59_20180108.txt:String)
[Move-Item], ItemNotFoundException FullyQualifiedErrorId :
PathNotFound,Microsoft.PowerShell.Commands.MoveItemCommand
My Issue
The files will not move to the correct endpath
#Create Directory
Set-StrictMode -Version 2
$rootPath = split-path -parent $MyInvocation.MyCommand.Definition
cd $rootPath
$FileNameArray = Get-ChildItem -Filter "*.txt"
$FileNameArray = $FileNameArray -replace "....$"
$FileNameArray = $FileNameArray -replace "^59_"
Foreach($f in $FileNameArray)
{
$Year = $f -replace "^\d{0}|\d{4}$" #"....$"
$Month = $f -replace "^\d{4}|\d{2}$"
$Month = $Month | sort -Unique
$Day = $f -replace "^\d{6}|\d{0}$"
#Loop 2a
Foreach($m1 in $Month){
#Loop 2a-a
Foreach($d1 in $Day){
Move-Item -Path ($rootPath + '\59_' + $file + '.txt')
-Destination ($rootPath + '\' + $Year + '\' + $m1 + '\' + $d1)
}
}
}
Apologies for the spaghetti code & simple question, I am new to both Computer Science and PowerShell.
The following script has two security features:
The MD command has a trailing -confirm you have to answer
The Move-Item has a -WhatIf which shows what would be done without the Parameter
If the script works OK, remove them both.
## Q:\Test\2018\05\03\SO_50158185.ps1
Set-StrictMode -Version 2
$rootPath = Split-Path -Parent $MyInvocation.MyCommand.Definition
cd $rootPath
Get-ChildItem "59_20[0-9][0-9][0-1][0-9][0-3][0-9].txt" |
Where-Object {$_.BaseName -Match '59_(?<year>\d{4})(?<Month>\d{2})(?<Day>\d{2})'}|
ForEach-Object {
$DestDir = Join-Path $rootPath ("{0}\{1}\{2}" -f $Matches.Year,$Matches.Month,$Matches.Day)
If (!(Test-Path $DestDir)) {MD $DestDir -Confirm| Out-Null}
$_ | Move-Item -Destination $DestDir -WhatIf
}
Figured it out guys! Just needed to change $file to $f. Thanks for all the help.
