PowerShell read csv file and create files accordingly - powershell

Question

Basically, I have a CSV file with a lot of columns. Let's say it looks like this:
_username, platform_
username1, platformX1
username2, platformY
username3, platformX2
username4, platformX2
..., ...
I would like to write a script that goes through the file and for each platform, it creates a file with the specific username in a different folder, so I would have:
\platformX1\username1.file
\platformY\username2.file
\platformX2\username3.file, username4.file
etc etc...
I know I should use foreach with an if placed somewhere, but powershell is new for me, and I don't really know how to start it.

Answer 1

Here's something similar tweaked to what you want to do.
This created files of a specific size in your directory
$data = get-content "C:\Data\masteFile.csv"
$drcty = "C:\Data"
foreach($line in $data)
{
$a,$b = $line.Split("{,}")
$parent = $drcty+"\"+$a+"\"
$filename = $parent + $b.TRIM() +".txt"
write-host $filename
New-Item -ItemType directory -Path $parent
fsutil file createnew $filename 2000
}

Answer 2

this seems to do what you want. [grin]
# fake reading in a CSV file
# in real life, use Import-CSV
$InStuff = #'
_UserName, Platform_
username1, platformX1
username2, platformY
username3, platformX2
username4, platformX2
'# | ConvertFrom-Csv
$DestDir = $env:TEMP
$Extension = 'txt'
foreach ($IS_Item in $InStuff)
{
$TargetPath = Join-Path -Path $DestDir -ChildPath $IS_Item.Platform_
if (-not (Test-Path -LiteralPath $TargetPath))
{
# "$Null = " will supress unwanted output from New-Item
$Null = New-Item -Path $TargetPath -ItemType Directory
}
$FileName = $IS_Item._UserName, $Extension -join '.'
$FullFileName = Join-Path -Path $TargetPath -ChildPath $FileName
if (-not (Test-Path -LiteralPath $FullFileName))
{
# "$Null = " will supress unwanted output from New-Item
$Null = New-Item -Path $FullFileName -ItemType File
}
}
i think what it does is apparent, but i know i get ahead of where i otta be at times. so, if there are any questions, please feel free to ask ... [grin]

This worked for me.
$ErrorActionPreference = "Stop"
#Path of the CSV file resides
$csvData = Import-Csv -Path "$env:USERPROFILE\Desktop\data.csv"
$DestinationFolder = "C:\Stuffs"
foreach($record in $csvData)
{
$destPlatformFolder = $DestinationFolder + "\" + $record.platform_
if(-not(Test-Path -Path $destPlatformFolder)){
New-Item -Path $destPlatformFolder -ItemType Directory -Force | Out-Null
}
$destinationFile = $destPlatformFolder + "\" + $record._username
New-Item -Path $destinationFile -ItemType File -Force | Out-Null
}
