powershell csv 从另一列中减去一列日期值并将结果写入第三列，其中 1 天等于 24 小时

Question

could you please help me with powershell script:

In CSV file I need to subtract column B date from column C and write result in column A in format 1 day = 24 hrs and same date = 12 hrs Sometimes column B can hold future values, in this case column A should contain minus (-)

It should look like this:

    120 11/22/2020  11/27/2020
    96  11/23/2020  11/27/2020
    72  11/24/2020  11/27/2020
    48  11/25/2020  11/27/2020
    24  11/26/2020  11/27/2020
    12  11/27/2020  11/27/2020
   -24  11/28/2020  11/27/2020
   -48  11/29/2020  11/27/2020

UPD

My script have couple additional steps before subtraction. I'm taking raw file, TAB delimited, converting it to csv, comparing it with archived files to eliminate duplicates, removing unwanted "SrvDate" column name and replacing it with "TAT\hh" name and then exporting it to file. So the only thing is missing - date comparison and fill hours in "TAT/hh" Here it is with sample data:

Script:

$in = Import-Csv (Get-ChildItem -Path E:\Test\RI\In\test\In\*.csv).Fullname -Delimiter "`t" | ? "Test Code" -in "Z620","Z630"

$in2 = Import-Csv (Get-ChildItem -Path E:\Test\RI\In\test\Arc\*.csv).Fullname

$pcomp = 'Accession'
$dup = Compare-Object $in $in2 -Property $pcomp -IncludeEqual -ExcludeDifferent -PassThru | Select-Object -ExpandProperty $pcomp
$badhead = $in | Where-Object {$_.$pcomp -notin $dup} | Select-Object *,@{Name='TAT/hh';Expression={$_.'TAT/hh'}} -Exclude 'SrvDate'
$goodhead = $badhead | Select-Object "Accession","TAT/hh","EntryDate","FinalReportDate","Patient First Name","Patient Last Name","DOB","Gender","Race","Ethnicity","Patient Address","Patient City","Patient State","Patient Zip","Patient Phone","Test Code","Test Name","Result","ClientID","Client Name","Phys  ID","Phys  Name"
if ($goodhead) {$goodhead | Where-Object {$_.$pcomp -notin $dup} | Export-Csv "E:\Test\RI\In\test\Out\Client_PtRecords_$((Get-Date).ToString("yyyyMMdd")).csv" -NoTypeInformation}

Sample data:

Accession   SrvDate EntryDate   FinalReportDate Patient First Name  Patient Last Name   DOB Gender  Race    Ethnicity   Patient Address Patient City    Patient State   Patient Zip Patient Phone   Test Code   Test Name   Result  ClientID    Client Name Phys  ID    Phys  Name

UPD

I used Алексей's script and insert it in my, but I've faced problem to combine results from two different calculations.

In my script - I'm getting results with correct headers, searched elements only, exporting only if there are results and without duplicates in $goodhead.

In Алексей's script I'm getting calculations for TurnAround Time in $tat (I've selected calculated column only)

Is there a way to fill in $tat into $goodhead?

Here is my updated code:

$in = Import-Csv (Get-ChildItem -Path E:\Test\RI\In\test\In\*.csv).Fullname -Delimiter "`t" | ? "Test Code" -in "Z620","Z630"

$in2 = Import-Csv (Get-ChildItem -Path E:\Test\RI\In\test\Arc\*.csv).Fullname

$pcomp = 'Accession'
$dup = Compare-Object $in $in2 -Property $pcomp -IncludeEqual -ExcludeDifferent -PassThru | Select-Object -ExpandProperty $pcomp
$badhead = $in | Where-Object {$_.$pcomp -notin $dup} | Select-Object *,@{Name='TAT/hh';Expression={$_.'TAT/hh'}} -Exclude 'SrvDate'
$goodhead = $badhead | Select-Object "Accession","TAT/hh","EntryDate","FinalReportDate","Patient First Name","Patient Last Name","DOB","Gender","Race","Ethnicity","Patient Address","Patient City","Patient State","Patient Zip","Patient Phone","Test Code","Test Name","Result","ClientID","Client Name","Phys ID","Phys Name"

$tatin = $goodhead | Select-Object * | % {
    $EntryDate = [datetime]::parseexact($_.EntryDate, 'yyyy-MM-dd', $null)
    $FinalReportDate = [datetime]::parseexact($_.FinalReportDate, 'yyyy-MM-dd', $null)

    $tatcalc = switch (($FinalReportDate - $EntryDate).TotalDays){
        0 {12}
        default {$_ * 24}
    }
    [PSCustomObject]@{
        'TAT/hh' = $tatcalc
        EntryDate = $EntryDate
        FinalReportDate = $FinalReportDate
    }

}

$tat = $tatin | Select "TAT/hh"

if ($tat) {$tat | Sort-Object "Result" -Descending | Export-Csv "E:\Test\RI\In\test\Out\Client_PtRecords_$((Get-Date).ToString("yyyyMMdd")).csv" -NoTypeInformation}

Thank you!

PS I'm just a beginner with Powershell, trying to learn it on daily tasks.

$in = Import-Csv (Get-ChildItem -Path D:\tmp\alex\Client_PtRecords_20201203.csv).Fullname -Delimiter "`t" | ? "Test Code" -in "Z620","Z630"

$in2 = Import-Csv (Get-ChildItem -Path D:\tmp\alex\arc\Client_PtRecords_20201202.csv).Fullname

$pcomp = 'Accession'
$dup = Compare-Object $in $in2 -Property $pcomp -IncludeEqual -ExcludeDifferent -PassThru | Select-Object -ExpandProperty $pcomp
$badhead = $in | Where-Object {$_.$pcomp -notin $dup} | Select-Object *,@{Name='TAT/hh';Expression={$_.'TAT/hh'}} -Exclude 'SrvDate'
$goodhead = $badhead | Select-Object "Accession", @{name = "TAT/hh"; expression = {switch(([datetime]::parseexact($_.FinalReportDate, 'yyyy-MM-dd', $null)-[datetime]::parseexact($_.EntryDate, 'yyyy-MM-dd', $null)).TotalDays){ 0 {12}; default {$_ * 24}}}},"EntryDate","FinalReportDate","Patient First Name","Patient Last Name","DOB","Gender","Race","Ethnicity","Patient Address","Patient City","Patient State","Patient Zip","Patient Phone","Test Code","Test Name","Result","ClientID","Client Name","Phys ID","Phys Name"

$tatin = $goodhead | Select-Object * 

$tat = $tatin | Select "TAT/hh"

if ($tat) {$tat | Sort-Object "Result" -Descending | Export-Csv "D:\tmp\alex\arc\Client_PtRecords_$((Get-Date).ToString("yyyyMMdd")).csv" -NoTypeInformation}
