I am trying to learn the switch statement, and I'm missing some basics.
For a collection imported from CSV, I want to determine for each row a date in the past, using Get-Date.AddDays(-n)
$list1 = Import-CSV "c:ArchiveFileList1.csv
The columns used from the collection are:
MOVEUNIT – DAYS, MONTHS, or null
MOVENUM – integer with the number of days or months
I then want to apply AddDays(-n) to find the date in the paste.
(Files older than that will be deleted separate from this piece of code).
switch ($list1)
{
DAYS {(Get-Date).AddDays(-$_.MOVENUM); break}
MONTHS {(Get-Date).AddMonths(-$_.MOVENUM); break}
default {Write-Output "Days or Months not specified."}
}
If this method, once corrected, will work for this idea, I would also like to populate a pre-defined column in the collection with that date returned by Switch.
I know I have many issues currently.
Should the declaration have the collection, or the collection.column?
switch ($list1)
switch ($list1.MOVEUNIT)
How does AddDays refer to the MOVENUM column for the corresponding row reading MOVEUNIT given row?
AddDays(-$_.MOVENUM)
AddDays(-$list1.MOVENUM)
