So I am trying to get the date 3 months back using the Powershell command Get-Date. However, when I try to add multiple get-dates in one line it errors out or doesn't give me the results I'm looking for.
The End result I'm trying to get is $checkDate = 6-7-2016
I've tried this, but it doesn't really work:
$checkDate = (Get-Date).month -3 "-" (Get-Date).day "-" (Get-Date).year
Any ideas on how to accomplish this? I'm newer to Powershell and not exactly sure how to concatenate properly.
I'm using PS 4.0
What you are trying to do is format a calculated date. So let's start with calculating the date:
(Get-Date).AddMonths(-3)
That gets you today's date minus 3 months. Next you want to format it in a specific manner. That being Month-Day-Year. That can be done as such:
(Get-Date).AddMonths(-3).ToString("M-d-yyyy")
That results in:
6-7-2016

I'm trying to write a script that will copy a file to a second location, when the file changes.
For that I'm using an if statement like this:
if (
(Get-ChildItem C:\folder2\file).LastWriteTimeUtc -ge (Get-ChildItem C:\folder1\file).LastWriteTimeUtc
)
{exit}
else
{#execute}
Right now the files are exactly the same and if I run
(Get-ChildItem C:\folder2\file).LastWriteTimeUtc
the result for both is
Friday, 15. April 2022 23:32:09
My issue is that both LastWriteTimes appear to be the same and the script shouldn't do anything, but it does. And the reason for that is, that even though both values seem to be the same they are not and comparing them with "-eq" returns "False".
I'm using PowerShell 5.1
Thanks for all the replies. I'm sorry if I wasn't as specific as I should have been. But because of them I found an answer that should work for me.
First I get both dates as ticks and convert them to strings
$datef2 = (Get-ChildItem C:\folder2\file).LastWriteTimeUtc.Ticks.ToString()
$datef1 = (Get-ChildItem C:\folder1\file).LastWriteTimeUtc.Ticks.ToString()
then I replace the last 7 digits with 0 (which is everything small than a second) and compare them
($datef2.Substring(0,$datecb.Length-7) + "0000000") -ge ($datef1.Substring(0,$datenx.Length-7) + "0000000")
Might not be the most elegant solution but it gives the if statement the correct values.
So in my Powershell script I am writing I need to code in a date that is 5 days in the past. I have this but I know it wont work with my formatting method I am using. I just need to figure out how to format it and make it 5 days prior for automation.
$StartTime = (Get-date).AddDays(-5)
$EndTime = Get-date -format "yyyy-MM-ddTHH:mm:ss.fffZ"
The end time has the formatting I want. But I cant apply the formatting to the start time after I perform the AddDays operation.
Thanks for any help. I've been racking my brain over this and I am sure I am just missing something simple.
$StartTime = (get-date).AddDays(-5).ToString("yyyy-MM-ddTHH:mm:ss.fffZ")
I'm looking for a bit of assistance here. I currently have a Powershell script which adjusts the dates within a file. I'm looking to stop myself having to manually adjust these dates every time. What I need is to replace the date two days ago, with the date from yesterday.
I believe that I'd have to use (Get-Date).AddDays(-1) and (Get-Date).AddDays(-2) but I'm not exactly sure how I'd script this in!
What I currently have:
echo "Adjusting Import Dates"
(Get-Content D:\Temp\Example.txt).replace('20180917', '20180918') | Set-Content D:\Temp\Example.txt
You could try this:
$yesterday = (Get-Date).AddDays(-1).tostring("yyyyMMdd")
$twodaysago = (Get-Date).AddDays(-2).tostring("yyyyMMdd")
(Get-Content D:\Temp\Example.txt).replace($twodaysago, $yesterday) | Set-Content D:\Temp\Example.txt
You just introduce variables for the two dates and format them to the required date format.
There is probably some other way of replacing in files, but the above should work.
We have a batch file that runs an end-of-month process. Right now it's a manual process, but we'd like to automate it based on when EOM falls. If the last work day of the month is a Friday (or other weekday), we run the script on Friday night or Saturday. If it falls on a Saturday or Sunday, the script is run on Monday following the weekend. There may be a few exceptions, but that's the general idea.
We're having trouble figuring out how to automate this based on date. Any options will be considered. Powershell, batch, etc...
Any help would be greatly appreciated.
Edit - The dates it selects to run can be a bit random. If we could have it read in a text file with a list of dates to run that would work too.
So we could have a list of dates like:
04-30-2015,
05-31-2015,
06-29-2015,
Then a script could be run that says if today is equal to any of these dates, run the batch file.
The logic isn't completely clear to me, but as said in the comment above, you could run a PowerShell script using Windows Task Scheduler every day (or only Friday/Monday?) and have that script check if the time is right to do something.
From what I can tell it either has to run on Friday or Monday.
You can get the current date in PowerShell with the Get-Date command.
If you pass this through Get-Member you can see all the methods you have on the date object to figure out if the time is right to do something.
get-date | get-member
You'll probably need some methods or properties like this to implement the check:
$today = get-date
$today.DayOfWeek # prints e.g. "Monday"
$today.DayOfWeek -eq 1 # Returns True on Monday
$today.AddDays(1) # Next day, the number can be negative or positive
$today.Day # Returns 6 right now (april 6th)
There are plenty of resources that discuss calling a PowerShell script in Task Scheduler. If what you currently do is run a batch then configure your task to run at 5:00pm every day checking the date against all the dates in your text file.
$milestones = Get-Content c:\temp\dates.txt
$today = Get-Date -Format "MM-dd-yyyy"
If($milestones -contains $today){
# Do stuff and things.
# cmd.exe /K C:\Path\To\Batch.bat
}
If there was a line in the text file "c:\temp\dates.txt" for "04-06-2015" that would satisfy the If condition. Then you could uncomment the line with cmd and update as required.
If you have issues with these concepts it is expected that you do a little research before you ask. If you are still stuck after that please either edit your question of ask a new question.
I just started working with Powershell and I am trying to manipulate a date such that I add two months to the date and set it as a var. Powershell handles this nicely and even handles year rollover. However I am stuck trying to figure out how to also control the format of the date before, during or after adding two months to the date. Both of the statements below give me what I want but i have not been able to figure out how to combine them.
$ndate = (Get-Date).AddMonths(2)
$exp = date -format MM/dd/yyyy
Thank you,
Get-Date (Get-Date).AddMonths(2) -f MM/dd/yyyy
When the -Format operator is not avaiable you can use the ToString method:
(Get-Date).AddMonths(2).ToString('MM/dd/yyyy')
