Each night I need to do work on a folder 36 days old from the current date. I have a system that writes files to a daily structure like below. I need to keep 35days worth on the local disk and so each night I need to archive off the 36th day. Here is the kicker... There are approx 2 million files per day, so I cannot efficiently scan the whole 2009 folder and only move files older than 35 days. What I need to do is though a batch script determine the path of the folder that is 36days old and then apply my archive logic. I have scripts to determine but having trouble doing the determination to 36 days old. In a pinch I can use perl if there is not a batch way to do this. --Shawn
Folder structure is like this:
2009\07\01
2009\07\02
2009\07\03
.
.
.
2009\08\01
2009\08\02
2009\08\03
#EDIT: Helen's great answer has me 99% of the way there. My only problem is that the month and day out of the vbs is not padded with a zero which i have to deal with in the folder structure. Does anyone have an easy way to pad in a leading 0 if the day or month is less than 10?
Here is what I am doing so far:
for /F "tokens=1-3 delims=/" %%x in ('cscript //nologo get36thday.vbs') do (
SET YYYY=%%z
SET MM=%%x
SET DD=%%y)
except %MM% ends up being 7 instead of 07
The batch option is pretty wicked you will need to calculate which month it is then based of of that run a while loop counting down the days. I would high recommend perl as it would be a few lines of code
using the DateTime module from CPAN
http://search.cpan.org/dist/DateTime/lib/DateTime.pm
my $dt = DateTime->now->subtract(days => 36);
The batch way to determine the date would be too compilcated; it's much easier to use a script for that. Sorry, no Perl sample but a VBScript one:
WScript.Echo DateAdd("d", Date, -36)
You can call this script from a batch file and read the calculated date like this:
for /f %%d in ('cscript //nologo datediff.vbs') do set dt=%%d
If you came here with google like me:
To fix the leading zero's in the .vbs I add a zero in front and strip the right 2 characters.
"0" & "7" -> "07" and "0" & "14" -> "14"
OldDateCode.vbs:
OldDate = DateAdd("d", Date, -36)
DateCode = Year(OldDate) & Right("0" & Month(OldDate), 2) & Right("0" & Day(OldDate), 2)
WScript.Echo DateCode
I also wanted to keep the 1st folder of the month so I compare the last 2 digits (day) with "01"
VBS code to check for 1st day:
If Right(DateCode, 2)="01" then
WScript.Echo "The 1st:" & vbCrLf & DateCode
Else
WScript.Echo "Not the 1st:" & vbCrLf & DateCode
End If
CheckDate.bat:
#Echo Off
Set Folder=D:
for /f %%d in ('cscript //nologo OldDateCode.vbs') do set OldDateCode=%%d
If "%OldDateCode:~6,7%"=="01" (
Echo "Old Backup: %OldDateCode% 1st of the month: keeping..."
) ELSE (
Echo "Old Backup: %OldDateCode% not the 1st of the month: removing..."
RD /S /Q "%Folder%\%OldDateCode%"
)
pause
Make a folder in D:\ with the datecode of 36 days ago. Play around with the -36 and the datecodes.

I have created a scheduled task in Windows that consists of running a batch script.
The problem is that this task has to be scheduled every 1st day of the month except for weekends.
For example, for the month of May, this task should run on May 02nd.
As I can't do it via the task scheduler, my idea is to schedule the execution task every day and add a condition checking that the execution day is the 1st day of the month excluding weekends.
This script would be of the following form :
if today = firstday
C:/MyExec/popo.exe arg1 arg2
Can you help me to write this script please?
Thank you in advance.
There are loads of standard methods already created for this, so just for me to experiment a bit, here is an untested method (untested meaning I simply ensured there are no syntax errors, but I have not tested all dates scenarios etc:
#echo off
if not exist _mlock break>_mlock
for /f "tokens=1-3*delims=_" %%i in ('PowerShell -Command "& {Get-Date -format "dd_ddd_MM"}"') do (
if %%i lss 5 if /i not "%%j" == "Sat" if /i not "%%j" == "Sun" findstr "m%%k">nul _mlock || (
echo m%%k>"_mlock"
start "" "C:\MyExec\popo.exe" "arg1" "arg2"
)
)
The concept: Use powershell to get a non-locale dependent dd ddd mm (04 Wed 05). I check for the day number, if it is less than 5 (overkill in this scenario) and if the ddd is not Sat or Sun and if the month's lock file does not contain the current month number, it will launch the command. If however the lock file contains the month, it will skip it until the month is updated in the file.
You're welcome to test this, if you are not happy with the temp holding file method, you can also let it add the month as a lock to the batch-file itself instead.
Notes:
This does not cater for public holidays, only weekends as per your request.
The ddd day result is language dependent and will require you to amend Sat and Sun accordingly on non English Operating systems.
This version is language-independent, excepted for optional display, and doesn't require lock files.
I've put comments inside the batch itself, feel free to ask for precisions if needed. I've tested it for March and May 2022, it works and doesn't trigger the command more than one time per month.

The "day of week" formula comes from here: Mathematical curiosities / Find the day of the week with a given date (in French).
I took also Gerhard's trick for obtaining a fixed date format quickly through Powershell. It could also have been done with an embedded VBS script, since this language natively have the Weekday function, but it may have been quite unreadable to add a temporary script generation within the batch itself.
Sorry for this answer but I've no reputation to add a comment below the answer I'm referring to, the one by Wisblade:
https://stackoverflow.com/a/72113645/16641207
And I think it is important to make some additions to his beautiful answer.
I'm answering just to point out that in the wonderful piece of batch posted by Wisblade, to avoid sundays and saturdays too, at line 38 instead of this:
if !d! GEQ 6 (
there should be:
if !d! GEQ 5 (
because numbering in the "array" begins with zero.
I would also underline that this conditional expression should be changed if weekend days are different in the country where the code is used: e.g. in Israel one should check if !d! is NOT 0 and NOT 6 (not a monday nor a sunday, but saturdays are workdays there, too).
Apart from that, I gave a big +1 to his question, works so beautifully.
I used in a scheduled task, combined with the ability of Windows Scheduled Tasks to be scheduled only on first mon/tue/wed/thu/fri of every month, and doing this I'm able to execute my instruction just on first working day of every month.
Simple and effective.
I am trying to create an environment variable for yesterday's date. It MUST be in the format of MM/DD/YYYY.
For code I currently have:
set m=%date:~-7,2%
set /A m -= 1
set DATE_YESTERDAY=%date:~-10,2%/%m%/%date:~-4,4%
echo %DATE_YESTERDAY%
This works great, HOWEVER, when I offset to yesterdays day with -1 instead of "12/03/2019" I get "12/3/2019". Thus, missing the zero/0.
Any ideas to keep format as MM/DD/YYYY?
I have seen many other questions regarding this, however, all come short!
NOTE - I do NOT want powershell or VBS scripts. I know this can be done with simply batch.
What you should do is use a method which is not based upon user/locale/PC settings. Commonly wmic is used for that, but it isn't the fastest method and would still require performing some math.
You could use vbscript embedded directly into your batch-file:
<!-- :
#Echo Off
For /F %%# In ('CScript //NoLogo "%~f0?.wsf"') Do Set "YesterDate=%%#"
Echo(%YesterDate%
Pause
GoTo :EOF
-->
<Job><Script Language="VBScript">
dtmYesterday = DateAdd("d", -1, Now())
strDate = Right("0" & Month(dtmYesterday), 2) _
& "/" & Right("0" & Day(dtmYesterday), 2) _
& "/" & Year(dtmYesterday)
WScript.Echo strDate
</Script></Job>
You could also, if you prefer it, use powershell from your batch-file instead:
#Echo Off
For /F %%# In ('PowerShell -NoP "(Get-Date).AddDays(-1).ToString('MM/dd/yyy')"'
)Do Set "YesterDate=%%#"
Echo(%YesterDate%
Pause
Windows command processor cmd.exe does not have built-in support for date calculations. Other script interpreters installed by default on Windows like VBScript or PowerShell support date calculations and Compo posted solutions using VBScript or PowerShell.
Here is a pure batch file solution to calculate yesterday's date from current date with remarks explaining the code. The lines with remark command rem can be removed for faster processing the batch file by Windows command processor.

Please read my answer on Why does %date% produce a different result in batch file executed as scheduled task? It explains in full details the FOR command line using WMIC to get current date in region independent format.
Here is the code above without comments, empty lines and first IF condition needed only for testing the code. The leap year identification is also optimized for using only third rule which means this code is working only for the years 1901 to 2099 which should be enough.

I was wondering if it's possible to compare a specific date (in the MM/DD/YY format) to the current system date, and get the difference in minutes?
In my past questions, I've been able to grab the dates of processes and folders and create the conversion to minutes, but I'm stumped.
My project uses Batch/CMD and Powershell, so any of those formats would be more than acceptable.
Here's the code that I use for grabbing dates to minutes with processes:
if exist "C:\Windows\Prefetch\JAVAW*.*" (
for /f "usebackq" %%A in (`
powershell -NoP -C "[int]([datetime]::Now - (gci 'C:\Windows\Prefetch\JAVAW*.*' -Force).LastWriteTime).TotalMinutes"
`) do set "AgeMinutes=%%A"
)
if exist "C:\Windows\Prefetch\JAVAW*.*" echo JAVAW.pf was modified %AgeMinutes% minutes ago.
if not exist "C:\Windows\Prefetch\JAVAW*.*" echo Error: file not found.
Is a comparison to the current date (and outputting it into minutes) possible?
I have a series of files that have long filenames. For each filename that contains a hyphen I would like to keep the substring in position 6-8, append the _FM07_FY14.prn to the name and ignore the rest of the original filename. The new extension is now .prn. The two digits 07 stands for the month and 14 is the year. The month and year can be found from the "date created" property. Will appreciate it if you can show me how to automatically capture this mm and yy from the date created. Hardcoding this part is okay too since I can sort files by created dates and put them in separate folders.
For example
aaaaaD07.dfdd-1234.A.b.1233 new filename will be D07_FM01_FY14.prn
bbcbaA30dls-d343.a.123d new filename will be A30_FM01_FY14.prn
cdq0dG12ir3-438d.dfd.txt new filename will be G12_FM01_FY14.prn
This is the .bat file I come up with after reading many posts on here, and I don't know how to extract the mm and yy so I hard code it. I am not familiar with Powershell. I can only handle a .bat or .cmd file and run it at the command prompt. Any and all help will be highly appreciated. Thanks!

You would need to change the setting of sourcedir to suit your circumstances.
The format that I use for date is dd/mm/yyyy If yours is different, then you'll need to change the offset in the !fdate:~m,2! phrases. The value of m is the offset into the date string from the first character (the second parameter is the number of characters to select.)
The required REN commands are merely ECHOed for testing purposes. After you've verified that the commands are correct, change ECHO(REN to REN to actually rename the files.
I have filename that look like this
20120528_Sales_Store_001.pdf
20120529_Sales_Store_001.pdf
etc
I need to extract the date from the filename and then associate it to 2 variables
Month
Week
So for each date in the calendar I need to be able to associate the week number and the month name.
Those are FISCAL calendar week&month so it has nothing to do with the actual calendar.
Example
20120528 would be Week 4 and Month April
20120529 would be Week 5 and Month May
Since the fiscal calendar moves from year to year, I know that I will have to redo it every year but im looking for a way to minimize the work that needs to be done.
So I would like to maybe setup something like
Week4 is from ThisDate to ThisDate and is also in the Month of April
Fiscal April would be from 20120403 to 20120430
and count Week 1-2-3-4 (weeks starting every sunday)
Week5 is from ThisDate to ThisDate and is also in the Month of May
Fiscal May would be from 20120501 to 20120528
It is always, 2 month that has 4 weeks and then the 3rd month have 5 weeks.
etc
Or else, I will have to do it once for every day.. which is going to be looong to do and loooong to update every year.
I will need to use the Month and Week variable for directory classification afterwards and that is why I need it.
