I downloaded all the pictures from an old spanish social network and the Last modified date is the date that I downloaded the file instead of the real date. I would like to order all the pictures by Last modified date to upload to google photos using the correct date.
I know the real date because the image name has the date and time and I would make a script to change de last modified date using the name of the file. I don't care about the time.
Name of the file format: "yyyy-mm-dd hh-mm-ss.jpg"
I'm using windows, but is not a problem to install Unix to execute some bash script, because it may probabbly be easier.
Is there any way to do this?
Thanks in advance
You can use powershell $(Get-Item *Filename*).creationtime=$(Get-Date "mm/dd/yyyy hh:mm am/pm") in a batch file or command prompt to change the creation date of a file. for more information look at this. In your case you could do:
for %%i in (<folder with all the files path>) do (
set name=%%~i
set name=%name:~0,19%
powershell $(Get-Item %%~i).creationtime=$(Get-Date "%name:~5,2%/%name:~8,2%/%name:~0,4% %name:~11,2%:%name:~14,2%")
)
Note: I have not tested this since I do not have the data set for it.
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 am running the following command in a cmd:
Prog.exe -time Components_2016_04_19_11.ss
I want to write a batch file that will be run hourly and i need the date in the command to change accordingly - the date needs to be in the format above, and the last part of the date is the current hour minus 7 hours
So if the time now is 1/1/2016 20:43 the command will look like this
Prog.exe -time Components_2016_01_01_13.ss
i need help creating the appropriate batch file
Thanks
For future reference, questions resembling "Write this for me. Here are my requirements." aren't well-received around here. But this time, just to prevent any more unhelpful answers from being posted, I'll help you out with a solution.
Pure batch is really cumbersome with date math. Compensating for midnight, month changes, leap years, etc. can be a nightmare. It's much easier to use a different language -- one which has a proper Date object that will handle calendar quirks without having to hack around them.
Here's a PowerShell solution to your problem:
Prog.exe -time ("Components_{0}.ss" -f (Get-Date).addHours(-7).toString("yyyy_MM_dd_HH"))
That's it, just a one-liner. If you require a batch script, you can employ the PowerShell helper to perform the date math heavy lifting.
#echo off & setlocal
for /f "delims=" %%I in (
'powershell -noprofile "(Get-Date).addHours(-7).toString('yyyy_MM_dd_HH')"'
) do (
Prog.exe -time Components_%%I.ss
)
goto :EOF
Get-Date
Get-Date | Get-Member
you can use this:
$GBL = 0
do{
Prog.exe
Get-Date
sleep 3600
}
while($GBL -lt 1)
$GBL it's a infinity variable for the loop. inside of the do execute the program and use the sleep for wait 3600 seconds or 1 hour for execute again. Get-Date it's for mark the date and time when the code it's executed.
I don't understand if you need this or something else.
You can modify the line of Prog.exe with the code you need.
If you answer me i can help you.
Have a good day (:
I have a script that needs to connect to an ftp server and download a file that is only created on Sunday and Sunday's yyyy-mm-dd-hh-mm-ss is appended to the file name. I need to find the last Sunday's date (based on today's date, I assume) and convert it to yyyy-mm-dd (I don't care about the time) so I can construct the filename in my ftp script. I have searched a lot of threads on this and other sites, but I'm kind of a novice at batch syntax. I cannot make assumptions about the date format on the machine that will run this script, but it will be in the same timezone as the ftp server and it will be running at least Windows 7. I thought about using the PowerShell solution in HOW to find last SUNDAY DATE through batch but I've read there are issues with PS script portability. Any help is greatly appreciated. Let me know if I need to provide more detail. Thanks!
(Get-Date).AddDays(-(get-date).dayofWeek.value__)
A couple years ago I wrote a batch script to find yesterday's date. I made it able to calculate 'yesterday' based on today's date. It takes into account months ending on the 30th or 31st, and even the next few leap years. The way I wrote it expects the date to be in the format 'Wed 02/24/2016' or 'ddd MM/DD/YYYY', so it may not be useful to you.
As I look at it now, it's probably more complicated than it needs to be and could probably use some cleanup, but it worked for my purposes. You might be able to modify it somehow to make it find last Sunday, instead of yesterday.

Working with date and time using pure batch can be done, but it is not very convenient.
The GetTimestamp.bat utility makes date/time computations and formatting simple within a batch context. It is pure script (hybrid JScript/batch) that runs natively on any Windows machine from XP onward. The previous link points to the most recent version. The utility was first introduced with a number of examples at http://www.dostips.com/forum/viewtopic.php?t=4847.
Full documentation is available from the command line via getTimestamp /?, or getTimestamp /?? for paged output.
With GetTimestamp, the solution can be as simple as:
#echo off
:: Get the current day of the week, with 0=Sunday, 6=Saturday
:: to be used as an offset from today to get the most recent Sunday
call getTimeStamp -f {w} -r offset
:: Use the offset to get the most recent Sunday in YYYY-MM-DD format
call getTimeStamp -od -%offset% -f {iso-dt} -r lastSunday
:: Show the result
echo lastSunday=%lastSunday%
Try the following from a batch file:
for /f "usebackq" %%d in (`powershell -noprofile -command "'{0:yyyy-MM-dd}' -f [DateTime]::Now.AddDays(-1 * [DateTime]::Now.DayOfWeek)"`) do set "lastSunday=%%d"
echo %lastSunday%
:: -> e.g., "2016-02-21", when run on 2016-02-25
To try this directly on the command prompt, replace %%d with %d.
The PowerShell expression at the heart of the command,
[DateTime]::Now.AddDays(-1 * [DateTime]::Now.DayOfWeek),
which calculates the date of the most recent Sunday, was gratefully borrowed from the answer that you link to in your question.
'{0:yyyy-MM-dd}' -f ... applies the desired yyyy-mm-dd formatting to the date.
powershell -noprofile command ... invokes the PowerShell expression and outputs its result to stdout.
for /f "usebackq" %%d in (`...`) do set lastSunday=%%d captures the output from the PowerShell command and assigns it to batch variable lastSunday.
While invoking PowerShell for just one command from a batch file will be slow, being able to calculate the desired date so conveniently probably outweighs performance concerns.
I am generating the date in a format of YYYYMMDD so that i can append it in the filename that the batch program generates.
But in my local system echo %date% returns
echo %date%
Tue 09/08/2015
The date information is returned so i can modify it the way i want
In server, the same does not return date values
echo %date%
/Tu
I dont have date values to modify it to my required format YYYYMMDD
How do I go about this? Is there any Windows date and time setting that i should be looking at?
The date format depends on the regional settings of your machine. You can check them in control panel (run intl.cpl), they seem to be broken.
