Hello guys,
I've searched for this topic but I couldn't find any method that worked for my case and even though I'm into programming the amount of switches and options in exiftool give me a headache...
The issue that I have is that a have a lot of images saved from Facebook which are named "FB_IMG_<unix timestamp>". I'd like to parse the timestamp into the pictures as exif date and then possibly rename the files in a much better fashion (DD-MM-YYYY_HH:MM:SS). Could you please guide me on how to do that?
You could copy the unix time like this
exiftool -d "%s" "-DateTimeOriginal<${FileName;m/(\d{9,})/;$_=$1}" /path/to/files/
After that, then you could rename by date. See the examples under Renaming Examples (https://exiftool.org/exiftool_pod.html#RENAMING-EXAMPLES) or search on the forum.
Tried it but got :
ParserError:
Line |
1 | exiftool -d "%s" "-DateTimeOriginal<${FileName;m/(\d{9,})/;$_=$1}" ./
| ~
| Use `{ instead of { in variable names.
EDIT: nvm, fixed that issue however it didn't work for my images. no changes were made :/

This isn't anything from exiftool. Test on the command line before trying to call it from anything else.

What is the exact command and exact output from the command line? It works correctly here
C:\ >exiftool -P -overwrite_original -d "%s" "-DateTimeOriginal<${filename;m/(\d{9,})/;$_=$1}" Y:\!temp\bbbb\FB_IMG_M1593184426.jpg
1 image files updated
C:\ >exiftool -DateTimeOriginal -g1 -a -s Y:\!temp\bbbb\FB_IMG_M1593184426.jpg

PS D:\test>
This should work if you are using cmd.exe. But if you are using PowerShell, you should use single quotes I think.

Tried it again in CMD but still didnt work

The thing I have noticed is that my timestamps are a lot longer than the usual ones...but they are correct as I have checked them on the online converter, dates are correct.

None of those are Unix time stamps. The first seven are in Date Month Year Hour Minu Second format. The last two have too many numbers. 1499787692217 translates to 05/18/49496 @ 8:16pm and 1499832546704 translates to 10/19/49497 @ 11:51pm.
For the unix time stamp translation, since I didn't know what time range your files had, I chose 8 or more digits, as that would cover a range from 1973 onward. For the latter two, if the first 10 digits are the time stamp, then change
{8,} into
{8,10}. Or if you know all the time stamps are after 09/09/2001, just use
{10}.
For the first seven, you need a different command.
exiftool "-DateTimeOriginal<${FileName;tr/0-9//cd;s/^(\d\d)(\d\d)(\d{4})/$3$2$1/}" /path/to/files/C:\>exiftool -P -overwrite_original "-DateTimeOriginal<${FileName;tr/0-9//cd;s/^(\d\d)(\d\d)(\d{4})/$3$2$1/}" Y:\!temp\bbbb

6 image files readFor this command, since the separating characters vary, it will strip away any non-numeric characters. Then it will resort the first 8 characters to be in YearMonthDay order.
I cannot agree on the fact that these are not timestamps. Go here : https://www.epochconverter.com/ and enter the value from the 1st timestamp. It gives the correct date, but the whole time is in miliseconds which is the issue here.
Could you be more specific? What is the value you are talking about?

The first 6 files do not have an epoch timestamp. The last 2 files do, and these may be used to set the FileModifyDate like this:
exiftool "-filemodifydate<${filename;/(\d{10})/ and $_ = $1}" -d %s DIR- Phil
I was replying to the previous comment. Let me check the method you invoked. I also want to thank you all for being extremely helpful :)

The devil is in the details. You didn't get the -d %s correct in any of your commands.
Ahhhh yess.....when I tried it with -d it didn't work but I also forgot about %s .....thank you so much!
