Hi Stacy,

Try reading this post to get started.  Also, there is this unfinished ExifTool for dummies page.

I put this really long string in - exiftool "-alldates<${directory}${filemodifydate;s/.* //}" "-alldates<${directory}${modifydate;s/.* //}" "-alldates<${directory}${createdate;s/.* //}" "-alldates<${directory}${datetimeoriginal;s/.* //}" -r DIR

And it's doing something

This is a couple examples of the way my file is structured if that helps.  I have a bunch of files where I don't know the exact date and substituted the day for "xx".  I seem to be getting errors on those.  Is there a way I can specify the date I want those to be one by one?  Also it only seems to be giving errors on the Modifydate. Not sure if everything else is working

J:\Pictures\1986\12-25-86 - Christmas
J:\Pictures\1994\05-01-94 - Camping trip

Update:  I stopped it from running.  I went to look at a folder and all it seemed to be doing was adding another file on.  The dates weren't changed on anything that it had gone through already.  I added another attachment for you to see.

Try running it on one file with the -v2 option to see some details about what it is doing.

What does that mean?  What is a -v2 option?  I want to change all the dates I believe

I meant this:

exiftool "-alldates<${directory}${filemodifydate;s/.* //}" "-alldates<${directory}${modifydate;s/.* //}" "-alldates<${directory}${createdate;s/.* //}" "-alldates<${directory}${datetimeoriginal;s/.* //}" -r -v2 FILE

Hello.  I'm not a code guy so some guidance is greatly appreciated.  It seems that my concern has been addressed in this thread, but I'm hoping I can get a precise copy and paste command to perform this.

I have installed the ExifTool application on my MAC.

Issue:  Embedded dates are all wrong after copying them from platform to platform.  Thankfully the date in the filename is correct.  The filename format is IMG-20141222-WA0054.jpg 

Required:  Copy the date from filename to the exif info.  I've got 2500+ pictures in one folder on my laptop.

Can someone please provide me with a command I can copy paste on my MAC to execute this?

Again.  Forgive the ignorance.  Just a guy who messed up 2500+ family pics, and trying to get back on the wife's good side.

Jerry

Hi Jerry,

Embedded dates should not change if you are just copying the file across platforms.

However, filesystem dates are likely to change.  To set the file system modification date from the file name, try this:

exiftool "-filemodifydate<filename" DIR

Note that this will also set the time, which will be 00:54 with your example file name.

Thanks Phil.  I'm an idiot clearly.  All the images are in a folder called SD on the harddrive called HDD6.  So the directory should be HDD6/SD right?
I am getting an error.  I've attached a screenshot of the terminal window.

Thanks,

Jerry

Instead of typing the folder name, try dragging and dropping the folder onto the Terminal window.

Hi Dominic,

The metadata in your image is seriously messed up if it has OtherImage tags in the ExifIFD.  See FAQ 20 for how to repair this.

I scanned old photos where the filename structure is YYYY-MM-DD or YYYY-MM, depending on whether I knew the exact day. In order to keep the photos in order by filename, I sometimes added a letter after the month. See examples of the three kinds of ways photos are named:

1983-04 Pre-birthday setup 001.jpg
1983-04 Pre-birthday setup 002.jpg

1983-04b Birthday 001.jpg
1983-04b Birthday 002.jpg

1987-09-15 Baseball game 001.jpg
1987-09-15 Baseball game 002.jpg

QUESTION: Can you recommend a command line to enable me to change the creation day and make it flexible enough that it won't require a "DD" information if I haven't included it. (Or just default the DD to, "01" if nothing is provided.

Thanks.

What do you mean by "change the creation day"?  To set the fileCreateDate from the fileName, you could do this:

exiftool "-filecreatedate<$filename 01 00:00:00" DIR

This would take as much of the date/time from the file name as possible, then add DD HH:MM:SS = "01 00:00:00" if only YY:MM were given, or add HH:MM:SS = "01:00:00" if YY:MM:DD were given.

The image count number is going to mixed in there as well, so that needs to be taken into account or stripped away.

Troubleshooting hints:
* When posting, include your OS, Exiftool version, and type of file you're processing (MP4, JPG, etc).
* Double all percent signs (%) in a Windows batch file.
* If your GPS coords are negative, make sure and set the GpsLatitudeRef and GpsLongitudeRef tags correctly.

Right.  Maybe like this:

exiftool "-filecreatedate<${filename;s/ .*//} 01 00:00:00" DIR
...where DIR is the name of a directory/folder containing the images.  On Mac/Linux, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).
