Rename based on date when file already exists

[magarlick]

Hi guys

I'm using this command to rename JPGs and their matching XMPs to the data taken:

exiftool "-filename<filemodifydate" "-filename<datetimeoriginal" -d "%Y-%m-%d_%H-%M-%S.%%e" *.jpg *.xmp

I'm getting errors because some of the photos have exactly the same time, so it won't rename them. How can I get around this? Increment the times by a few seconds, say?

Many thanks.

Take a look at the %c variable (see the docs for -w option).  This will add a counter number when there's a duplicate name.

So if you change your date option to -d "%Y-%m-%d_%H-%M-%S%%-c.%%e", two files with the same timestamp would end up like this:

Code Select Expand

2018-06-11_11-39-46.jpg
2018-06-11_11-39-46-1.jpg

Excellent, many thanks.

ANd how can I include a string in the new file name, prefixed at the beginning? Such as

France 2018-08-23_12_24_23.jpg

Cheers.

Is this what you mean?:

-d "France %Y-%m-%d_%H-%M-%S%%-c.%%e"
