Find all photos where OffsetTime matches certain value

[newbie24]

Hi,

I would like to find a way to find all photos where OffsetTime does not equal +01:00. I tried with:

Code Select Expand

exiftool -filename -OffsetTime -if "$OffsetTime ne '+01:00'" -r -T .
exiftool -filename -OffsetTime -if "$OffsetTime ne +01:00" -r -T .
exiftool -filename -OffsetTime -if "$OffsetTime ne '1'" -r -T .
exiftool -filename -OffsetTime -if "$OffsetTime ne 1" -r -T .

But none of these find the photos with different OffsetTimes. What am I missing?

I apologize if the question has already been asked, but I did not find the answer on the forum.

The first one should work on Windows - the following works on a Mac:

Code Select Expand

exiftool -filename -offsettime -if '$OffsetTime ne "+01:00"' -r -T .

I am on Windows, using PowerShell. None of the commands work. I've run these for you to see (this is just my testing environment):

Code Select Expand

PS F:\Photos> exiftool -filename -offsettime -T .
file1.jpg       +01:00
file2.jpg       +01:00
file3.jpg       +02:00
file4.jpg       +02:00
file5.jpg       +02:00
file6.jpg       +02:00
PS F:\Photos> exiftool -filename -OffsetTime -if "$OffsetTime ne '+01:00'" -r -T .
PS F:\Photos>

Is there something obvious I'm missing? It just seems so easy...

Maybe try this and see if there are duplicates:

Code Select Expand

exiftool -a -G1 -filename -offsettime .
although it should still work - I'm out of ideas - as you say it does just seem easy but I don't use Powershell - perhaps try it in a normal command window

Tried it in cmd and... it works. This is really weird. At least now we know PowerShell was the problem.

Thanks for the help!

This is really weird. At least now we know PowerShell was the problem.

You have to pay attention to the highlighting in Powershell. And sometimes even that isn't enough as shown in that post. PS's quoting rules are different from every other command line.

Which is why I always recommend you use CMD instead of PS.
