ExifTool Forum

I would like to add the camera temperature as a keyword tag in the form of:

Temperature/25 C

I use the command:

exiftool -addTagsFromFile @ "-keywords<CameraTemperature" *.jpg

which simply adds the temperature as a tag, how can I append the string: "Temperature/" ?

Try this:

exiftool "-keywords<Temperature/$CameraTemperature" -ext jpg .

But note that on Mac or Linux you must use single quotes instead of double quotes around the keywords argument due to the dollar sign.

Thanks Phil,

Still, that command erases any existing tag. I would like to add the tag with the temp reading to the list.

No problem.  To add to the existing list, use +<:

exiftool "-keywords+<Temperature/$CameraTemperature" -ext jpg .

Thanks Phil!
