Can the Node-Red Exec node handle shell scripts like EXIFTool metadata for photographs?
Welcome to the forum @sfmaplab
Almost certainly it can do.
You should probably pass the name of the image file as msg.payload.
In the exec node specify the full pathname of the script (which should be executable) and tick "Append msg.payload".
Give it a try and let us know how you get on!
thank you lbudd,
I tried that many different ways and it did not work.
However I found this web page today, which looks promisin:

This is what I got using the exec node
But if there is an exiftool node it's no doubt better than using the CLI script.
Especially nice if it returns the exif data in Json format.
hopefully the exif node will do what the OP requires, but if not you can also use the '-j' option to get the cli tool to return json which may be easier to parse that the simple text output.
Thank you, it is working so far, I will try what you say soon.
