Idea create -ext value that selects all images

(1/1)

berliner_ffm:
it would be nice, if the -ext-Option would have a way to select all supported image types in one go, like -ext ImgType
With this there would be no need to check beforehand if other files are in a folder besides the images (e.g. sidecars) or to manually list all images types that may be relevant.

Phil Harvey:
I don't understand.  This is the default if you don't specify -ext.  Isn't it?  Are you reading or writing?

berliner_ffm:
Maybe I am doing something wrong.
Just a simple example

exiftool -createdate .


Will select images as well as Excel-Files, xmp-files, but also files that don't have a createdata will be listet.
This is an example output:

--- End code ---
It would be nice that with just one setting only image file (no other documents, no sidecars) would be selected.

Phil Harvey:
ExifTool supports reading many different file types.  Use this command to see them:

exiftool -listf

There is no way to select just image files without specifying a -ext option for each of them.  But what you call an image file may not be the same as someone else (eg. is PDF an image?).

- Phil

Edit: I just thought of one possible solution:  Add this to the command:

-if "$mimetype =~ /image/"

this won't be as fast as using -ext, but it may have the effect you are looking for.
