Is it possible to get the Exif tag type with Exiftool?

[k.satou]

I am currently trying to get Exif tag information for my images with Exiftool.
The information I want to get is the type of tag, e.g. Short, Rational, etc.
Is it possible to get this information with Exiftool?

I know that I can get the tag name and value as follows

ksatou@50077PC:/mnt/f/test$ exiftool -s -exif:* images/JPEG/photoshop.jpg
ImageDescription                : Description
Orientation                     : Horizontal (normal)
XResolution                     : 72
YResolution                     : 72
ResolutionUnit                  : inches
Software                        : Adobe Photoshop CS5 Windows
ModifyDate                      : 2021:03:19 16:19:32
Artist                          : Artist
Copyright                       : Copyright
ColorSpace                      : sRGB
ExifImageWidth                  : 200
ExifImageHeight                 : 200
Compression                     : JPEG (old-style)
ThumbnailOffset                 : 382
ThumbnailLength                 : 5103
ThumbnailImage                  : (Binary data 5103 bytes, use -b option to extract)

I also know that Exiv2(https://exiv2.org/) can retrieve the type.

Maybe there is a better way but :

exiftool -v2 images/JPEG/photoshop.jpg

will give you the tag types (and a lot more)

Thanks, greybeard
I was able to get the tag type with the command you gave me.
But is it possible to get the tag and type information in a simpler output like Exiv2?(I use Exiftool because Exiv2 has unsupported extensions)
I would like to get the tag name, value and type obtained by Exiftool and finally processed by a linux command. As follows.

ksatou@50077PC:/mnt/f/test$ exiftool -s -exif:* images/JPEG/photoshop.jpg | cut --delimiter ":" -f 1
ImageDescription               
Orientation                     
XResolution                     
YResolution                     
ResolutionUnit                 
Software                       
ModifyDate                     
Artist                         
Copyright                       
ColorSpace                     
ExifImageWidth                 
ExifImageHeight                 
Compression                     
ThumbnailOffset                 
ThumbnailLength                 
ThumbnailImage

I think that the results output with the v2 option is a bit difficult to process with the linux command.
Thanks.

The information I want to get is the type of tag, e.g. Short, Rational, etc.
Is it possible to get this information with Exiftool?

Not when listing the output from a file without using the -v (-verbose) option as greybeard posted.

The information is available from the -listX option. The output is in XML and by default the list is quite large, especially since it will list all language descriptions.   This can be narrowed down by specifying a group and the -lang option.  Add the -s (-short) option also makes it a bit more human readable.

For example:

Code Select Expand

C:\>exiftool -listx -XMP-DC:all -lang en -s
<?xml version='1.0' encoding='UTF-8'?>
<!-- Generated by Image::ExifTool 12.42 -->

Thanks StarGeek!
Using the -listx option seems to do what I wanted to do.

I appreciate all your help, thank you.
