Structure JPEG

[Phil Harvey]

How it is possible to make removal of all metadata except the comment?

I think it is time you read the documentation.  Look for "--TAG".

Whether could make you an example of work ExifTool with ActivePerl, I will be very grateful? At the same time to remove all superfluous of ExifTool?

"Aside from the script I posted, I have no plans to write another script that only removes metadata."

I to tell the truth, and haven't understood as to remove all data from JPEG, except the comment. Tried so - comment, but hasn't helped.

Try this:

exiftool -all= -tagsfromfile @ -comment FILE

as per the documentation.

Thanks big!

Also it is possible to ask last question
Than differ then

-all= -tagsfromfile @ -exif -xmp

From

-all= -exif:all -xmp:all

Code Select Expand

-all= -tagsfromfile @ -exif -xmp

From

Code Select Expand

-all = -exif:all -xmp:all

Do you mean -all= --exif:all --xmp:all ?

The first command is slower because it extracts the EXIF and XMP from the file then writes it back again, replacing the original EXIF and XMP.  My version of the 2nd command deletes everything except the EXIF and XMP.

Whether correctly I have understood you, it is better to use a command

Code Select Expand

-all= -exif:all -xmp:all

It works faster?

[Phil Harvey]

-all= --exif:all --xmp:all

Yes.
