To remove all but a certain tag that has spaces in its name

[jsx97]

To remove all but a certain tag that doesn't have spaces in its name, e.g., foo, I use

Code Select Expand

exiftool -overwrite_original_in_place -all= -tagsfromfile @ -foo input.jpg

But how to remove all but a certain tag that does have spaces in its name, e.g., foo bar? I have tried both

Code Select Expand

exiftool -overwrite_original_in_place -all= -tagsfromfile @ -"foo bar" input.jpg


Code Select Expand

exiftool -overwrite_original_in_place -all= -tagsfromfile @ "-foo bar" input.jpg

but neither seems to work.

No tag has spaces in its name.  Please read FAQ #2/3

When you run exiftool, by default it prints descriptions, not tag names
...
Note that descriptions often contain spaces between words, but tag names never do.

From what the FAQ says, it seems entries in the left column, such as, for example, XMP Toolkit are tag descriptions, not the tags themselves, correct?

But then another question: how to detect which tag corresponds to a certain description?

But then another question: how to detect which tag corresponds to a certain description?

You have not used the command in either FAQ #2 or #3. Both of those include the -s (-short) option, not the -sort option.

Many thanks, StarGeek. My bad, a silly typo.
