Exiftool: read one tag only

Hi folks-

I’m working on a tagging project which requires reading and adding tags. I’ve figured out how to add a keyword:

exiftool -keywords+='aardvark' /Users/a351958/Desktop/joe.shmoe.jpg

but I’m having trouble reading only the keywords tags (I don’t want to do a full dump of all the tags).

exiftool -p -keywords /Users/a351958/Desktop/joe.shmoe.jpg

does not work…

thanks in advance for any help…


got it.

exiftool -keywords /Users/a351958/Desktop/joe_shmoe.jpg

the -p option is only for redirecting to a print file…
