How to output only the value of the tag? #3

Closed Nexxkinn closed 4 years ago

Nexxkinn commented 4 years ago

I was writing a script to organise downloaded pictures and camera picture by reading LensMake tag. Currently, I'm using this command to get the value of the tag

exif IMG_0120.JPG -t 0xa433 2> /dev/null | awk '/Value:/ {print $2}'

Is there any way to get the value of it without usik awk, since it's pretty trivial to only get the value of it by command and I can't see any command parameters required to set it on.

You can basically do that with the -m (--machine-readable) option, but that adds a newline character (which shouldn't matter in your case). I have in my personal to-do list adding a --save-raw command that would write the raw tag data (without the newline) into the --output file but I haven't gotten around to implementing that.

Ah, I see. Exactly what I've been looking for. Thanks.
