Find commets in jpg files.

find / -name "*.jpg" -print -exec rdjpgcom '{}' ';'
Finds comments in jpg files, but I can't figure out how to exclude (in output) files without comments.
Sample Output
/usr/share/pixmaps/faces/energy-arc.jpg
/usr/share/pixmaps/faces/cat-eye.jpg
/usr/share/pixmaps/faces/sunset.jpg
/usr/share/pixmaps/faces/puppy.jpg
/usr/share/pixmaps/faces/launch.jpg

What Others Think

How about this: find / -name \*jpg -print0 | xargs -0 -n1 rdjpgcom | sed "/^$/d" the print0 / -0 combo allows files with spaces (not all versions of find/xargs support this). The sed command suppresses empty lines.

philiph: this shows only comment and not path/file:comments. Thanks for trying.

A little more verbose, but this will show just files with comments: find / -name "*.jpg" -print|while read file;do cmt=$(rdjpgcom "$file"); [ "$cmt" != "" ] && echo "$file" "$cmt";done
