igrep - search images for matching metadata
igrep [options] pattern files...
The igrep utility is invoked as follows:
igrep [options] pattern filename...
Where pattern is a POSIX.2 regular expression (just like the Unix/Linux grep(1) command),
and filename (and any following names) specify images or directories that should be
searched. An image file will "match" if any of its metadata contains values contain
substring that are recognized regular expression. The image files may be of any format
recognized by OpenImageIO (i.e., for which ImageInput plugins are available).
$ igrep Jack *.jpg
bar.jpg: Keywords = Carly; Jack
foo.jpg: Keywords = Jack
test7.jpg: ImageDescription = Jack on vacation
For a complete description, see /usr/share/doc/openimageio-doc/openimageio.pdf.gz.
