       The igrep utility is invoked as follows:

       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).

       Example:

       $ igrep Jack *.jpg
       bar.jpg: Keywords = Carly; Jack
       foo.jpg: Keywords = Jack
       test7.jpg: ImageDescription = Jack on vacation

       -i     Ignore upper/lower case distinctions

       -v     Invert match (select non-matching files)

       -E     Pattern is an extended regular expression

       -f     Match against file name as well as metadata

       -l     List the matching files (no detail)

       -r     Recurse into directories

       -d     Print directories (when recursive)
