Create a dummy file in all directories that include a .jpg
Hello. My latest project has me with the need for the following script. Basically, any directory that includes a .jpg file needs to also have a ".picture" file created (if it doesn't exist). Here's an example of what I need.

Code:
/mnt/user/Pictures/2011/Hawaii - 2011/.picture
/mnt/user/Pictures/2011/Hawaii - 2011/Hawaii.jpg
/mnt/user/Pictures/2012/Mammoth - family - 2012/Mammoth 001 - 2012.jpg

In this example, I want to recursively scan all directories in /mnt/user/Pictures/, and create the .picture file in any directory that has a .jpg file within it (/mnt/user/Pictures/2011/Hawaii - 2011/, for example, does not include a .jpg file). The only directory that would need the .picture file in this example would be /mnt/user/Pictures/2012/Mammoth - family - 2012/. This .picture file is an empty dummy file, and can created as simply as "echo > .picture".

I don't mind recreating the .picture file in each directory, regardless of if it already exists or not. I thought it might be cleaner to only create it if it's needed, but it's not that big of a deal to recreate it each time regardless.


Any thoughts on the code for this script? I started going down the path of using:
Code:
find /mnt/user/Pictures/ -name \*.jpg -print

... however, I quickly hit a brick wall after that.

Thanks for the help in advance!!

igrep

IGREP(1)                                                      General Commands Manual                                                     IGREP(1)

NAME

       igrep - search images for matching metadata

SYNOPSIS

       igrep [options] pattern files...

DESCRIPTION

       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).

       Example:

       $ 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/libopenimageio-dev/openimageio.pdf.gz.

OPTIONS

       --help Print help message

       -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)

       -a     Search all subimages of each file
