fnumfilt

Fnumfilt is a helpful linux/posix tool for processing lists of images taken by digital cameras. It is specifically designed to work with images stored in the "r.jpg" file format. Often times, it can be tedious to process a large number of images when only a few need to be worked with. However, with fnumfilt, it is easy to filter number ranges from filenames and generate desired lists.

With fnumfilt, users can either print resulting lists or execute a tool, such as convert (ImageMagick), in order to generate thumbnails more efficiently. It's worth noting that fnumfilt is GPL software, which means that it's free to use. However, using it is done at one's own risk.

In terms of recent updates, there have been some changes to the software to enhance its functionality. For instance, the program has been renamed to 'fnumfilt' in order to avoid confusion with another program. Additionally, the -x function has been modified to always print the executed command. Finally, a conflict with -o/-x has been fixed so that -x can now operate independently.

Overall, fnumfilt is an easy-to-use tool for anyone looking to work more efficiently with digital camera images. Its ability to filter number ranges from filenames and generate lists or thumbnails makes it a valuable asset in any photographer's arsenal.
