[Enhancement] Recursive processing option

[shssoichiro]

I would like to request a recursive (-R) option built into jpegoptim. I believe this would be very beneficial to the usefulness of the application. I do understand that recursive processing can be done using the "find -type f -name "*.jpg" -exec jpegoptim --strip-all {} ;" command. However, this has two issues:

1. Requires advanced Linux terminal knowledge or using Google to find the command
2. Does not work with the --totals option, since essentially it's running jpegoptim separately for each file

As I see it, jpegoptim wants you to use wildcards etc

That is, just pass it: jpegoptim myDirectory/* for all files

or, if you have folder with files AND other folders with other files, just do: jpegoptim myDirectory/** for a recursive wildcard

jpegoptim will skip everything it can't do like pngs and movies 🤷

And it does work with --totals

Unfortunately that doesn't work

$ jpegoptim 2023/**

jpegoptim: skipping directory: 2023/01
jpegoptim: skipping directory: 2023/02
jpegoptim: skipping directory: 2023/03
jpegoptim: skipping directory: 2023/04
jpegoptim: skipping directory: 2023/05
jpegoptim: skipping directory: 2023/06

But does it skip directory AND it's files, or maybe it just told you that it skipped a directory, but actually did the files in it?

Humm, I don't think so. It didn't output any messaging and had a couple gigs of images.

[benzkji]

can confirm that it does indeed skip and not processes anything in nested folders, even when using xy/**.

Why not simply use jpegoptim -s **/*.jp{,e}g? This would, if my shell knowledge is not too bad, to recursively look for every directory under the current one for JPEG images and optimize them.

Edit: Though, this would not work with all shells, as recursive globing is not supported by all.
