You're welcome.

Exactly.
Just remove the option -maxdepth 1

*** Important note ***: Actually, the provided command is a combination of two commands (find+zip),
which *does* recursively zip. The recursively part is performed by the zip's option -r.

Assuming following directory structure

Code:

sourcedir/dir 1/sub dir A/sub sub dir B/sub sub sub dir C/
sourcedir/dir 2/sub dir 1/sub sub dir 2/
sourcedir/dir 3/sub-dir-x/sub-sub-dir-y/sub-sub-sub-dir-z/

and the command being run in the sourcedir, it would produce 3 zip files:

Code:

/sourcedir/dir 1.zip # (incl. all sub dirs of dir 1)
/sourcedir/dir 2.zip # (incl. all sub dirs of dir 2)
/sourcedir/dir 3.zip # (incl. all sub dirs of dir 3)

I highly doubt you want to remove the maxdepth option, because it would create a backup of the backup of the backup of the backup...

Hope you get the idea

Edit:
You could add the echo command to just see what would happen, and afterwards remove the -maxdepth 1 part and see the difference.

Code:

find . -maxdepth 1 -type d ! -name ".*" -exec bash -c 'echo zip -r "$0.zip" "$0"' {} \;
