I've so far figured out how to use find to recursively unzip all the files:
find . -depth -name `*.zip` -exec /usr/bin/unzip -n {} \;
But, I can't figure out how to remove the zip files one at a time after the extraction. Adding rm *.zip in an -a -exec ends up deleting most of the zip files in each directory before they are extracted. Piping through a script containing the rm command (with -i enabled for testing) causes find to not find any *.zips (or at least that's what it complains). There is, of course, whitespace in many of the filenames but at this point syntaxing in a sed command to add _'s is a bit beyond me. Thank for your help!
have you tried:
find . -depth -name '*.zip' -exec /usr/bin/unzip -n {} \; -exec rm {} \;
or
find . -depth -name '*.zip' -exec /usr/bin/unzip -n {} \; -delete
or running a second find after the unzip one
find . -depth -name '*.zip' -exec rm {} \;
