Shell Programming and Scripting

I'm working on a project that basically unzips three zip files.
When these unzip they create about 70+ directories with subdirectories of year/month with about 3 to 9 pdf files in each directory.


Basically, I'm needing to figure out a way to zip these pdf files up.
for instance the script is in /home/reports/
the zip files are in:
/home/reports/archive/notencrypted/clientname/year/month/(report01.pdf/report02.pdf/report03.pdf)

Right now the script unzips the files, moves the original zip files to another directory for backup and replaces whitespaces with _ and strips dashes in the directory and file names.

I've fiddled around with the zip command a bit and keep encountering issues.

When I zip these files up, the three pdfs should be in one zip file for each client.

I'm new to scripting.
But I'm pretty logical. I'm thinking I should be able to variablize the directories or something and have the script enter each one and zip up the files located within. But I don't want to have to script cd /directory/here/etc... 70+ times.

Any help is appreciated.
If it needs explained in a different manner, please let me know.

I got a solution for this:

ls -1 | xargs -n1 -i zip -r {} {} -i \*.pdf

Thanks anyways...
