Hi Vaclav.
Please use parallel@gnu.org for support unless you want to hire me as
consultant.

Sounds good. If you like GNU Parallel:
* Give a demo at your local user group/team/colleagues
* Post the intro videos on Reddit/Diaspora*/forums/blogs/
Identi.ca/Google+/Twitter/Facebook/Linkedin/mailing lists
* Request or write a review for your favourite blog or magazine
* Invite me for your next conference
If you use GNU Parallel for research:
* Please cite GNU Parallel in you publications (use --bibtex)
If GNU Parallel saves you money:
* (Have your company) donate to FSF https://my.fsf.org/donate/

Something like this ought to work:
parallel 'gpg -e -r testing {} && rm {} && mv {}.gpg done_dir/ &&
echo Done {}' ::: file*.testdata
If you prefer a bash function:
process_file() {
echo Processing $1
gpg -e -r testing $1 \
&& rm $1 \
&& mv $1.gpg done_dir/ \
&& echo $1 processed succesfully \
|| echo $1 failed
}
export -f process_file
parallel process_file ::: file*.testdata
