# Portable:
find . -name '*.pdf' -exec rm {} +

# Faster, if you use GNU findutils:
find -name '*.pdf' -delete

# Or, if you use bash:
# one-time setup - add this in your ~/.bashrc
shopt -s globstar

rm *.pdf **/*.pdf

Sorry, but this would add bloat to rm, when the find utility already
exists for this purpose.  And even if we added it to GNU rm, it wouldn't
help you on any other Unix-like system where such a new option is not
present.  The philosophy of doing one thing well, and using the right
tool for the job, is rather important.

find may look daunting, but learning it will pay big dividends, as it is
then a very powerful tool in your toolbox.
