You probably could, and then use rev to fix the lines back to their
normal form too.
rev | cut -d. -f2- | rev
You can do that with sed(1) too, though:
sed -e 's/\.[^.]*$//'
Both of these should strip the `.xxx' extension of all input lines.
Then, there's Perl, awk, and a few other tools. Practically unlimited
ways of doing the same thing :)
