See: http://perl-begin.org/learn/Perl-perl-but-not-PERL/ Regarding your question - Perl does not support many of the low-level constructs that make C (and C++) attractive to kernel developers. Perl 5 is also much slower than C (see http://groups.yahoo.com/neo/groups/hackers-il/conversations/messages/5130 ; http://groups.yahoo.com/neo/groups/hackers-il/conversations/messages/5133 - a gross 24 times speedup when translating from perl 5 to C ), and consumes much more RAM. Furthermore, some operations in Perl may not have a predictable and bounded time-to-finish, which is often a problem that kernels need to address. The closest thing I know to an operating system in Perl is http://perllinux.sourceforge.net/ , which is a distribution based on the Linux kernel, where the only compiled (and written in C) parts are the Linux kernel, uClibc and perl 5 itself. But the kernel is still written in Perl. > > This semester, I take beginner PERL course and learn power of > procedural language. I automate many daily task with use of it.

One should note that Perl 5 is a multi-paradigm language and aside from procedural programming, also support object-oriented programming, functional programming, and many other programming paradigms. > > Also about LINUX, I talk to much fellow students and professors, and > take a operate system course use FreeBSD and LINUX.

Writing parts of the Linux kernel in Perl (assuming it is possible), will make it slower and consume more RAM. Note that you can still use Perl for https://en.wikipedia.org/wiki/Filesystem_in_Userspace filesystems, USB handlers, and other things that can run in user-land. > > LINUX kernel can perform more good if written in not C and C++ but > Perl?

Perl 6’s implementations are still incomplete and are still quite slow (though it's been getting a lot better). One can play with them, but they should not be used for production. > Can you want to join me this my project? But > to hear your expertise. > > Am excited to learn and begin study project.

A final note - some kernels have been written in C++ - see OSv for example - http://haifux.org/lectures/310/ . On the other hand, Linus Torvalds (the leader of the Linux kernel project) has voiced his sentiments against using C++ and it's quoted here: http://warp.povusers.org/OpenLetters/ResponseToTorvalds.html .
