The tail utility is part of the coreutils on linux.

• Source tarball: ftp://ftp.gnu.org/gnu/coreutils/coreutils-7.4.tar.gz
• Source file: http://git.savannah.gnu.org/cgit/coreutils.git/tree/src/tail.c

I've always found FreeBSD to have far clearer source code than the gnu utilities. So here's tail.c in the FreeBSD project:

• http://svnweb.freebsd.org/csrg/usr.bin/tail/tail.c?view=markup
