Does anybody have a source code for the MORE filter used on Linux, because I am curious as to how it works.

For a small, studyable implementation start by identifying which more binary your system actually uses. As and pointed out, most distributions ship more as a packaged program — the fastest, reliable route is to find the package that provides /bin/more and then fetch that package's source.

Common, distro-agnostic steps:

which more
# Debian/Ubuntu:
dpkg -S $(which more)
# RPM systems:
rpm -qf $(which more)

Once you know the package name, fetch the source with your distro tools (enable deb-src on Debian/Ubuntu first). Examples:

apt-get source <package-name>     # Debian/Ubuntu
dnf download --source <package>   # Fedora (install dnf-plugins-core)
yumdownloader --source <package>  # older CentOS/RHEL (install yum-utils)

If you just want readable reference code, a few canonical places to read implementations and the expected behavior are useful. The POSIX description of more documents the user-visible behavior and options (POSIX more spec). A compact, easy-to-read implementation is available in the FreeBSD source tree (), which is helpful for learning how pagers use terminal ioctls/terminfo, detect window size, buffer input, and handle files vs pipes.

Notes and cautions: implementations differ — some are simple forward-only pagers, others support back-scroll by buffering the whole file. Check the package license before reuse. For a more fully featured pager to study as an alternative, see less (more features, widely used).
