CentOS 8.x erlang man pages installation

There is no erlang-doc package to help with automatic installation of man pages along with erlang. Thus, we need to install man pages manually using:

1. Check version of erlang installed using:

   rpm -qa | grep erlang

2. Download erlang man pages tar gz of installed erlang version from https://www.erlang.org/downloads
3. tar xzf otp_doc_man*.tar.gz
4. mv man /usr/lib64/erlang
5. We should see man1, man3 etc. folders

   ls /usr/lib64/erlang/man

6. Try below command

   erl -man lists

7. If above does not works edit '/etc/man_db.conf' and insert following after other MANDATORY_MANPATH:

   MANDATORY_MANPATH                       /usr/lib64/erlang/man

8. After this we can open erlang man pages directly with man using:

   man lists
   man erlang

   Note that 'erl -man <module>' does not works. We can use either direct man command or man with directory name such as 'man -M /usr/lib64/erlang/man lists'.
