Estou em um sistema RHEL 8.3. Descobri que o built-in vime visão todos vim. Eles têm a mesma versão, mas compilados de forma diferente. Segue abaixo meu teste:
[root@192 ~]# which vim
/usr/bin/vim
[root@192 ~]# which vi
/usr/bin/vi
[root@192 ~]# ls -lah `which vim`
-rwxr-xr-x. 1 root root 3.0M Jun 3 2020 /usr/bin/vim
[root@192 ~]# ls -lah `which vi`
-rwxr-xr-x. 1 root root 1.2M Jun 3 2020 /usr/bin/vi
[root@192 ~]# vim --version

Por que eles mantêm duas versões diferentes? É um pouco estranho para mim. Se eles quiserem que vios usuários tenham um editor moderno, eles podem simplesmente fazer um link simbólico para vim. Por curiosidade, abaixo está o resultado em um sistema Ubuntu 20.04. Ambos vie vimapontam para nvim, o que é razoável.

/usr/bin/vi
root@u2004:~# which vim

viinicia (uma versão minimalista do) Vim em um modo que é compatível ao máximo com o clássicovi, empacotado comovim-minimal. Por outro lado,viminicia uma versão mais rica em recursos com configurações padrão mais modernas, empacotadas como arquivosvim-enhanced.Versões mais antigas do RHEL costumavam não ter o
/etc/alternativessistema, então é assim que eles costumavam fazer isso, e o RHEL ainda faz isso por causa da compatibilidade com versões anteriores.
