Load ~/.bashrc on SSH

On SSH login, ~/.bashrc was not load

Why?

A login shell first reads /etc/profile and then ~/.bash_profile.

A non-login shell reads from /etc/bash.bashrc and then ~/.bashrc.

An ssh command which does have a command, like ssh user@host, It will start a login shell, a login shell reads ~/.bash_profile.

An ssh command which does have a command, like ssh user@host :(: is command that does nothing), It will not start a login shell, therefore ~/.bashrc is what will be read.

Ref. Stackexchange - Why does remote Bash source .bash_profile instead of .bashrc

In my environment, there are no description in ~/.bash_profile to load ~/.bashrc.
